NATURAL AND BIOINSPIRED NANOSTRUCTURED BACTERICIDAL SURFACES

Bacterial antibiotic resistance is becoming more widespread due to excessive use of antibiotics in healthcare and agriculture. At the same time the development of new antibiotics has effectively ground to a hold. Chemical modifications of material surfaces have poor long-term performance in preventing bacterial build-up and hence approaches for realising bactericidal action through physical surface […]

TRANSMISSION OF COVID-19 VIRUS BY DROPLETS AND AEROSOLS: A CRITICAL REVIEW ON THE UNRESOLVED DICHOTOMY

The practice of social distancing and wearing masks has been popular worldwide in combating the contraction of COVID-19. Undeniably, although such practices help control the COVID-19 pandemic to a greater extent, the complete control of virus-laden droplet and aerosol transmission by such practices is poorly understood. This review paper cited intends to outline the literature […]

WHAT IS THE EPA DOING TO APPROVE LONG LASTING DISINFECTION ANTIMICROBIALS?

A standard EPA-approved method does not currently exist for testing long-lasting efficacy (ability to kill or eliminate the target pathogen) against viruses on surfaces.  The EPA developed  a new standardized approach  to achieve the objective of this  by combining elements of ASTM 2197-17, ASTM 1053, and EPA’s “Protocol for the Evaluation of Bactericidal Activity of […]

Aerosol 101

Are Aerosols dangerous? • The air we breathe always contains solid particles or droplets and is therefore an aerosol • These aerosol particles can be from natural sources or man-made sources • Sometimes the particles are of type that, at sufficient concentration, are toxic to our body. • The organ in our body most sensitive […]
