Polyurethane surfaces were modified by covalent immobilization of different molecular weight heparins (fractionated Mw ~3000 Da, and unfractionated Mw ~17,000—19,000 Da) and examined by ESCA, AFM, and contact angle goniometer. The effect of these different surface-immobilized heparins on blood...
The bioactivity of a novel composite of carbonate-containing low-crystallinity nanoparticle hydroxyapatite (HA) and a chitosan—phosphorylated chitosan polyelectrolyte complex (PEC) was evaluated in vitro and in vivo. The HA—PEC nanocomposite with complicated porous structure was prepared by a...
Amphiphilic scorpion-like macromolecules (AScMs), that self-assemble as nanocarriers, were evaluated for intracellular delivery. To qualitatively examine the intracellular fate of AScMs in human umbilical vein endothelial cells (HUVECs), representative polymers (M12P5) were labeled with a...
The lipase-producing strain, Arthrobacter sp. (ABL), isolated was immobilized in Ca-alginate beads by entrapment. The alginate beads were prepared as an aqueous mixture of sodium alginate, the cells and CaCl2 to increase its reusability, and overall enzyme stability. Various parameters like...
In this study, the solubilization of poor water-soluble drugs using N-acyl, O-acyl-N-trimethyl chitosan chloride (ATMC) micelles as a carrier system was investigated. Three series ofATMCs were synthesized by N-trimethyl chitosan chloride (TMC) with substitutions of 21.3, 44.8, and 45.2% as start...
A simple, fast, inexpensive sensitive/selective nucleic acid sensor based on the quartz crystal microbalance system (QCM) was developed for the detection of telomerase. A specially designed oligonucleotide probe, that is complementary to the...
