The present subject matter includes novel chemical formulations having antimicrobial, antifungal, antiseptic, and related effect in a wide range of applications for treating or preventing infections as well as treating various surfaces that may become tainted with infectants. In some embodiments, the formulation includes isoamyl hexanoates and at least one of propanoic and/or isobutyric acid.

A method for in situ production of antimicrobial filtration membranes that uses self-assembly of surfactants such as block copolymers as a template. The mesophase structure (for example hexagonal or lamellar) can be determined, and membrane pore size can be controlled in the nanometer range, by changing the block copolymer and the amounts of the components such as the block copolymer, aqueous solution, monomer, crosslinker, and initiator. The monomer phase cures in the template and there is no need for organic solvents and coagulation bath or other post-modification. As-synthesized membranes were found to have pore sizes with a narrow size distribution in the range of 3-4 nm with a molecular weight cutoff of 1500 g/mol and displayed both excellent fouling resistance and high permeance of water, vastly outperforming a conventional NIPS UF membrane. The monomer can comprise a quaternary ammonium group so that the membrane is antibacterial. The block copolymer can comprise hydrophilic blocks which form the surfaces of the membrane pores, rendering them hydrophilic.

The present invention relates to an ovitrap (10) and novel method of controlling mosquito populations comprising the use of light (20) to create a photo stimulus, causing mosquito larvae (102) to move from a location (Va), where gravid mosquitoes have deposited their eggs, in a direction away from the light, to a location (Vb). where they are trapped and killed. The ovitrap utilises this behaviour to more effectively capture and kill larvae. The ovitrap comprises a container (12), a cover (14), and a means (16) for dividing the container (12) into two regions (101; 102), which in use are filled with water, and which communicate via an opening (26) such that a volume (Vb) below the means (16) defines a larvae (102) trapping region, and a volume (Va) above the means (16) defines an egg (101) receiving region. A light source (20) is mounted above the container (12) and is positioned to direct light downwards at a water surface (92), such that when the light is turned on, it creates a photo stimulus, and the larvae (102) respond by moving in a direction away from the light, from the volume above (Va) into the volume below (Vb) via opening (26). A gating mechanism (18) opens and closes the opening (26) when the light is respectively turned on and off, such that the larvae are trapped in the volume below

This invention relates to compositions and methods for cleaning, disinfection, and sterilization of hard, soft, and porous surfaces, equipment, human skin, tissues, food and vegetable surfaces, and other media which are contaminated with microorganisms such as bacteria, viruses, yeast, and molds. Particularly relevant is the microbial environment whereby bacterial communities can generate three-dimensional polymicrobial Extracellular Polymeric Substances, or EPS, biofilm communities supported by an aggregation of microorganisms growing on a substrate layer, substantially degrading the antimicrobial performance of typical cleaners, disinfectants, and sterilizers. There is great need for a composition that will reliably eradicate microorganisms across a broad spectrum, particularly polymicrobial EPS communities shrouded by self-generated biofilm layer. Such a composition is disclosed herein. The invention discloses new compositions, and methods for formulation of compositions, of weak acids, surfactants, and glycol monoesters, which achieve a level of eradication such that when tested following application, no surviving microorganisms remain. All compositions and methods disclosed herein have the further benefit of their ingredients being classified by the US Food and Drug Administration (FDA) as GRAS, or Generally Regarded As Safe for use on food and food contact surfaces; and the embodiment of the claimed invention herein contains 95% USDA Certified Biobased content, and is accepted to the USDA BioPreferred® Program.
