Abstract

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. We have developed a range of glucose nanosensors based on the disassociation of Con A aggregated, dextran coated 20 nm gold colloids. By modifying the nanosensor fabrication in terms of dextran molecular weight, size of gold colloid and the amount of Con A used, we are able to tune the dynamic glucose sensing range. Our sensors can readily report glucose concentrations up too 40 mM using simple absorption measurements, monitored at a near-red arbitrary wavelength.
