Synthesis of electroactive tetraaniline grafted polyethylenimine for tissue engineering

Synthesis of biodegradable and electroactive multiblock polylactide and aniline pentamer copolymer for tissue engineering applications.

To obtain one biodegradable and electroactive polymer as the scaffold for tissue engineering, the multiblock copolymer PLAAP was designed and synthesized with the condensation polymerization of hydroxyl-capped poly( l-lactide) (PLA) and carboxyl-capped aniline pentamer (AP). The PLAAP copolymer exhibited excellent electroactivity, solubility, and biodegradability. At the same time, as one scaff...

Electroactive oligoaniline-containing self-assembled monolayers for tissue engineering applications.

A novel electroactive silsesquioxane precursor, N-(4-aminophenyl)-N'-(4'-(3-triethoxysilyl-propyl-ureido) phenyl-1,4-quinonenediimine) (ATQD), was successfully synthesized from the emeraldine form of amino-capped aniline trimers via a one-step coupling reaction and subsequent purification by column chromatography. The physicochemical properties of ATQD were characterized using mass spectrometry...

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...

Study of Fibroblast Cells Behavior on the Acrylic Acid Co2 Pulsed Laser Grafted Silicone Elastomer for Tissue Engineering Application

Polyethylenimine-grafted polycarbonates as biodegradable polycations for gene delivery.

Polycations as one of non-viral vectors have gained increasing attentions. In this paper, polyethylenimine(PEI)-grafted polycarbonates (PMAC-g-PEIx) were synthesized as a kind of biodegradable polycations for gene delivery. Backbone polymer, poly(5-methyl-5-allyloxycarbonyl-trimethylene carbonate) (PMAC), was synthesized in bulk catalyzed by immobilized porcine pancreas lipase (IPPL). Then, PMA...
