New tubular conduits have been developed for the regeneration of peripheral nerves and the repair of defects that are larger than 3 cm. The conduits consist of a combination of poly(L-lactide) nanofibers and chitosan composite fibers with chitin nanofibrils. In vitro studies were conducted to assess the biocompatibility of the conduits using human embryonic bone marrow stromal cells (FetMSCs).

Article Synopsis
- The amphiphilic block copolymer was created by reacting chain transfer agents during the polymerization process of specific acrylamides, resulting in a copolymer with a conversion rate of 68% and a high molecular weight of 490,000 g/mol.
- The study focused on the colloidal chemical properties of Langmuir monolayers and Langmuir-Blodgett films formed from the synthesized block copolymer, comparing it with a functional polymer made of poly(-isopropylacrylamide).
- Results indicated that the monolayers of the block copolymer exhibited high collapse pressures regardless of subphase acidity, and their Langmuir-Blodgett films displayed a unique comb-like structure
Conducting Composite Material Based on Chitosan and Single-Wall Carbon Nanotubes for Cellular Technologies.
