Two Hong Kong students invented the self-sterilizing door handle, the team afraid of dirty like this

That is really a correct judgment, because when you look back, you will see that most of the inventions we use every day are quite basic. All you need is a good idea and some relevant knowledge. That's exactly what happens with two teenage boys from Hong Kong, China that we will talk about below.

Sum Ming, 17, and Kin Pong, 18, who were studying titanium dioxide properties realized that it could be applied to a very familiar item, such as a door handle, and It can really change the lives of many people.

This is no ordinary door handle, because it can kill bacteria, but only need light!

Antiseptic door handle.

Sum Ming Wong and Kin Pong Li found that titanium dioxide was extremely effective at killing bacteria and came up with the idea of ​​grinding this substance into fine powder. The boys also noticed this substance would work more effectively when exposed to UV light. And the duo have devised a simple but genius product that can make the most of their innovation.

This door handle was created by two Hong Kong university students

Two teenage students invented the bactericidal door handle.

The door handle is one of the most bacteria-containing places in the entire human civilization. Knowing that, the duo designed a handle made of a glass tube with two ends sealed with two small pieces of aluminum. The whole glass tube section is covered with titanium dioxide powder mentioned above.

The handle is also coated with an optical catalyst, meaning that when light is present, a chemical reaction will be performed.

Disinfectant door handle design with durability and high efficiency.

" We know that many infectious diseases can be spread by contact, such as SARS, MERS, hand, foot and mouth disease, and Candida fungus," the two students said. " Today people use chemical cleaners to clean public areas, but those substances are also easily wiped away and harm the human body. Our designs are durable. and efficiency ".

Chemical reaction triggered by UV light will decompose bacteria on the door handle.

The inspiration to find a similar solution came after the SARS pandemic in 2003.

The two students also said their inspiration to find a similar solution appeared after the SARS pandemic in 2003, affecting more than 8000 people worldwide, and China alone had 700 deaths.

This invention has been shortlisted for the James Dyson Awards 2019 and is one of the winning products.
