Catalyst-free crosslinking modification of nata-de-coco-based bacterial cellulose nanofibres using citric acid for biomedical applications

Bacterial cellulose (BC) has gained attention among researchers in materials science and bio-medicine due to its fascinating properties. However, BC’s fibre collapse phenomenon (i.e., its inability to reabsorb water after dehydration) is one of the drawbacks that limit its potential. To overcome thi...
