- He developed a technology that analyzes color changes with a mobile phone camera and allows hazardous chemicals to be easily detected.
- This technology; It has purposes such as detecting environmental pollution and preventing terrorism and security accidents.
- The sensor, which is less costly than traditional methods, was created using six different solvents that can distinguish between 14 volatile organic compounds and water.
DGIST Physics and Chemistry Professor Park Jin-hee and his research team have developed a technology that enables easy detection of hazardous chemicals. developed. The technology, which enables the detection of harmful substances by analyzing color changes using a mobile phone camera, is expected to be used for various purposes such as detecting environmental pollution and preventing gas leaks.
Volatile organic compounds are harmful chemicals commonly found in the environment. They enter the environment through factory gases, indoor air and other sources and cause pollution and sometimes even disease. Therefore, it is vital that they are detected quickly. Traditional detection methods can either be very costly or only detect a limited number of chemicals.
Dr. To solve this problem, Jin-hee Park and her team developed a sensor that uses a material called a “metal-organic framework” that triggers color changes. The sensor was created using six different solvents that can distinguish between 14 volatile organic compounds and water. The team developed large-area tapes that can be easily produced at low cost to enable color changes to be observed with the naked eye.
By analyzing color changes with a mobile phone, it becomes possible to qualitatively and quantitatively detect harmful compounds at low concentrations that are difficult to detect with the human nose. The sensors can be used for various purposes, such as detecting environmental pollution and preventing gas leakage, as they perform well even in high humidity environments.
Dr. “The sensors we developed have great commercial potential because they can operate without power and can be implemented at low costs,” Lee said. “With this work, we look forward to securing resource technologies to develop sensors for various purposes such as detection of environmental pollution, prevention of terrorism and security accidents.” He talked about the aims of the project with his statement.
