Hemocompatibility assays of poly (lactic acid) nanostructures: A bird’s eye view

Abstract

The usage of clinical devices in the cardiovascular treatment, hemodialyze system and other biomedical applications has improved recently. Direct contacts of biomaterials like poly(lactic acid) biopolymer with blood result in the activating of platelets, white blood cells , coagulation structure and complement cascades. Poly(lactic acid) is a sustainable, renewable, compostable, biobased, biodegradable, bioabsorbable , biocompatible polymer. This polymer has many applications in the synthesis of blood contacting mats like nanofibrous vascular scaffolds and hemodialyze nanosheets.Mechanical interruption of the blood vessel wall throughout grafting of cardiovascular devices starts local hemostatic replies. Improving the safety of the blood contacting nanostructure grafts is a main necessity. The controlling of the interactions of proteins and platelets to the surface of a blood contacting biomaterial is a significant factor. So, the assessments of these material’s influences on blood are necessary.This article references more than 80 articles published in the last decade and reviews the latest hemocompatibility assays of poly(lactic acid) nanostructures used in the blood contacting field.
