Electrospun polylactic acid nanofiber membranes as substrates for biosensor assemblies
نویسندگان
چکیده
Biotin has been successfully incorporated into polylactic acid (PLA) nanofibers through electrospinning to prepare membrane substrates for biosensors based on biotin–streptavidin specific binding. Biotin incorporated PLA nanofiber membranes were characterized with scanning electron microscopy (SEM), electron probe microanalysis (EPMA), and confocal microscopy. Under optimized conditions, small fiber size and uniform morphology were achieved for PLA nanofibers with and without biotin incorporation. Sulfur mapping indicated a non-uniform distribution of b e m ©

متن کاملIn vitro and in vivo evaluations of a novel post-electrospinning treatment to improve the fibrous structure of chitosan membranes for guided bone regeneration.
Electrospun chitosan membranes have been investigated for guided bone regeneration but are susceptible to swelling, dissolution, and loss of biomimetic nanofiber structure due to residual acid salts. A novel process was investigated for acidic salt removal from chitosan electrospun in 70% trifluoroacetic acid (TFA) by treating with triethylamine (TEA)/acetone and di-tert-butyl dicarbonate (tBOC...
