Sistema de extrusión de biopolímeros naturales para la bioimpresión de hidrogeles usados en aplicaciones de ingeniería de tejidos

Abstract

Bioprinting, through the extrusion system of natural biopolymers for the manufacture of hydrogels, represents an advanced frontier in tissue engineering. This revolutionary process amalgamates the precision of additive manufacturing with the uniqueness of biopolymers derived from natural sources, such as starch and cellulose. The biocompatible essence of these materials offers crucial advantages in terms of interaction with living cells and their degradability, essential aspects for sustainability and biocompatibility in medical applications. The extrusion system becomes a key component by allowing the precise deposition of these biopolymers, creating three-dimensional structures with extraordinary fidelity and detail. This method stands out for its ability to generate complex architectures, imitating the microstructure of natural tissues. This innovative approach not only meets the fundamental requirements of biocompatibility and structural precision, but also paves the way for transformative medical applications. The possibility of printing functional tissues and organs opens new perspectives in regenerative medicine and pharmaceutical research. Furthermore, the biodegradable nature of the biopolymers used supports the search for more sustainable solutions in tissue engineering.
