Dangers of Mould and Mildew

Mould and mildew are much worse than most people believe it is. It can certainly be frustrating when you spot soft or hard surfaces covered with mould because not much can be done to stop it once the spores have taken hold. You may be able to keep it from spreading, but the places where it has already grown are compromised forever.

Both of which can be the cause of serious health complications, and potentially death. Colonies of Penicillium fungi.

Why do we rely on our bodies for viral and bacterial infections?

We rely on our bodies and vaccines to create viral antibodies to fend off sickness. There are antiviral drugs, but with so many variations of cold and flu bugs, it is often impossible to target specific strains.

Is antimicrobial a specialty?

As with antibiotics, antimicrobial products can be specialized , or they can work on a multitude of different microbes. However, the most important distinguisher that results in a product being defined as antimicrobial, and not an antibiotic, is the use outside of a body. Antimicrobial efforts are always concerned about materials.

Is a sponge an antibiotic?

Products such as textiles, plastics, metals, coatings and more can be treated with additives to become antimicrobial, but if the molecule is ingested to fight bacteria, then it is, in fact, an antibiotic. The sponge on the right is treated with Ultra-Fresh, an antimicrobial additive that inhibits fungal growth in the sponge.

What is an antimicrobial surface?

Such surfaces are becoming more widely investigated for possible use in various settings including clinics, industry, and even the home. The most common and most important use of antimicrobial coatings has been ...

How can antimicrobial activity be imparted onto a surface?

Antimicrobial activity can be imparted onto a surface through the grafting of functionalized polymers, for example those terminated with quaternary amine functional groups, through one of two principle methods. With these methods—“grafting to” and “grafting from”—polymers can be chemically bound to a solid surface and thus the properties of the surface (i.e. antimicrobial activity) can be controlled. Quaternary ammonium ion-containing polymers (PQA) have been proven to effectively kill cells and spores through their interactions with cell membranes. A wealth of nitrogenous monomers can be quaternized to be biologically active. These monomers, for example 2-dimethylaminoethyl methacrylate (DMAEMA) or 4-vinyl pyridine (4-VP) can be subsequently polymerized with ATRP. Thus antimicrobial surfaces can be prepared via “grafting to” or “grafting from” mechanisms.

Why are nanoparticles used in antimicrobial coatings?

What is the antimicrobial activity of dimethyloctadecyl?

The quaternary ammonium compound Dimethyloctadecyl (3-trimethoxysilyl propyl) ammonium chloride (Si-QAC) has been found to have antimicrobial activity when covalently bonded to a surface. Many other quaternary ammonium compounds are known to have antimicrobial properties (e.g. alkyldimethylbenzylammonium chloride and didecyldimethylammonium chloride). These last two are membrane active compounds; against S. aureus the first forms a single monolayer coverage of the S. aureus cells on the outer membrane, while the second forms a double monolayer. This leads to cell leakage and total release of the intracellular potassium and 260 nm-absorbing pools in this order.

How to prevent bacteria from growing on surfaces?

A main way to combat the growth of bacterial cells on a surface is to prevent the initial adhesion of the cells to that surface. Some coatings which accomplish this include chlorhexidine incorporated hydroxyapatite coatings, chlorhexidine-containing polylactide coatings on an anodized surface, and polymer and calcium phosphate coatings with chlorhexidine.

What is the ability to combat a certain type of organism?

Selectivity refers to the ability to combat a certain type or class of organism. Depending on the application, the ability to selectively combat certain microorganisms while having little detrimental effect against others dictates the usefulness of a particular antimicrobial surface in a given context.

What is chromogranin antifungal?

A chromogranin A-derived antifungal peptide (CGA 47–66, chromofungin) when embedded on a surface has been shown to have antifungal activity by interacting with the fungal membrane and thereby penetrating into the cell. Additionally, in vitro studies have demonstrated that such an antifungal coating is able to inhibit the growth of yeast Candida albicans by 65% and completely stop the proliferation of filamentous fungus Neurospora crassa.
