Bacterial cellulose is a naturally occurring polysaccharide with numerous biomedical applications that range from drug delivery platforms to tissue engineering strategies. BC possesses remarkable biocompatibility, microstructure, and mechanical properties that resemble native human tissues, making it suitable for the replacement of damaged or injured tissues. In this review, we will discuss the structure and mechanical properties of the BC and summarize the techniques used to characterize these properties. We will also discuss the functionalization of BC to yield nanocomposites and the surface modification of BC by plasma and irradiation-based methods to fabricate materials with improved functionalities such as bactericidal capabilities.

Microgels/nanogels (micro/nanogels) are promising drug-delivery systems (DDS) because of their unique properties, including tunable chemical and physical structures, good mechanical properties, high water content, and biocompatibility. They also feature sizes tunable to tens of nanometers, large surface areas, and interior networks. These properties demonstrate the great potential of micro/nanogels for drug delivery, tissue engineering, and bionanotechnology. This mini-review describes the current approaches for the preparation and engineering of effective micro/nanogels for drug-delivery applications. It emphasizes issues of degradability and bioconjugation, as well as loading/encapsulation and release of therapeutics from customer-designed micro/nanogels.
