Portable FRET Sensing of Proteins, Hormones, and Toxins Using DNA Aptamers and Quantum Dots

Jackson G.W., Strych U., Frank E., Willson R.C., Ballerstadt R., McNichols R.J., BioTex, Inc., US

There is an urgent need to develop methods and devices that make the monitoring of any compound of interest in the public water system more reliable, more sensitive and more economical. We are developing a [...]

Force Discrimination for Enhanced Biosensor Specificity of Micro-Retroreflector Assays

Knoop J.D., Kemper S.M., Sherlock T., Cacao E., Ruchhoeft P., Willson R.C., University of Houston, US

In nearly all diagnostic/bioanalytical methods other than mass spectrometry, what is actually detected is a label of some sort, and the sensitivity and simplicity of detection of this label limits assay performance. Non-specific interactions between [...]

Micro-Retroreflectors in Immunoassays and Biosensors

Kemper S.M., Sherlock T., Knoop J.D., Cacao E., Ruchhoeft P., Atmar R.L., Willson R.C., University of Houston, US

Many current bioanalytical and diagnostic methods rely on labeling the species of interest and specialized detection equipment to monitor the label. Common techniques suffer from signal loss or degradation and require the use of equipment [...]
