Abstract :

Biodegradable nanomaterials are currently designed to transport therapeutic or diagnostic agents through biological barriers.
The material properties of biodegradable nanofibers are extremely advantageous for drug delivery, and the use of drug-loaded
nanofibers has greatly increased over the past decade. Local delivery of pharmaceuticals by using nanofibers allows site-specificity
and requires a lower overall drug dosage with lower adverse side effects. Self-assembly, phase separation, and electrospinning can all
be used to successfully fabricate nanofibers with sizes perfectly within the same range of the fibers present in the native extracellular
matrix (ECM) (50–500 nm). Nevertheless, electrospinning has received the most attentions mainly due to that this procedure is
inexpensive, simple, and versatile, thus being effective for the production of a broad range of scaffold structures and materials.
Different drugs have been loaded onto various nanofibers, including those that are natural, synthetic, and copolymer, for various
medical applications. Pharmaceuticals can also be singly or coaxially loaded onto nanofibers to enhance clinical applications. In
particular, biodegradable drug-eluting nanofibers provide additional benefits to preventing wound adhesion and scar formation
because of their high surface area-to-volume ratios, high porosities, and three-dimensional open porous structures. This presentation
gives current research and breakthrough discoveries on the innovative application of biodegradable drug-loaded nanofibers that will
alter the clinical therapy of various diseases.
