Summary: Bacterial cellulose (BC), produced by microorganisms, can be modified to produce different cellulosic formats. BC has advantages for biomedical applications such as easy moldability, high biocompatibility, and tailoring ability. Its hydroxyl residues and nanoporous morphology make it ideal for wound healing. This article discusses the characteristics of different BC structures, recent advances in BC composites, and the development of antimicrobial BC and drug delivery systems.

Summary: A multifunctional dressing based on bacterial cellulose (BC) deposited with a tannic acid/Cu2 + ion/Mg2 + ion (TCM) complex film is developed in this study. The TCM complex exhibits robust interfacial adhesion and good photothermal properties to effectively eradicate bacteria in the wound area under near-infrared (NIR) irradiation. The released Cu2 + and Mg2 + ions from the TCM complex are favorable for endothelial cell proliferation, migration, and tube formation in vitro, promoting angiogenesis and collagen deposition in bacteria-infected wounds.

Summary: The study investigated the caffeine content and phenolic profile of different types of teas and coffees with two successive extractions. Green tea showed high flavanol content in the second extraction, while mate tea's phenolic acid content increased. Black tea had the highest caffeine content in both extractions, and water was the most effective solvent in most cases for extracting these compounds.

Summary: This study introduces a novel ex situ modification method for bacterial cellulose (BC) polymer, significantly enhancing its water absorption capacity through a single and cost-effective crosslinking process. The optimized crosslinked BC showed superior water capacity compared to modern commercial dressings, making it a potentially valuable material for super-absorbent dressings designed for chronic wounds.

Summary: In this study, nano-gold chitosan-bacterial cellulose (CBC-Au) was successfully fabricated via a facile in-situ method using spent ground coffee (SGC) in a kombucha consortium. The CBC-Au showed better antimicrobial activity than BC and displayed good biocompatibility performance, indicating its potential use as a medical scaffold.

Summary: The delayed healing of wounds among people with diabetes is a severe worldwide problem. Hyperglycemia and increased levels of free radicals are the major inhibiting factors of wound healing in diabetic patients. Plant extracts rich in polyphenols can be an effective agent for wound healing, but optimization of the extraction protocol is needed to ensure efficacy.

Summary: This study evaluated the antioxidant capacity of liposomal formulations containing green coffee and medium roasted coffee extracts in aq. and MeOH, showing that these formulations have higher antioxidant activity compared to individual extracts. The HPLC analysis revealed the presence of various phenolic compounds in the coffee extracts, with methanolic extracts demonstrating the highest caffeine and chlorogenic acid content. The results suggest that the liposomal coffee extract formulations have strong antioxidant properties, paving the way for future studies on their potential applications.
