Immobilization of gelatin onto poly(glycidyl methacrylate)-grafted polycaprolactone substrates for improved cell-material interactions.
To enhance the cytocompatibility of polycaprolactone (PCL), cell-adhesive gelatin is covalently immobilized onto the PCL film surface via two surface-modified approaches: a conventional chemical immobilization process and a surface-initiated atom transfer radical polymerization (ATRP) process. Kinetics studies reveal that the polymer chain growth from the PCL film using the ATRP process is form...

آنزیم تریپسین در شرایط قلیایی ناپایدار می باشد .و فعالیت پروتئولیتیکی تریپسین منجربه خود هضمی آن در جایگاههای خاصی می گردد. بنابر این آنزیمی با ناپایداری بالا محسوب میگردد. در سالهای اخیر موفق شدند که با ایجاد تغیرات شیمیایی با اضافه کردن فلزات خاص ، کلسیم و یا عمل استیلاسیون منجر به افزایش پایداری آنزیم تریپسین گردند. مطالعات در حال حاضر نشان می دهد که تریپسین استیله شده فعالیت آنزیمی خود را ...
15 صفحه اولImmobilization of hexa-arginine tagged esterase onto carboxylated gold nanoparticles.
Hexa-arginine tagged esterase was efficiently immobilized onto carboxylated gold nanoparticles (AuNP-COOH) and its enzyme activity was investigated by monitoring the absorption spectrum of an enzyme substrate, p-nitrophenol butyrate.
متن کاملControlled Release Ammonio Methacrylate Copolymer-Based Microspheres of Oxypentifylline
The objective of this work was to formulate and evaluate a controlled-release Oxypentifylline microspheres that fulfill the requirements for extended release medications using Ammonio Methacrylate Copolymer RS100 as polymeric material. The microsphere were prepared by quasiemulsion solvent diffusion technique. The effect of process variables such as drug to polymer ratio, stirring rate, and con...
متن کاملInvestigation of microstructure of glycidyl methacrylate/a-methyl styrene copolymers by 1D- and 2D-NMR spectroscopy
The copolymers of glycidyl methacrylate/a-methyl styrene were synthesized. The quantitative C{H}-NMR spectroscopy was used to determine the copolymer compositions. The distortionless enhancement by polarization transfer, C-H heteronuclear single quantum coherence and total correlation spectroscopy were used for the complete spectral assignment of C{H}and H-NMR spectra.
