Electrospun fibrinogen-PLA nanofibres for vascular tissue engineering

Characterization of a co-electrospun scaffold of HLC/CS/PLA for vascular tissue engineering.

Novel scaffolds for vascular tissue engineering were fabricated by co-electrospinning human-like collagen/chitosan and polylactic acid at room temperature and normal pressure. By studying the effects of composition and collecting distance on the morphology of electrospun meshes, we determined that the proper collecting distance and the concentration of the solution are the keys to the success o...

fabricating electrospun poly(3-hydroxybutyrate)/hydroxyapatite nanocomposite scaffold for tissue engineering application

. در رســاله ی حاضر، ابتدا داربست نانوالیاف سه بعدی متخلخل به روش الگوبرداری تصویری شبیه سازی شد. با استفاده از طراحی آزمایش به روش تاگوچی پس از ساخت داربست های پلی (3- هیدروکسی بوتیرات) (p3hb) شناسایی رفتار پارامترهای موادی مثل لزجت سیال پلیمر، فراریت و رسانایی الکتریکی محلول پلیمری و پارامترهای دستگاهی مثل دبی حجمی سیال، ولتاژ الکتریکی و فاصله نازل تا جمع کننده صورت گرفت. بعد از محاسبه ی خصوص...

Poly(lactic acid) (PLA) Nanofibers for Bone Tissue Engineering

Electrospun scaffolds for tissue engineering of vascular grafts.

There is a growing demand for off-the-shelf tissue engineered vascular grafts (TEVGs) for the replacement or bypass of damaged arteries in various cardiovascular diseases. Scaffolds from the decellularized tissue skeletons to biopolymers and biodegradable synthetic polymers have been used for fabricating TEVGs. However, several issues have not yet been resolved, which include the inability to m...

Actuating individual electrospun hydrogel nanofibres

The actuation of a single hydrogel nanofibre is measured for the first time by AFM. The actuation stress generated was comparable to that produced by skeletal muscle and the actuation rate was significantly increased by the nanoscale dimensions of the fibre.
