The formation of small-pore gels by an electrically charged agarose derivative.


Previous studies have shown that, during the formation of an underivatized agarose gel, agarose molecules laterally aggregate to form thicker fibers called suprafibers; the suprafibers branch to form a gelled network. In the present study, electron microscopy of thin sections is used to investigate both the thickness and the spacing of the fibers of gels… (More)
