2004 SEP 14 - (NewsRx.com & NewsRx.net) -- Temperature and pH responsive polymers react to environmental changes.
According to recent research published in the Journal of Controlled Release, "poly(N-isopropylacrylamide) (PNIPAm) co-polymers responsive to temperature and pH were prepared with side chain chemistries in order to exhibit phase transitions under physiologically relevant conditions."
"Fluorescence spectroscopy, gel retardation assays, dynamic light scattering and atomic force microscopy were used to characterize the binding of plasmid DNA to these materials and to control polymers poly(ethyleneimine) (PEI) and poly(ethyleneimine)-octanamide," ...
