The U.S. Department of Agriculture (USDA) announced on April 11, 2023, that its Agricultural Research Service (ARS) recently developed sustainable, machine-washable antimicrobial wipes that can be used at least 30 times for cleaning hard and nonporous surfaces. According to USDA, ARS researchers developed the antimicrobial wipes “by using raw cotton fiber that naturally produced silver nanoparticles inside the fiber in the presence of a silver precursor.” USDA states that the...

The Nanotechnology Industries Association (NIA) has posted a recording of its March 6, 2023, webinar on “Nano in Action: Antimicrobial Treatment.” The webinar explored a topic where relevance has been amplified by the COVID-19 pandemic, but that has long been on the to-do list of the public building and transport sectors. Subjects covered included the current cleaning and sanitation protocols of public spaces; the kind of nano-based solutions available to meet this need; and how...

The International Organization for Standardization (ISO) recently published ISO/TS 23650:2021, “Nanotechnologies — Evaluation of the antimicrobial performance of textiles containing manufactured nanomaterials.” ISO states that the standard specifies the antimicrobial performance assessment method for textiles containing manufactured (metals/metal oxides) nanomaterials. The textiles in the standard include fabric, yarn, and fiber in which manufactured nanomaterials are used during the...

On October 2, 2019, the U.S. Environmental Protection Agency (EPA) published a notice in the Federal Register announcing the availability of, and soliciting public comment on, the draft document entitled “Antimicrobial Performance Evaluation Program (APEP) A (Draft) Risk Based Strategy to Ensure the Effectiveness of Hospital-Level Disinfectants” (draft Strategy).  EPA states that “The draft Strategy provides a framework to ensure that registered hospital-level disinfectants...

On June 21, 2018, during the U.S. Environmental Protection Agency’s (EPA) Office of Pesticide Programs (OPP) webinar, EPA discussed the new draft risk-based strategy for ensuring the performance of public health antimicrobial products and announced the intended replacement of the former Antimicrobial Testing Program (ATP) with the new Antimicrobial Product Evaluation Program (APEP).  Comments on the draft risk-based strategy may be submitted to EPA until July 16, 2018. Public health...

On September 8, 2015, the Environmental Protection Agency (EPA) announced that it will host a Disinfection Hierarchy Stakeholder Workshop and corresponding webinar on October 7, 2015, from 8:30 a.m. – 5:00 p.m. (EDT).  The “disinfection hierarchy” describes the descending order of susceptibility of classes of microorganisms to antimicrobial chemicals.  Demonstrated efficacy against a representative organism would support a manufacturer’s claims against more...

An undergraduate fashion design student, a fiber science professor, and a postdoctoral researcher at Cornell University in New York have teamed up to design what may very well be the world’s first garment “that can prevent colds and flu.” According to a May 1, 2007, news release, the three collaborators produced a dress from cotton fabrics that had been coated with silver nanoparticles. Silver, of course, is a well-known antimicrobial. Cotton fibers were positively...
