Just a drop of blood the new sensor can measure cancer and cholera

According to the latest issue of "Journal of the American Chemical Society," it reported that the International team includes Canadian researchers have developed a new, including graphene sensors. The biosensor to detect cholera toxin not only has a very high sensitivity, but also provide early diagnosis for cancer and other diseases. Surface plasmon resonance (SPR) sensor is a medical diagnosis of optical technology for high sensitivity and specificity. The researchers found that adding graphene may cause SPR sensor signal multiplied, so that a single molecule can anchor an ultrathin layer of a particular disease signal.

The sensor can detect within minutes of the cholera toxin, by contrast, the current detection techniques require hours or even days. The technology can also be extended to detect almost any including cancer disease markers.


The researchers said that in addition to faster and greatly improved due to the sensitivity of the sensor can be more easily detected small amounts of biological markers, in order to create conditions for the early diagnosis and prognosis of cancer and other diseases. This means that, just use a drop of blood sample from a patient acupuncture, can detect the biomarkers of disease.

SPR biosensor is significantly larger than the standard enzyme-linked immunosorbent assay (ELISA) has a higher sensitivity, laboratory-grown graphene proof than before the use of other forms of graphene is more suitable for the development of new sensors. Graphene is called chemical vapor deposition growth technique to create a large-area graphene nearly defect-free, uniform surface of the graphene helps amplifying the sensor signal.

Electromagnetic interference shielding data center cabling system

1, interfering with the data center cabling system

Cabling system consists of several subsystems, signal size of each subsystem used, frequency, etc. are not the same height, so there is interference, as well as the mutual interference between the various loads. To sum up, the integrated wiring system has the following sources of interference.

1.1 sources of interference from the data center within the building

(1) distribution network and the distribution box to generate high-frequency interference.

(2) high-power electric motor electric spark generated by harmonic interference.

(3) fluorescent lamps, electronic ballasts produce interference.

(4) High-frequency switching power supply interference.

(5) generated by the telephone ringing current interference.

(6) Information processing device generates periodic pulse interference.

If the cabling system can not keep a safe distance from these sources may be used to reduce or eliminate shielding system interference sources above the interference of cabling system.

1.2 the source of interference from outside the data center building

Sources of interference from outside the data center architecture are:

Radar, radio transmission equipment, mobile phone base stations, high-voltage wire, electrified railways, lightning strike zones in the interference signal environment and so on.

Obviously intelligent building external interference sources have a high electric field strength, when external cabling systems exist one or more sources of interference should be shielded system.

1.3 sources of interference from the surrounding environment cabling system

Cabling system noise level ambient interference signal field strength or integrated wiring system also should be shielded to protect the system exceeds the following requirements.

(1) computer local area network, if the frequency of the interference signal is introduced l0kHz ~ 600MHz, its field strength of 1V / m; frequency of 600MHz ~ 2.8GHz interference signal field strength of 5V / m.

(2) telecommunications terminal equipment, is introduced through the signal line and other DC or AC frequency of the interfering signal introduced into 15 ~ 80MHz, the field strength of 3V / m (amplitude modulation 80%, 1kHz).

Terminal Equipment (3) with analog / digital terminal interface to provide telephone service, the noise level exceeds 40dB total bandwidth should be less than 200MHz.

(4) The background noise level should be at least 12dB smaller than the reference.

2, comprehensive sets of wiring system anti-jamming measures

Electric field strength interference waves emitted cabling system exceeds a predetermined value, whether factors that need protective measures is more complex, which is the most harmful anti-electromagnetic interference and electromagnetic radiation. EMI issues related to the cabling system can work properly; electromagnetic radiation is related to the safety of cabling system under normal operating conditions information from being stolen by other persons, or causing electromagnetic pollution.

Conducting integrated wiring systems engineering design must be in accordance with the requirements of the construction unit, carry out a detailed arrangement and design, selecting appropriate protective measures.

2.1 shielding measures to reduce electromagnetic interference

Metal casing (1) Information systems, cable shield and metal trunking and other buildings in the introduction frame or equipotential bonding. Information system lightning protection zone in which the magnetic field strength attenuation should be calculated, to take appropriate measures to shield according to the results.

(2) The data center should not be located in high-rise buildings, should lower center of the building. Related equipment to try to stay away from the building facade. Take appropriate measures in accordance with the requirements of lightning protection zones shield and information equipment, electromagnetic field generated when the lightning to the inner decay.

(3) The information device is a non-metallic housing and the shield of the building did not meet the requirements, the importance of information equipment room or equipment based on the direct installation of metal screen or shielded room, shielded metal shielded rooms and other potential connection with phase.

Outdoor line of shielding measures 2.2

Outdoor wiring shield to note the following.

(1) the need to protect the local potential should use shielded cables and both ends of the shielding layer is peer connections, the shield after the junction of the lightning protection zones should also be equipotential connection.

(2) the use of the cable metal-containing components, shall at all into the household of the metal plugs, metal tidal layer and the metal strengthening the core metal member equipotential connection.

Room (3) Building interconnecting cables should be laid in a metal pipe, metal pipe ends to be connected to other potential electrical connections and connections to bring each building. Cable conduits must be equipotential connection. If between adjacent buildings have power and communication cables, the grounding device should be connected to each other.

2.3 Strengthening internal cabling system structure and materials of immunity

This is mainly possible electromagnetic interference requirements for products and equipment may be affected by electromagnetic interference raised. Specific requirements in the manufacturing process is tested to the appropriate standard.

Overall, computer equipment, communications equipment and electronic equipment and other products shape the structure should be made of a metal material box, box, cabinet or shelf, making it in the form of a Faraday cage, a ground terminal, and well grounded. This ability to somehow enhance immunity and radiation protection equipment.

For cable selection Cabling system must meet the system requirements, combined with the buildings surrounding electromagnetic environment into account, usually anti-jamming capability and transmission capacity is the major consideration, but also to consider the economic cost.

Select cables and cabling system connecting hardware, when determining whether a category that you want to ensure consistency. If you choose to shield the cables and connecting hardware must be shielded, and have a good grounding system. Link cabling system commonly used twisted pair, UTP has the ability to absorb and emit electromagnetic waves.

2.4 Note from the equipment and transmission lines between the different sources of interference

In addition to the use of shielded cabling system, well grounded in order to improve their own immunity, radiation protection, but also as far away from interference sources, in order to reduce its impact on the normal operation of the system, improve the reliability of systems and equipment to make Data center cabling system truly become a standard, standard cabling system.

Through a number of experiments shows that when the interference source distance transmission line at different distances, the distortion degree of the transmission signal is different. Therefore, in the construction and installation process should pay attention to the relationship between the wiring system and the distance from the source of disturbance, in strict accordance with standard design, construction, and make the appropriate testing to ensure normal and reliable cabling system.

Why periphery and core are to be considered when selecting a CPU

New products bring to market quickly - with increasing design complexity. To help customers succeed, has been certified for ARM Accredited Engineer Future Electronics' MCU 300 engineers.

The time factor more than ever now plays a crucial role in product development and in meeting the timeframe for the launch. Choosing a core that does not exactly meet the requirements can jeopardize the entire schedule. The technical distributor Future Electronics is therefore on the intensive training of its field application.

300 engineers have been in the last year certified for ARM Accredited Engineer MCU and can now offer extensive assistance in the core selection. Uwe Knipping, technical solutions manager at Future Electronics, explains in an interview with the ELEKTRONIKPRAXIS which criteria are of particular importance.

ELEKTRONIKPRAXIS: What were the reasons for the ARM certification of engineers at Future Electronics?

Uwe Knipping: Through our work with customers, we found that great need for education is around choosing a suitable cores. As a technical distributor we set at the beginning of the development work on with our assistance around the choice of a core and place here the course for the project's success.

Participation in the ARM AAME program and the associated certification of Future Field Application Engineers will create the necessary basis of trust with our customers and at the same time laid the foundation to meet the different advisory requirements. By profound knowledge about ARM cores, we are even better able to design teams the customer from the start of a new project at the right decision to accompany architecture.

Why is this help today in the project so important?

Through ARM-based cores a vast variety of CPU choices has emerged in the last five years. Many manufacturers use the same core for its microcontroller, so that differentiation at first glance is not easy. Our experiences have shown that when choosing a microcontroller knowledge is tacitly over the core.

The manufacturer informed about what they have implemented around the core to the periphery. They provide customers with a wealth of material on data sheets and examples. Often but not find the time for individual advice on specific project. Here we jump and connect our core specific knowledge with the peripheral requirements.

Important is the vendor-neutral advice that we can with our overview of various ARM-based products and proprietary cores, such as the MIPS or AVR platforms, offer through our broad-based linecard in order to arrive at an optimal solution for specific customer needs.
