Bactericidal Surfaces

Even in the absence of light a decrease in cell growth was observed compared to unmodified BC. These materials are recommended for use as bactericidal surfaces in medical, healthcare, and hygienic applications [60]. 

Common Commercial Use Used as a solvent and a dehairing agent, in the manufacture of pharmaceuticals, dyes, insecticides, bactericides, surface-active agents, and textile specialties, and as an intermediate in the synthesis of rubber accelerators. 

Chloroform also will react with amines to form quaternary ammonium salts, which are used as bactericidal surface-active agents. It also will react with hydrazine to form dimethyl hydrazine and tetramethyl hydrazine, both used as rocket fuels [158,159],... 

As an example, a product claiming to be a hospital bactericide, active on surfaces, has to first pass the basic bactericidal suspension test, then the bactericidal suspension test for the medical area, and, finally, the bactericidal surface test in this area.

In this context, this work aims to compare the antibacterial efficiency of Ag and Cu in a Ti02 matrix to find the optimal content required to produce bactericidal surfaces, i.e. with a relative efficiency of 100%. The same CVD reactor has been used to prepare the samples. The film thickness was generally lower than 300 nm so as not to change the appearance of substrate.

They readily dissolve metal oxides and are effective metal surface cleaners and fluxes (see Metal surface treatments). They also have bactericidal and fungicidal properties (74). However, the main commercial appHcation among monofluorophosphates is of sodium monofluorophosphate ia dentifrices. 

The objective in packaging cool sterilized products is to maintain the product under aseptic conditions, to sterilize the container and its Hd, and to place the product into the container and seal it without contamination. Contamination of the head space between the product and closure is avoided by the use of superheated steam, maintaining a high internal pressure, spraying the container surface with a bactericide such as chlorine, irradiation with a bactericidal lamp, or filling the space with an inert sterile gas such as nitrogen. 

Ethanol (CH3CH2OH) is widely used as a disinfectant and antiseptic. The presence of water is essential for activity, hence 100% ethanol is ineffective. Concentrations between 60 and 95% are bactericidal but a 70% solution is usually employed for the disinfection of skin, clean instruments or surfaces. At higher concentrations, e.g. 90%, ethanol is also active against most viruses, including TUV. Ethanol is also a popular choice in pharmaceutical preparations and cosmetic products as a solvent and preservative. 

The first draft (finished in 1993 and revised in 1995) describes a test method for determination of the bactericidal activity of a chemical disinfectant applied to a contaminated surface under laboratory conditions ... 

Test Method. Due to the fact that there does not yet exist an official method for the investigation of the bactericidal activity of surfaces an adequate method had to be developed ... 

On a related theme, we can take advantage of the diffusion of molecules incorporated into a polymer to its surface. Thus we can blend lubricants, bactericides, and antiblock agents into polymers, which slowly exude to the surface where they perform a useful role. 

Gramicidin decreases the surface tension of aqueous solution77. The bactericidal and hemolytic properties of gramicidin were destroyed by heat but the surface tension depression was not changed. 

After the binding of the pathogen to the neutrophil surface via these receptors, the neutrophil must respond by activating its bactericidal arsenal. This activation is achieved through the occupancy of receptors, which trig-... 

The formation of antibodies is only one mechanism by which an animal may protect itself from substances or microorganisms that are potentially harmful. A mechanical protection against infection is provided by the presence of an intact skin surface and membranes together with the secretion of mucus from many internal membrane surfaces. The acids secreted by the stomach and skin have a bactericidal effect as does the presence in many body fluids of certain enzymes, particularly lysozyme.
