Researches at the University of California at San Diego
have invented an optical encoding method for encoding
micron-sized nanoporous semiconductor, conductor, or
dielectric particles to be used in biological and /
or chemical screening, sensing,or identification application.
Particles are optically encoded by changing process
conditions during porosification. The particles can
thereby be chemically modified for specific biological,
biomedical, electronic, or environmental applications.
The method, employing reflection spectroscopy, does
not have the disadvantage of photobleaching inherent
with fluorophores. Additionally, fluorescent analytes
do not interfere with the particle signal. Moreover,
the method is biocompatable, and can be applied to the
screening of large numbers of analytes in vivo.
