摘要:
The present invention involves the isolation of plant based CNCs from the leaves of S. cumini. For the formation of NCs, a novel greener approach using S. cumini LE as reducing agent for in situ impregnation of AgNPs as fillers into CNCs as matrix is reported. The silver nitrate solution in three different concentrations of 1 mM, 5 mM and 10 mM was used to form NCs where AgNPs have been incorporated into CNCs matrix. The CNCs and NCs were characterized using SEM, TEM, XRD, Zeta potential, FT-IR, and UV-Vis spectroscopy. NCs developed in the form of film and ointment showed strong antimicrobial activity against both gram negative and gram positive bacteria. NCs wound dressing is capable of regulating wound exudates and providing moisture to wound responsible for faster healing of acute wounds. The observations from histopathological and biochemical assays confirmed that NCs enhance healing because of lesser inflammation, rapid angiogenesis, early collagen formation and enhanced rate of reepithelization.

摘要:
An embodiment includes a wound dressing comprising: a shape memory polymer (SMP) foam, including open cells, having first and second states; and a hydrogel (HG) included within the cells; wherein (a) in a first position a composite, including the SMP foam and the HG, is configured to be located proximate a hemorrhagic tissue with the SMP foam in the first state; (b) in a second position the composite is configured to be expanded to the second state against the hemorrhagic tissue when the SMP foam is plasticized at 37° C depressing a glass transition temperature (T g ) of the SMP foam to below 25° C. Other embodiments are described herein.
