A method of authenticating an item is disclosed which includes applying light to an item, wherein the item includes a random distribution of fluorescent particles disposed thereon, capturing one or more images from the item, generating a cryptographic pattern from the one or more captured images by a host processing system, communicating the cryptographic pattern to a remote processing system having a plurality of cryptographic keys in a database each uniquely associated with a corresponding item, comparing the cryptographic pattern with the plurality of cryptographic keys in the database, and communicating a positive evaluation for authentication to the host processing system if a match is found between one of the plurality of cryptographic keys and the communicated cryptographic pattern.

Image processing and authentication of unclonable functions

A whole-body or whole-room voluminous antiviral and antibacterial airborne disinfection system is disclosed which includes a sterilization chamber, including a nozzle disposed in the sterilization chamber, a tank disposed outside the sterilization chamber, the tank is adapted to hold a photosensitizer fluid of edible food dyes, a light source within the sterilization chamber adapted to flood the sterilization chamber with light; and a nozzle adapted to release the photosensitizer fluid aerosols and generate reactive oxygen species in a fog-like dispersion.

Antiviral and antibacterial disinfection aero-solution using edible food dyes

An apparatus for quantum-based physically unclonable functions is disclosed. The apparatus for quantum-based physically unclonable functions according to an embodiment of the present embodiment comprises a random nanostructure formed on a substrate by hydrothermal synthesis, wherein the random nanostructure emits a laser light of a predetermined pattern through the quantum activity of the random nanostructure.

Apparatus for quantum-based physically unclonable functions

A method of generating a physically unclonable function (PUF) for pharmaceutical authentication is disclosed which includes generating an edible (PUF), affixing the edible PUF onto a pharmaceutical in a random distribution, and generating a cryptographic key based on the randomly distributed and affixed edible PUF. The present disclosure generally relates to counterfeit measures, and in particular, to an arrangement concerning an edible unclonable function counterfeit measure.

Edible unclonable functions

A method of disinfection of a surface of a subject of harmful microorganisms including pathogenic bacteria and viruses upon visible light irradiation using a hybridized fluorescent silk is provided. The method includes placing a predetermined quantity of the hybridized fluorescent silk i) directly on to a skin surface of a subject; or ii) on a medium and then placing the medium on the skin surface of the subject. The method further includes applying light in the visible spectrum for a predetermined amount of time to the placed quantity of hybridized fluorescent silk, wherein the hybridized fluorescent silk is one of KillerRed, SuperNova, KillerOrange, Dronpa, TurboGFP, mCherry, or any combination thereof.

Light activated photoreaction via genetic hybridization of far-red fluorescent protein and silk

A method of inactivating harmful microorganisms of a filtration medium including pathogenic bacteria and viruses is disclosed which includes placing a predetermined quantity of a hybridized fluorescent silk on to a filtration medium, applying light for a predetermined amount of time to the placed quantity of the hybridized fluorescent silk, and passing a fluid through the medium, wherein the fluid is one of substantially air or substantially water, wherein the hybridized fluorescent silk is one of KillerRed, SuperNova, KillerOrange, Dronpa, TurboGFP, mCherry, or any combination thereof.

A photoelectric device is disclosed. The photoelectric device includes a first electrode, a second electrode, and an electrolyte disposed between the first electrode and the second electrode. The second electrode includes a transparent layer for allowing light to penetrate into the second electrode, an electron transport layer coupled to the transparent layer, and a genetically hybridized fluorescent silk layer as a photo-sensitizer coupled to the electron transport layer.
