Biological and Chemical Sensors Made from Microporous and Nanofibrous Membranes

A presentation by Gang Sun, Ph.D.

ABSTRACT:

 

Microporous and nanofibrous membranes possess ultrahigh specific surface areas which can serve as solid supports for highly interactive media with chemicals and locally concentrate and enhance chemical reactions on the surfaces.  Surface interactive nanofibers in the membranes could bring inbiological agents such as antibodies. With a combination of the above mentioned features of nanofibers and biologically specific Enzyme-linked immunosorbent assay (ELISA), highly sensitive and selective colorimetric sensors for fumigants and antibiotics were developed based on use of the microporous and nanofibrous membrane materials.
