Effective sensor communications

In sensor applications, greater care should be taken in the selection and application of polymer films to minimize modulus effects. The effect of elastic properties of the coating materials must be taken Into consideration in the interpretation of SAW sensor data. Alternatively, the sensor community ml t take advantage of the SAW sensitivity to elastic properties to devise more sensitive sensors, and to expand the applications of these sensors. 

All BFCs and biological sensors— no matter the type of device— have one important aspect in common the requirement for effective electronic communication between an electrode current collector and an enzyme. In the case of BFCs, it is obvious that efficient electron transfer must occur from enzyme to current collector (anode), and vice versa on the cathode, in order to ensure the highest possible ceU efficiency.

We have found that the communication between Ca2+ sparks and BK channels can be tuned by membrane potential (this study, Herrera et al 2001) and by the accessory / subunit (Brenner et al 2000, Petkov et al 2001). This effect can be accounted for based on the allosteric relationship between the BK channel voltage and Ca2+ sensors, whereby membrane potential depolarization favours a channel conformation that has a higher Ca2+ sensitivity. The /b subunit has a similar role to increase the apparent Ca2+ sensitivity of the a subunit.

Methods to electrically wire redox proteins with electrodes by the reconstitution of apo-proteins on relay-cofactor units were discussed. Similarly, the application of conductive nanoelements, such as metallic nanoparticles or carbon nanotubes, provided an effective means to communicate the redox centers of proteins with electrodes, and to electrically activate their biocatalytic functions. These fundamental paradigms for the electrical contact of redox enzymes with electrodes were used to develop amperometric sensors and biofuel cells as bioelectronic devices. 

While this longitudinal loss is detrimental for communications or applications involving transport of energy over long distances, this property is potentially very beneficial for sensors utilizing capillaries. Most of the leaky modes will directly excite molecules immobilized on the inner surface of the capillary. The effective attenuation for each of the leaky modes is found to be inversely proportional to the diameter of the capillary and exhibits unacceptable values for all modes with the exception of a few lower order modes, corresponding to almost normal incidence at the proximal end of the capillary, i.e., Oq < 5", ...
