Development of poly(l-lactic acid) hollow fiber membranes for artificial vasculature in tissue engineering scaffolds

Supercritical processing of CO 2 -philic polyhedral oligomeric silsesquioxane (POSS)-poly( l -lactic acid) composites

“…Additionally, PLA is widely used in biomedical applications, such as matrix for controlled release drug delivery systems, scaffolds for bone tissue engineering, and artificial vasculature due to its biocompatible and biodegradable nature [8][9][10][11][12][13]. PLA is a racemic mixture of L-and D-isomers and the final properties depend on the ratio of these isomers present in the structure.…”

Surface zwitterionization of hemocompatible poly(lactic acid) membranes for hemodiafiltration

“…Therefore, the key to preparing hemocompatible PLA membranes is to design and construct compatible and anti-fouling surfaces [20,21]. Besides, some hydrophilic polymers have been directly or indirectly introduced to the PLA matrix or surface via blending [22][23][24], self-assembly [25,26], surface grafting [27] and so on. Among them, polyethylene glycol (PEG) and polyethylene oxide (PEO) are the most extensively studied and applied [28].…”

Development and evaluation of elastomeric hollow fiber membranes as small diameter vascular graft substitutes

“…Several techniques have been applied in efforts to fabricate biocompatible SDVGs, such as electrospinning [10–12], phase inversion [13–22], molding [23–25], and combinations of methods [26–29], but no ideal technique exists to date. Polymers as a group offer significant versatility in vascular graft design due to their ease of customization and flexibility.…”

“…Polymers as a group offer significant versatility in vascular graft design due to their ease of customization and flexibility. Polylactic acid (PLA) [13], polycaprolactone (PCL) [14, 15], poly(D,L-lactide- co -glycolide) (PLGA) [24], poly(glycerol sebacate) (PGS) [23, 30], polyimides [17, 18, 20], polyurethanes [10, 26, 29], and other polymers [19, 21] have been used successfully for the fabrication of candidate SDVGs. These SDVGs have also shown encouraging results.…”
