Biodegradable Polylactic Acid (PLA) Microstructures for Scaffold Applications

Study of PLA Printability with Flexography Ink: Comparison with Common Packaging Polymer

Today, the economic consumption of biodegradable polymers is of capital importance in many applications. One of the most commonly used biopolymers is polylactic acid (PLA). The printability of the biodegradable film has not been fully investigated. This work tested the printability of polylactic acid (PLA) films and compared the print qualities to common packaging films like low density pol...

The Application of the Bio-material Pla in Biodegradable Coronary Stents

Heart disease is a common medical condition that affects hundreds of thousands of people each year in the United States alone. In response, scientists have spent decades researching technologies to treat this disease. Coronary stents are a technology developed to keep collapsing heart vessels open to promote proper blood flow and prevent further cardiovascular complications. Since the 1970s, th...

Melt blown Polymeric Nanofibers for Medical Applications- An Overview

Nanofibers or microfibers produced by either of the techniques are used in tissue restoration, compact organs, construction of biocompatible prostheses, cosmetics, face masks, bone substitutes, artificial blood vessels, and valves; and drug delivery applications [3]. Scaffold materials produced from nanofibers offer a very large surface area that supports cell growth [2]. Polymers such as Polyg...

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

Preparation and investigation of polylactic acid, calcium carbonate and polyvinylalcohol nanofibrous scaffolds for osteogenic differentiation of mesenchymal stem cells

Objective(s): In this study, the effect of electrospun fiber orientation on proliferation and differentiation of mesenchymal stem cells (MSCs) was evaluated. Materials and Methods: Aligned and random nanocomposite nanofibrous scaffolds were electrospun from polylactic acid (PLA), poly (vinyl alcohol) (PVA) and calcium carbonate nanoparticles (nCaP). The surface morphology of prepared nanofibrou...
