“…However, the presence of epichlorhydrin makes it toxic and limits its clinical application. 13,[31][32][33][34] Polyglycerol sebacic acid (PGS) is a biodegradable polymer, which is also widely used in tissue engineering and wound healing. This polymer is recommended for soft tissue engineering because it has elastomeric properties, biocompatibility, linear degradation rate, and nontoxic products.…”

Porous nanofibers were prepared from a combination of polyglycerol sebacate (PGS) and polyhydroxyethyl methacrylate (PHEMA) and loaded with tranexamic acid (TA) using the electrospinning method. The nanofibers were optimized for their morphology, diameter size, porosity, TA loading, release profile and mechanical behavior. Their cytotoxicity was studied based on 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyl tetrazolium bromide assay on L929 cells. The hemostasis control on a tail-cut model in rats was investigated. The best formulation contained 35% of the total polymers, 20% PGS and 10% TA in proportion to the total polymer quantity. These nanofibers had 64% porosity, 8.59% water sorption and 1.47% weight loss after 28 days with no cytotoxicity on the L929 cells. TA loaded nanofibers showed significantly less bleeding volume compared to the other groups, but no significant difference in bleeding time was seen with the blank nanofibers. In other words, the blank nanofibers alone had a hemostatic effect. TA loaded nanofibers were effective in bleeding control and hemorrhagic situations by reducing bleeding time and volume.

“…Recently, starch microspheres have attracted great interests as novel adsorption materials because of their suitable molecular rigidity, microporous structure 2 , high surface area 3 , and easy accessibility with the presence of active groups, such as hydroxyl and amino groups 4 . The preparation method of the specific crosslinked starch microspheres (CSMs) has been reported in our previous published works 5 , and then the adsorption properties of SCSM toward metal-ions, such as Cu 2+ , Co 2+ and Ni 2+ , have been reported too 6,7 . To date, however, there have been few publications reporting crosslinked starch microspheres as toxic organic compounds adsorbents.…”

The adsorption of pyridine onto crosslinked starch microspheres (CSMs) was investigated by experimental and theoretical methods. The adsorption capacity of CSMs towards pyridine increases with the increasing of pyridine concentration, and by lowering the temperature, adsorption would be accelerated. The adsorption behaviour of CSMs to pyridine is in agreement with the Langmuir isothermal equation. The research results show that the adsorption process is exothermic, and the adsorption force mainly derives from enthalpy changes. The thermodynamic parameters of adsorption process show that the adsorption behaviour of CSMs towards pyridine is of a physical type.
