Diagnostic chip

The demand for mass-producible, low-cost diagnostic chips has had a significant impact on the development trends for optical sensor platforms. Arguably the most important characteristics of recent systems are the integration of multiple functionalities onto a single platform, the ability to perform multianalyte detection and the production of low-cost sensor platforms. These strategies are intended to maximise the viability of a device for development as a commercial product. 

Meisler I share your view that the interaction of polymorphic variants in these Na channels could have profound effects on what we consider as psychiatric function. It is going to be very interesting one can imagine in the future that neurological exams will include diagnostic chips for scanning mutations in aU the channels simultaneously. We have defined two common haplotypes in the human SCNIA channel. These common variants could be analysed in your population. I wanted to ask particularly about the Roman family. It looked like you had linkage.

The previously mentioned developments were all carried out on serum samples, and in an effort to develop a diagnostic system with an outlook toward a point-of-care application, it would be favorable to offer a diagnostic chip that operates with whole blood as the input sample. In view of this Lenshof et al. (2009) and Tajudin et al. (2013) coupled an acoustically driven plasmapheresis chip to the porous silicon PSA sandwich microarray assay. The plasmapheresis chip eliminated...

The development of protein chip assays to determine protein function using purified components is a rapidly advancing area. Automated systems for the assay of protein function on chips in parallel for thousands of proteins simultaneously will likely be available in the next few years. These miniaturized arrays will be useful for basic research as well as for diagnostics and drug development. For instance, the combination of protein chips with combinatorial chemistry will allow the simultaneous screening of vast collections of small molecules against vast collections of potential target proteins. 

Recent developments in microsystems technology have led to the widespread application of microfabrication techniques for the production of sensor platforms. These techniques have had a major impact on the development of so-called Lab-on-a-Chip devices. The major application areas for theses devices are biomedical diagnostics, industrial process monitoring, environmental monitoring, drug discovery, and defence. In the context of biomedical diagnostic applications, for example, such devices are intended to provide quantitative chemical or biochemical information on samples such as blood, sweat and saliva while using minimal sample volume. 

It is important to note that the enhancements mentioned above are achievable using current planar microfabrication techniques and the resultant sensor chips are mass-producible, low-cost and disposable and also have the potential to be integrated into a variety of diagnostic microsystems. This work has significant implications for the production of low-cost, yet efficient measurement platforms for applications in modem society.

In this chapter we first discuss the fundamentals and the design aspects of an integrated optical YI sensor (Sect. 10.2), followed by a description of the experimental setup (Sect. 10.3). In the result section (Sect. 10.4) both protein and vims detection experiments are discussed. Section 10.5 demonstrates the use of microfluidic chips for efficient sample handling in combination with the YI sensor. This chapter concludes with a discussion on the prospects of the sensor for point-of-care diagnostics.
