The use of synthesized inorganic materials in nanotechnology poses great danger towards people, raising the demand for organic materials to be developed instead. Cellulose nanofibers, which have unique properties and organic origin, have been seen as a great potential for various applications. Banana is an important fruit crop in the Philippines, and in exchange of its great mass production is the production of waste, such as its peels. This study synthesized cellulose nanofibers (CNF) from Musa acuminata x balbisiana (Cardaba) banana peels as an antibacterial and blood coagulating agent. Banana peels were collected, cleaned, steam exploded under pressure by autoclaving, bleached and then acid hydrolyzed to produce CNF. Scanning Electron Microscopy (SEM) was done to evaluate the surface morphology of the CNF. Antibacterial assay was assessed via paper disc diffusion technique. Blood clotting time was monitored using the standard slide method. SEM images showed fibers with diameters ranging from 20nm to 43nm. Data suggests that cellulose nanofibers were successfully developed. Results further revealed that CNF exhibits an antibacterial activity against S. aureus with a mean diameter of 9.29 mm zone of inhibition. Data indicates the potential of Cardaba peelings as organic material for medical applications.
