Hydrogen Peroxide is a chemical used in bleaches, dyes, cleansers, antiseptics, and disinfectants. In a concentrated form, it is toxic and irritating to tissues.
Since the Covid-19 pandemic began last year, face masks and other personal protective equipment have become essential for health care workers. Disposable N95 masks have been in especially high demand to help prevent the spread of SARS-CoV-2, the virus that causes Covid-19.
In a recent study published in Antioxidants, researchers evaluated the use of antioxidants as potential adjuvants for the treatment of COVID-19.
Aerospace giant Boeing tested two kinds of ionization technologies — like those widely adopted in schools hoping to combat covid — to determine how well each killed germs on surfaces and decided that neither was effective enough to install on its commercial planes.
In a recent review article published in the Science of The Total Environment journal, a group of Polish researchers discussed the different transmission routes of the severe acute respiratory coronavirus 2 (SARS-CoV-2), the virus responsible for the coronavirus disease 2019 (COVID-19). In their work, the researchers focused on the extent of SARS-CoV-2 survival in the environment, particularly in sewages and contaminated surfaces.
Last summer, Global Plasma Solutions wanted to test whether the company's air-purifying devices could kill covid-19 virus particles but could find only a lab using a chamber the size of a shoebox for its trials. In the company-funded study, the virus was blasted with 27,000 ions per cubic centimeter.
The COVID-19 pandemic has cast a harsh light on the urgent need for quick and easy techniques to sanitize and disinfect everyday high-touch objects such as doorknobs, pens, pencils, and personal protective gear worn to keep infections from spreading.
Is there a way to chemically manipulate small, confined areas on cellular surfaces? Scientists have developed a microfluidic probe to send a flow of free radicals on live cells and track the outcome using fluorescence imaging.
A new study describes the identification of new compounds from a library, with inhibitory activity against several coronaviruses. This study shows the utility of this method, besides identifying compounds that not only inhibit viral shedding in SARS-CoV-2 cultures, but have an immunomodulatory effect that may be useful in mitigating the damaging cytokine storm typical of severe or critical COVID-19.
Researchers at Rutgers School of Dental Medicine have found evidence that two types of mouthwash disrupt the COVID-19 virus under laboratory conditions, preventing it from replicating in a human cell.
Texas Biomedical Research Institute received two Department of Defense's (DoD) Defense Health Agency subcontracts to assess the efficacy of surface coating and aerosolized decontamination technologies to combat SARS-CoV-2 and other respiratory pathogens on surfaces and in the air.
Several processes in the human body are regulated by biochemical reactions involving hydrogen peroxide (H2O2).
A Mason Engineering researcher has discovered that artificial microswimmers accumulate where their speed is minimized, an idea that could have implications for improving the efficacy of targeted cancer therapy.
Those with asthma are experiencing less asthma control related to an increase in using household disinfectants -- known asthma triggers -- because of COVID-19, according to a survey co-conducted by University of Illinois Chicago researchers.
Chemical manufacturers frequently use toxic solvents such as alcohols and benzene to make products like pharmaceuticals and plastics.
A new preprint reports the efficacy of two repurposed drugs that could be useful against SARS-CoV-2 when supplemented with zinc.
With a name like glucose-6-phosphate dehydrogenase deficiency, one would think it is a rare and obscure medical condition, but that's far from the truth.
Researchers have found that oxidative stress and neurotoxicity biomarkers increased in tadpoles exposed to synthetic SARS-CoV-2 spike protein peptides.
Researchers at the University of Washington show that methylene blue (MB) and light can decontaminate masks and respirators by inactivating three tested coronaviruses without compromising integrity. The method is effective, low-cost, and does not require specialized equipment, making it applicable in any setting.
A variety of measures are necessary to prevent the spread of the coronavirus SARS-CoV-2 in hospitals and nursing homes. It is particularly important to develop an appropriate strategy to protect healthcare workers from airborne transmission.
Scientists at UC Davis Health have discovered that an enzyme in the colon lining releases hydrogen peroxide (H2O2) - a known disinfecting compound- to protect the body from gut microbes.
