A new research is being carried out to develop DDS that automatically administer drugs instead of repeated injections for the patients who requires regular injections of drugs, as in the case of diabetes. However, its size and shape structure have been constrained due to limitations in the power supply needed to operate such a device. The research team found the answer lies in solar energy. Up-conversion nanoparticles were used for the photovoltaic device to induce the generation of photovoltaic energy with NIR light that can penetrate the skin. A drug delivery system consisting of a mechanical and electronic system that generates electrical current by irradiation with NIR light. When electricity is applied in this way, the thin gold film sealing the drug reservoir melts and the drug is released. This time saving technique is a future of healthcare. Since, many patients get injected on a regular basis, they endure pain each time. This can affect the skin of those individuals which creates chances of giving rise to another disease when we are already in the middle of treating the existing disease. But in some case this situation is vice-versa.
Also, some people have the phobia of needles and they don’t want that needle to be inserted into their body. Observing this problem, researchers have invented a unique and a smart way to deliver drugs into body. It was discovered by Pohang University of science and technology. The teams of researchers have developed near infrared light triggered drug delivery system. This new concept will make everything handy and even reduce people’s suffering. This system includes a new technique which has a different functionality and drug is released from in vivo medical devices simply by shining light on the skin. The shining light will inject the medicine properly according to consumer need. A team of research led by professor, Sei Kwang Hahn , belongs to the department of material science and engineering and professor Kilwon Cho Who belongs from the department of chemical engineering at POSTECH have together developed an on demand drug delivery system with the help of an organic photovoltaic cell coated with up-conversion nanoparticles. This brand new system which is called as DDS allows nanoparticles to convert a potential penetrating.
