Cell adhesion and growth enabled by biomimetic oligopeptide modification of a polydopamine-poly(ethylene oxide) protein repulsive surface
Protein-repulsive surfaces modified with ligands for cell adhesion receptors have been widely developed for controlling the cell adhesion and growth in tissue engineering. However, the question of matrix production and deposition by cells on these surfaces has rarely been addressed. In this study, protein-repulsive polydopamine-poly(ethylene oxide) (PDA-PEO) surfaces were functionalized with an...

بررسی نقش گفتمان در شکل گیری یا کاهش انگیزش فراگیران زبان خارجی موضوع تحقیق نسبتاً جدیدی است. از این رو، تحقیقات کمی در این زمینه وجود دارد. به منظور پر کردن این خلاء ، مطالعه کنونی به بررسی فرآیند گفتمان مدار شکل گیری یا کاهش انگیزش دانشجویان ایرانی زبان انگلیسی پرداخت. نخست، این مطالعه به صورت آزمایشی با 7 نفر (? دانشجوی پسر و 5 دختر) از دانشجویان سال دوم دوره ی کارشناسی زبان و ادبیات انگلیسی ...
Colorimetric enantiorecognition of oligopeptide and logic gate construction based on DNA aptamer-ligand-gold nanoparticle interactions.
Enantiomers of chiral biomolecules and drugs have distinct pharmacological and toxicological activities. . Consequently, separation and determination of enantiomers are vital in pharmaceutical and chemical industries. It is wellknown that the l-enantiomer of oligopeptides naturally exists in the organism; however, d-oligopeptides are regarded as potential therapeutic agents because of their res...
متن کاملPolydopamine-Supported Lipid Bilayers
We report the formation of lipid membranes supported by a soft polymeric cushion of polydopamine. First, 20 nm thick polydopamine films were formed on mica substrates. Atomic force microscopy imaging indicated that these films were also soft with a surface roughness of 2 nm under hydrated conditions. A zwitterionic phospholipid bilayer was then deposited on the polydopamine cushion by fusion of...
متن کاملFormation of fluorescent polydopamine dots from hydroxyl radical-induced degradation of polydopamine nanoparticles.
This study describes the synthesis of fluorescent polydopamine dots (PDs) through hydroxyl radical-induced degradation of polydopamine nanoparticles. The decomposition of polydopamine nanoparticles to fluorescent PDs was confirmed using transmission electron microscopy and dark-field microscopy. The analysis of PDs by using laser desorption/ionization time-of-flight mass spectrometry revealed t...
