Solution Blow Spinning: An Emerging Nanomaterials-Based Wound-Care Technology

Abstract

Application of one-dimensional nanofibers have witnessed exponential growth over the past few decades and are still emerging with their excellent physicochemical and electrical properties. The driving force behind this intriguing transition lies in their unique high surface-to-volume ratio, ubiquitous nanodomains, improved tensile strength, and flexibility to incorporate deliberate functionalities required for specific and advanced applications. Besides numerous benefits, nanomaterials may adversely interact with biological tissues and potentially be cytotoxic and carcinogenic. However, precisely engineered design can outperform the risk with myriad benefits. Wound care technologies are evolving, and products involved in wound care management have a yearly market value of $15–22 billion. Solution blow spinning (SBS) is a facile technique to synthesize biocompatible nanofibers with scalable processing variables for multidirectional biomedical applications. SBS is feasible for a wide range of thermoplastic polymers and nanomaterials to fabricate nanocomposites. This review will focus on the relevance of SBS technology for wound care, including dressings, drug delivery, tissue engineering scaffolds, and sensors.
