Heparinization of gas plasma-modified polystyrene surfaces and the interactions of these surfaces with proteins studied with surface plasmon resonance.
Polystyrene surfaces obtained by spin-coating a solution of polystyrene in toluene on a gold layer were functionalized with carboxylic acid groups by preadsorption of the sodium salt of undecylenic acid, followed by an argon plasma treatment. A conjugate of albumin and heparin (alb-hep) was covalently immobilized onto the functionalized surface via preactivation of carboxylic acid groups with a...
متن کاملDirect DNA Immobilization onto a Carbon Nanotube Modified Electrode: Study on the Influence of pH and Ionic Strength
Over the past years, DNA biosensors have been developed to analyze DNA interaction and damage that have important applications in biotechnological researches. The immobilization of DNA onto a substrate is one key step for construction of DNA electrochemical biosensors. In this report, a direct approach has been described for immobilization of single strand DNA onto carboxylic acid-functionalize...
متن کاملNew Hybrid Nanomaterial Derived from Immobilization of 4-Formyl Benzo-9-Crown-3 Ether onto the Mesopores of MCM-41
In this work, we report a new hybrid nanomaterial based on the immobilization of 4-formyl benzo-9-crown-3 ether (FB9C3) onto the mesopores of MCM-41. First, the mesoporous molecular sieve MCM-41 was covalently grafted with 3-aminopropyl triethoxysilane to give aminopropyl modified MCM-41 (AmpMCM-41). Reaction of this material with FB9C3 afforded the B9C3-AmpMCM-41 hybrid nanomaterial. The prepa...
متن کاملNanometric grafting of poly (N-isopropylacrylamide) onto polystyrene film by different doses of gamma radiation
Poly N-isopropylacrylamide was successfully grafted onto a polystyrene cell culture dish by gamma ray. In this study, the effect of a radiation dose (radiation absorbed dosages of 10, 20, 30, 40 KGy) under appropriate temperature and grafting conditions was investigated. The FTIR analysis showed the existence of the graft PNIPAAm on the substrate. The optimal value of the dose for grafting was ...
متن کاملImmobilization of Cobaloxime on MCM- 41
This work reports, immobilization the Cobaloxime [Co (DH) Cl;DH,dimethylglyoximato)] onto the MCM- .The surface of MCM- was initially functionalized with -aminopropyltrimethoxysilane and -pyridine. For the electrostatic immobilization this was reacted with Cobaloxime and immobilization was achieved by an electrostatic interaction between the Co Cobaloxime and the N of the pyridine and NH amine....
