Synthesizing silver nanoparticles onto toilet seat covers using and This is achieved by fastening. 10 State of the Art Toilet hygiene plays a role in protecting public health and preventing the spread of infectious diseases. It plays a vital role in prevention. Toilets are breeding grounds for microorganisms. These are areas and therefore require regular cleaning. Good toilet hygiene is essential. It prevents the spread of waterborne and foodborne diseases such as dysentery, cholera, and hepatitis A. In addition, clean and hygienic toilets make individuals feel comfortable and safe. It helps them feel better, which improves their overall quality of life. World Health Organization According to the organization, unhygienic toilet conditions harm the health of millions of people every year. This leads to life-threatening diseases. Therefore, attention to toilet hygiene is crucial. 20 It is extremely critical for individual health and societal well-being. Unhygienic toilets can cause serious health problems and environmental pollution. Such toilets, especially in crowded places, can spread infectious diseases. It accelerates the process. For example, bacteria like E. coli and Salmonella found in unhygienic conditions. Bacteria can cause health problems such as diarrhea and food poisoning. Also, 25 Viruses like norovirus can easily spread from contaminated surfaces and cause outbreaks. That's possible. Unhygienic toilets also cause bad odors and an unpleasant environment. This creates a risk for people to avoid these areas and put their health at risk. This can be the reason. Lack of hygiene in public spaces can lead to widespread outbreaks of disease. This also creates the conditions for its emergence, which places a huge burden on health systems. 30 It creates. Western-style public toilets are quite risky areas in terms of health and hygiene. Some This is one of the first steps to take to stop specific epidemics. Personal 2 also in terms of preventing the spread of bacterial and viral-based diseases Toilets are target points. Public toilets are a concern in society due to hygiene problems. Some individuals who use toilets relieve themselves by stepping on them instead of sitting down. It is known to eliminate this problem. Moreover, this situation is not only valid for our country, but also... This has also been included in the international literature (Wu et al., 2019). According to studies in this field, 5 Dermal, small intestinal and vaginal pathogenic microorganisms can accumulate on the surfaces of public toilets. The presence of organisms has been demonstrated (Flores et al., 2011). Also in public toilets... One of the biggest problems encountered is men urinating while standing. This is due to the spreading of urine on and around the toilet surface. In this case, the urine... The pathogenic microorganisms found pose a serious problem. Also, 10 the pressure of the water coming out of the toilet after flushing following defecation As a result, these microorganisms splatter onto surfaces and even outside the toilet bowl. This is observed. According to a study conducted in the People's Republic of China, in society... 16.2% of individuals relieve themselves by stepping on the toilet seat instead of sitting on it. It has been reported that 43.9% of people do not close the toilet lid and do not flush (Wu et al., 15 2019). Today, various measures are taken to ensure hygiene in public toilets. This is done using a single device placed on the toilet seat. One of the most common applications is to place a single device on the toilet seat. These are disposable paper liners. These liners create a barrier between the user's skin and the toilet surface. It aims to reduce the risk of contact-borne transmission by creating a barrier. However, 20 Current paper toilet seat covers only provide physical protection, It does not possess antimicrobial, antiviral, or antifungal properties. This situation affects the covering. limiting its capacity to completely prevent the spread of microorganisms and This leads to inadequate efforts in making surfaces hygienic. Another current hygiene practice is the use of disinfectant sprays or wipes. This is how it is used. Users clean the toilet surface with solutions containing alcohol or disinfectant. It attempts to ensure hygiene by cleaning. However, these methods are easy to use. This is impractical in terms of requiring individuals to constantly carry disinfectant with them. This also requires a certain contact time for disinfectants to be effective. Hearing this leads to a loss of time during the process. This also means that public toilets are 30 It does not align with the need for quick use. In recent years, various technologies have been developed for hygienic toilet systems. For example, automatic toilet seats or systems that provide disinfection with UV light are some 3 They are used in modern facilities. However, these solutions are expensive due to their high costs. It has not become widespread and accessible to the general user base. In addition, systems containing mechanical or electronic components require maintenance. It also carries disadvantages in terms of long-term sustainability. Therefore, The need for low-cost, portable and user-friendly hygiene solutions continues. 5 is doing. The limitations and inadequacies of current technological solutions, the toilet seat used The inability of the coverings to completely prevent the spread of microorganisms, their use Its impracticality in terms of ease of use and the fact that it causes a waste of time, mechanical or systems containing electronic components are costly and require maintenance, for example. For these reasons, an improvement is needed in the toilet seat cover field. It has been made. Brief Description and Objectives of the Invention The invention describes a toilet seat with antimicrobial, antiviral, and antifungal properties. It is the coating. In-situ synthesis of silver nanoparticles is achieved using silver nitrate (AgNO3) solution. cellulose-based paper toilet seat covers are produced in situ with the help of light sources. It is synthesized on the surface. After this application, the paper used in toilet bowls... This ensures that the coverings acquire antimicrobial, antiviral and antifungal properties, and A significant hygiene problem is prevented. The toilet seat in question is 20 The cover has a non-slip surface on the inner side that contacts the toilet bowl, and a waterproof surface on the outer side. There is a surface. One aim of the invention is to achieve effective distribution of silver nanoparticles by homogeneous distribution. The aim is to obtain an antimicrobial property. For this purpose, an in- Silver nanoparticles were homogeneously coated using the in situ method. 25 Another aim of the invention is to obtain a toilet seat cover with non-slip properties. The purpose is to ensure the toilet seat cover is non-slip. The surface of the cover that comes into contact with the lid has a mini-layer that provides anti-slip properties. Cubic polymeric agents are coated. This surface layer is made from a separate material. It is being prepared and 30 by adding an antimicrobial, antiviral and antifungal layer. is obtained. The application method is suitable for cellulosic and polymeric materials. It contains chemicals that facilitate adsorption. 4 Additionally, another purpose of the invention is to create a waterproof toilet seat. The goal is to create a cover.
