Cellulose derived from Cladophora sp. algae exhibits exceptional surface area and high crystallinity. This novel biomaterial holds promise for various advanced applications.

Area of Science:

  • Biomaterials Science
  • Materials Chemistry
  • Algal Biotechnology

Background:

  • Cellulose is a versatile biopolymer with diverse applications.
  • Algal biomass represents an underutilized renewable resource.
