The novel and improved face mask materials with inherent virucidal activity not onlyreduces/nullifies the viral load via inhalation, but reduces the transmission from both the inhalation and contact routes by contributing to good hygienic practice thus reducing the impact of asymptomatic carriers and patients with low-grade disease in the community. This prevents the possibility for re-inhalation of carbon dioxide-rich air and gives comfort to the wearer. Variable enhancement of the virucidal, filtration and hydrophobic activities across multiple layers are achieved to suit different cohorts within the general populace as well asthe Healthcare system afflicted by the COVID-19 pandemic. Uniquely different types of face masks are custom-made with suitable degrees of enhancement of outer, middle and inner layers for different requirements of specified end-user populations utilizing commonly available, low-cost material. In addition to the above advantages, the present invention is fabricated of biodegradable materials at the same time it can be washed several times afterusage making it cost effective. It is also constructed in way that it can fit the face of the wearer perfectly without any spaces in-between. Further applications for this unique invention, combining nano-filtration with virucidal properties via use of nanotechnologyincludes, advanced filtration of artificial ventilator machines, air-purifiers, air-conditionerfiltration systems and Health care system usage as in bedding, scrub suits, clothing, etc. Theuse of germicidal properties would complement measures usually practiced for seasonalinfluenza and should also be considered for other diseases transmitted via inhalation route.

Appl.No 16894040 Applicant Bich Q. Tran Inventor Bich Q. Tran

A personal protection device includes one or two elongate members for engaging into the nostrils of the nose of a user. The elongate members each includes gridded ports for allowing air to pass through the elongate member when breathing in and for allowing air to exit via the elongate member when breathing out. Sensors are placed in the air flow pathway to detect pathogen presence, and the primary air filter is positioned in the elongate member. In yet other embodiments, a disposable version is disclosed. The eyewear can also be used as part of an extended reality system, and when game playing, particularized scents can be rendered to the nose to enhance the gaming experience. In another aspect, systems and methods protect against pathogen by sampling an environment of a travel path with a plurality of pathogen detectors along the travel path to detect a presence of one or more pathogens, wherein at least one detector includes a nano-sensor with receptacles to bind to the pathogens and wherein the nano-sensor changes resistivity, inductance or capacitance upon pathogen binding; directing air towards said pathogen detectors; contact tracing a user mobile device having a mobile identification (ID) carried by each user, wherein the mobile device comprises a memory storing mobile IDs of all devices within a predetermined radius of the user mobile device; and performing deep learning with a neural network receiving data from the pathogen detectors and to the user mobile device to detect a presence of one or more pathogens.
