A low-pressure mercury-vapor discharge tube floods the inside of a biosafety cabinet with shortwave UV light when not in use, killing microbes on irradiated surfaces. Ultraviolet germicidal irradiation (UVGI) is a disinfection technique employing ultraviolet (UV) light, particularly UV-C (180–280 nm), to kill or inactivate microorganisms.
Disinfectant. Disinfection of a floor using disinfectant liquid applied using a mop. Levels of resistance of microbes to disinfectants. A disinfectant is a chemical substance or compound used to inactivate or destroy microorganisms on inert surfaces. [1] Disinfection does not necessarily kill all microorganisms, especially resistant bacterial ...
Microorganisms growing on an agar plate. Sterilization (British English: sterilisation) refers to any process that removes, kills, or deactivates all forms of life (particularly microorganisms such as fungi, bacteria, spores, and unicellular eukaryotic organisms) and other biological agents (such as prions or viruses) present in or on a specific surface, object, or fluid.

Bactericide. A bactericide or bacteriocide, sometimes abbreviated Bcidal, is a substance which kills bacteria. Bactericides are disinfectants, antiseptics, or antibiotics. [1] However, material surfaces can also have bactericidal properties based solely on their physical surface structure, as for example biomaterials like insect wings.
Antimicrobial. An antimicrobial is an agent that kills microorganisms (microbicide) or stops their growth (bacteriostatic agent). [1] Antimicrobial medicines can be grouped according to the microorganisms they act primarily against. For example, antibiotics are used against bacteria, and antifungals are used against fungi.
Turns out, the trusty kitchen appliance is actually pretty disgusting, according to a new study. Researchers swabbed 30 microwaves in homes, offices, and microbiology laboratories and found 747 ...
Antimicrobial peptides have been demonstrated to kill Gram negative and Gram positive bacteria, [1] enveloped viruses, fungi and even transformed or cancerous cells. [2] Unlike the majority of conventional antibiotics it appears that antimicrobial peptides frequently destabilize biological membranes , can form transmembrane channels , and may ...
Hand washing (or handwashing), also known as hand hygiene, is the act of cleaning one's hands with soap or handwash and water to remove viruses / bacteria / microorganisms, dirt, grease, and other harmful or unwanted substances stuck to the hands.
