WHERE CAN ANTIMICROBIAL COATINGS BE USE?
A microorganism can survive 4-6 days when the suitable conditions are found on the packaging packages. This makes it important to clean the packaging, common areas, medical devices and medical apparel.
Today, antimicrobial packaging, which is used naturally to increase the quality and safety of food, is gaining importance. As reported by the World Health Organization (WHO), more than 200 diseases from cancer to diarrhea have been reported to be caused by hazardous foods containing chemicals or microorganisms such as bacteria, viruses and parasites. It is estimated that approximately 600 million people (almost 10% of the global population) get sick after contaminated food intake, resulting in 420,000 deaths each year .
Packages with antimicrobial activity do microbial growth by reducing the rate of microorganism growth or extending the lag period. Thus, with the antimicrobial packaging technology, microorganisms and pathogens that cause food spoilage are neutralized and spoilage is prevented, and the shelf life of the food is extended. In addition, since the growth of these organisms on the products waiting on the shelves will be prevented, the problems threatening the health of the consumer during the contact with the packaging will be eliminated.
Hospital infections are one of the most important problems of our age. These infections are those that develop 48-72 hours after the admission of patients who are not in the incubation period at the time of admission to the hospital, or although they develop in the hospital, sometimes they may occur within 10 days after the patient is discharged. Although every 100 people hospitalized, depending on the units, 3-10 people wait for recovery, some of the events such as the death or even loss may occur as a result of some infection. as with all other respiratory viral infections, there is a risk of transmission of the virus, especially when touching the surfaces of the patient's hand, such as the door handle, stair railing. Antimicrobial coatings will be prevented with antimicrobial coatings on surfaces where we can frequently encounter microorganisms such as doors, window handles, taps, and staircase handle that people frequently contact in hospitals.
Medical clothes (gloves, masks and intensive care clothes) are designed to prevent infections by creating a barrier between sterile and non-sterile areas and minimizing the transmission of viruses to patients and the exposure of health personnel, especially blood-borne pathogens. The gaps in the masks that are used today are wide enough for a virus to pass through. Covering these gaps with an antimicrobial film is important in terms of both protecting the wearer from a momentary reaction and against microorganisms that can survive in the long term. Thanks to the antimicrobial coatings to be made on medical clothes such as gloves, mask, intensive care clothes, organisms such as viruses, bacteria, fungi from outside can be prevented from staying on these products.
