Abstract
Certain metal nanoparticles and essential oils have been found to have antibacterial properties. We explored their use as additives to alginate biofilm for fruit/vegetable preservation. Physical properties such as UV transmittance, solubility, swelling, and oil/water permeability of the alginate biofilm with and without different additives were investigated. We also focused on learning about Atomic Force Microscopy (AFM), a high-resolution imaging technique for future use in material studies. Forensic samples such as cat, dog, and human hairs, as well as ink samples, were chosen to practice the operation of the AFM. Forensic samples were chosen because they require minimal sample preparation. Various ways of sample preparation for the study of metal nanoparticles with AFM, including thermal wax and spin coating, were tested on copper and zinc oxide particles prepared for use as additives to the biofilm. The benefits and challenges of the AFM, as well as possible future research on alginate biofilm, will be discussed.
