LED light illuminates coral growth and facilitates bone transplantation in the future

According to comprehensive media reports, in addition to viewing, corals with bright colors have also been used for medical purposes such as bone transplantation. However, due to the slow growth of corals and the scarcity of serious piracy problems, it is difficult to obtain materials. Ding Chuxi, an associate professor at the Institute of Opto-Electrical and Integral Engineering at Chung Chung University, studied the rapid propagation of corals and used different LED lighting to make hard corals grow more than 10 times faster.

Ding Chuxi found that the nutrients that promote coral growth mainly come from symbiotic algae in the body, while symbiotic algae need different light at different stages of growth. For example, photosynthesis requires yellow light and green light, but it must rely on blue light to stimulate. Therefore, he uses artificial cultivation methods to continuously illuminate LED or OLED lights 24 hours a day, and adjust the wavelength and brightness of the light to successfully accelerate the growth of hard corals by more than 10 times. At the same time, the artificial breeding method can also exclude the wild collection may contain The risk of bacteria.

In addition, corals have high requirements for water quality. Dingchu has created a marine-like environment for this purpose, and continuously detects the concentration of trace elements such as calcium, magnesium and barium, and adjusts the color temperature controller of LED lamps.

It is estimated that the global market for hard coral coral materials will reach 3.4 billion US dollars in 2017. Dingchu has not only applied for various patents for this coral breeding technology, but also signed a three-year industry-university cooperation with Taiwan Biotechnology Company and transferred technology. The future is expected to make bone transplantation and implants more convenient.
