Germs have always been a problem for individuals since humanity came into being. Almost every type of common disease occurs because of the germs found in the environment. People do whatever they can to avoid the destructive germs in their homes and keep their family and loved ones protected by using sanitizers etc.
A new technique in paint manufacturing can certainly help people in creating their homes germ free. Not only homes, any surface whereby such paints will be used can become practically germ free surfaces. Paint analysts have made a type of paint which has silver coating nanoparticles in it. It has been scientifically tested that surfaces that have silver coating keep off germs. That is why every medical and surgical instruments go through the process of silver coating.
The silver nanoparticles which are being added in paints have been proven to exterminate bacteria as well as other kinds of germs. Such kind of paints will be very helpful in coating the hospital surfaces and countertops to evade bacterial growth. It has been proved by the CDC or the Unite States Centers for Disease Control and Prevention that nearly more than a million people contract diseases from hospitals every year. The silver coating in itself is an excellent bacteria killer and silver nanopartcles in theory are ideal in fighting off the minutest kind of microbes. With all of the studies which have been done, this silver coating hasn't shown any negative effects on human health.
A few researchers aren't so thrilled about using silver nanoparticles in paints and say that not enough research has been undertaken. According to these researchers, the silver in these paints eliminates good and even bad microorganism and this might have a harmful effect in the future. These researchers also have asserted that there should be a level of restriction that specifies the amount of silver nanoparticles to be used in such products.
A lot of researchers have proven this silver coating of paint on E. Coli and other forms of bacteria. The experiment consisted of a glass surface together with a coat of paint on it. The surface with the paint displayed no bacterial growth and the surface area without the silver coating paint had bacterial growth found on it. These researches has also shown that germs is unable to form a resistance against the action of silver present in these kinds of paints and thus, such paints will definitely kill the bacteria present around it. The size of the
silver coating nanoparticles also has to be viewed as changing the size changes the shade of the paint.
Today a lot of research is being carried out to find out whether such paints have any negative effects on human health. They also need to see the time duration such paints can retain their bacteria killing properties. Present results suggest that the time period is of three-years but with more research this time duration may also be increased. Most people are still not comfortable with using specialty coatings like silver based products but in the future, such paints will be surely made available to the consumer market.
Prototype Modeling - An Important Step For Manufacturing Processes In The FutureComputers are the main stay of our highly technological civilization. It is because of the creation of computers that we have been able to progress globally. Computers have made our lives easier by providing automated solutions to tasks that would other wise take us longer to accomplish manually.
