Apparatuses of a biodegradable magnetic toilet seat cover and methods for manufacturing the same are provided. In one embodiment, a biodegradable magnetic toilet seat cover includes a bottom layer configured to contact with a toilet seat, where the bottom layer is made to prevent elements on the toilet seat from permeating to a skin of a user, a top layer configured to contact with the user, where the top layer is made to provide a comfortable touch to the skin of the user, and a middle layer configured to hold the bottom layer and the top layer together, where the middle layer is further configured to hold the biodegradable magnetic toilet seat cover to the toilet seat magnetically. The biodegradable magnetic toilet seat cover may additionally or optionally include an anti-splashing flap formed with polyvinyl alcohol or viscose spunlace non-woven film, and where the anti-splashing flap is configured to prevent elements from the toilet to reach the user.

Nitric oxide-releasing packaging membranes

Biodegradable composite membranes with antimicrobial properties consisting of nanocellulose fibrils, chitosan, and S-Nitroso-N-acetylpenicillamine (SNAP) were developed and tested for food packaging applications. Nitric oxide donor, SNAP was encapsulated into completely dispersed chitosan in 100 mL, 0.1N acetic acid and was thoroughly mixed with nanocellulose fibrils (CNF) to produce a composite membrane. The fabricated membranes had a uniform dispersion of chitosan and SNAP within the nanocellulose fibrils, which was confirmed through Scanning Electron Microscopy (SEM) micrographs and chemiluminescence nitric oxide analyzer. The membranes prepared without SNAP showed lower water vapor permeability than that of the membranes with SNAP. The addition of SNAP resulted in a decrease in the Young's modulus for both 2-layer and 3-layer membrane configurations. Antimicrobial property evaluation of SNAP incorporated membranes showed an effective zone of inhibition against bacterial strains of Enterococcus faecalis, Staphylococcus aureus, and Listeria monocytogenes and demonstrated its potential applications for food packaging.
