Nanocellulose has a wide range of applications in the biomedical field, and its unique properties make it an important biomaterial.The following are the main applications of nanocellulose in the biomedical field: 1. Drug delivery and release system: As a drug carrier, nanocellulose can wrap drug molecules in its nanostructure to form a nanocellulose-based drug delivery system.This system can improve the stability of the drug, prolong the blood concentration time and reduce the drug dosage, thereby enhancing the therapeutic effect of the drug.2. Wound healing and dressings: Nanocellulose can be used to prepare biodegradable dressings to promote wound healing and wound repair.Nanocellulose's high surface area and biocompatibility make it an ideal wound dressing material, helping to maintain a moist environment, promote regeneration and prevent infection.3. Biosensors: Nanocellulose can be used to make
