With the help of state-of-the-art equipment provided by the Massachusetts Institute of Technology MIT , the researchers were able to screen thousands of materials at the same time in a bid to identify new materials that had the right bacteria-fighting properties.

Morgan Alexander, with the University of Nottingham's School of Pharmacy, credited the MIT team with developing the technology that allowed researchers to narrow the search for the new class of polymers. The material has been compared by Britain's Wellcome Trust science funding initiative to the non-stick coatings on frying pans.

Alexander noted that medical devices are often given toxic coatings to kill bacteria, and added that materials such as silicone rubber weren't designed as biomedical materials.

Bacteria-resistant coatings -

Notwithstanding the ubiquitous nature of the problem of microbial colonization of material surfaces, this review focuses on the recent developments in antimicrobial surface coatings with respect to biomaterial implants and devices. In this biomedical arena, to rank the different coating strategies in order of increasing efficacy is impossible, since this depends on the clinical application aimed for and whether expectations are short- or long term.

Considering that the era of antibiotics to control infectious biofilms will eventually come to an end, the future for biofilm control on biomaterial implants and devices is likely with surface-associated modifications that are non-antibiotic related.

Abstract Bacterial adhesion and subsequent biofilm formation on material surfaces represent a serious problem in society from both an economical and health perspective. Publication types Research Support, Non-U.

Gov't Review. In developing countries the situation is worse. There is an increase in the need to protect surfaces from germs and microbes. The need is more widespread.

From surfaces, equipment and walls, to textiles and food, everything is susceptible to microbes, which ultimately find their way to human beings. It is not possible to always clean, disinfect or use strong chemicals on surfaces to prevent the growth of germs.

In this scenario, antimicrobial coatings seem to be the best option. It is a simple process of coating the surface with antimicrobial agents, leading to a more secure and long-term solution. Obtaining a surface that can hinder the growth of microbes can be attained through two methods.

The first method is a physical modification, which comprises material alteration and surface roughness. The second method involves chemical change. Chemical changes include grafting of polymers, superhydrophobic surfaces, use of nanomaterials and coatings.

These coatings include self-cleaning coatings and coatings with antimicrobial additives. The safety level, industry norms and the specific use of the coated object are kept in mind when choosing the most suitable antimicrobial coating. There is no specific test mentioned by the antimicrobial sector as a single test to prove the efficacy of antimicrobial coating.

However, several test methods have been developed by different organizations to meet industry standards. Some of these tests are coined by the American Society for Testing and Materials ASTM , American Association of Textile Chemists and Colorists AATCC , Japanese Industrial Standard JIS , and International Organization for Standardization ISO.

The tests help gauge the performance of an antimicrobial coating in combatting the growth and survival of microbes. These tests are designed for specific fields of use, material or antimicrobial technology. As a result, it is difficult to choose one method. However, an example of standards is ISO JIS Z for antibacterial coating by manufacturers.

Antifungal test methods are ASTM G21 or AATCC Method 30, Part III. Similarly, ASTM E is used to detect antimicrobial activity after one hour exposure, and ASTM E is used to detect the antimicrobial activity after 24 hours of exposure on textiles.

Also, ASTM G21 is used to determine resistance against black mold and fungus. Today, antimicrobial surface coatings find use in several consumer and industrial applications, apart from the healthcare sector, such as:. An essential requirement of antimicrobial coatings is in the medical field.

All healthcare facilities face the risk of HCAIs. Antimicrobial coatings help to reduce the spread of germs through common areas like switches, doorknobs, etc. Further, the coatings are used on catheters, surgical devices, medical electronics, medical instruments, trays, etc.

They are now even used for hospital fabrics, including gloves, surgical masks, wound dressing, bandages, woven hospital textiles and non-woven hospital textiles.

Innovation in the field has led to the use of these coatings in medical implants too. Antimicrobial coatings are useful for a variety of buildings like schools, office buildings, restaurants, public venues and residential buildings for long-term protection from disease-causing microbes.

They are also used vastly in maintaining the indoor air quality in air handling systems, like ventilation, heating, air-conditioning, ceilings and fans. The coatings are effective in combating mold growth and regrowth on various surfaces like automotive components, walls, ceiling pipes, etc. Antimicrobial coatings have made their way into the food sector as well, finding use in food processing units, dairy, large-scale production, as well as in the utensils and containers used in the process.

In the textile sector, they help provide durability, freshness and stain resistance to fabrics. As mentioned earlier, there is a widespread growth in the use of antimicrobial coatings for not only the industrial and healthcare sectors where they are most needed, but also for domestic use.

Following are some of the benefits of these coatings. First and foremost, these surface coatings protect against the growth of various microbes like bacteria, fungi, algae, mold, etc. Research has shown that the application of these coatings on surfaces inhibits the growth of different microorganisms.

A surface becomes an unfavorable environment for microbes to grow and survive as long as the coating is applied to it. It also leads to preventing staining, the presence of any bad odor, or degradation of the applied surface. The use of antimicrobial coatings on surfaces reduces the need for harsh cleaning agents and disinfectants required to deal with stubborn microbes in public facilities.

This gradually leads to a reduction in the environmental impact of using these cleaning agents in buildings, especially medical facilities. Consider the case of an office, school or hospital where there are a large number of people. There is a high probability of the spread of infections in such places.

The presence of an antimicrobial coating on surfaces helps to combat the spread of these infections or diseases to a large extent.

The coatings protect the high-volume trace points like doorknobs, switches, railings and furniture. Further, they contribute to cleanliness by decreasing the presence of bacteria and germs in the air.

Antimicrobial coatings help reduce maintenance costs. When the coating is applied on a surface, it prevents staining, discoloration, leeching or other factors that affect the look of the object.

It saves the extra financial burden and labor that would have been required for the upkeep or replacement of these objects. Protection from microbes coupled with the maintenance provided by antimicrobial coatings increases the general lifespan of objects, as they are protected against discoloration, odor and other damage caused by microbial activity.

The application of antimicrobial coatings not only protects surfaces but also contributes to the infrastructure standard as a whole.

The existence of these coatings enables organizations to provide a safer and cleaner environment for the people in it. The use of these coatings on surfaces carries a more profound message that organizations do care about the safety and atmosphere that they provide to people.

It certainly adds to the value of the building and its overall infrastructure. While there are enormous benefits of antimicrobial coatings, there are some drawbacks. The various risks associated with the use of the antimicrobial coatings on surfaces include the following:.

It has led to the Safe-by-Design concept, which emphasizes the need for designing a product eliminating hazardous material. It highlights the control of the release of antimicrobial elements from the coating. It could also be designed to target some specific microbes without harming the other bacteria.

Further, there is a need for using an appropriate production process that takes care of all the safety requirements. A study has suggested the treatment of hospital wastewater to stop it from affecting marine life. New technologies have evolved with various research in the field.

Polymers, safe bacteria-repelling surfaces, and other innovative technologies have been used to neutralize the adverse effects of antimicrobial coatings. Products are now being designed with safety, convenience and cost effectiveness as a priority.

Today, technology is used widely in the field of medicine with proper safety norms and utmost care. In the case of medical implants in a body, there is a high chance of bacterial infection. Also, it is difficult to remove and replace implants frequently.

It is well known that bacteria are living microbes that can be killed with the help of antibacterial agents, while a virus is a nonliving pathogen and cannot be killed but only deactivated.

Also, a virus has a negatively charged exterior membrane that can be destroyed by solvents, certain UV frequencies, heat, spikes, extreme positive charges, or metallic ion interference.
