Intelligent biomembrane obtained by irradiation techniques

Stimuli‐Responsive Chitosan‐graft‐Poly(N‐vinylcaprolactam) as a Promising Material for Controlled Hydrophobic Drug Delivery

“…In recent years, much interest has been focused on water‐soluble stimuli‐responsive polymeric systems that show a phase transition in response to external stimuli such as temperature, pH, specific ions, and electric field 7–9. Among all intelligent polymers studied, temperature and pH‐responsive polymeric systems have drawn much attention, because temperature and pH are important environmental factors in the body, and some disease states manifest themselves by a change in temperature and/or pH 10–12.…”

IPN’s of acrylic acid and N-isopropylacrylamide by gamma and electron beam irradiation

“…In recent years, temperature and pH sensitive hydrogels have been investigated widely because of their unique properties and versatile applications in medicine and biotechnology, as well as in drug delivery [1][2][3][4]. However a serious limitation of hydrogels in many applications is the low mechanical strength of such gels when highly swollen.…”

Nanoporous Membranes of Hydrogen‐bridged Smectic Networks with Nanometer Transverse Pore Dimensions

“…Nanopores are created in lithographic materials using high-resolution lithographic techniques, such as electron beam or ion beam lithography. [21,22] A bottom-up approach, using self-organization by the controlled microphase separation of block copolymers and the subsequent removal of one of the blocks, provides a variety of pore shapes and sizes depending on the molecular weight and types of micellar phases. [23][24][25] For smaller dimensions supramolecular dendritic structures can self-assemble into pores with a well-controlled inner chemical nature.…”
