Four Chemical Engineering UB students find innovations on how to accelerate wound healing. under the guidance of Supriyono, S.T., M.T., the team consist of Lyla Lilia Fitria Hikma, Chindy Wulandari, Aulia Azzahra, and Nasirotul Wildah.
“Usually the first treatment in wound healing is an ointment, we want to introduce another alternative to accelerate wound healing on the skin, the scaffold tissue,” explained Lyla as team leader.
The basic material of this scaffold tissue is usually made of synthetic hydroxyapatite (HA). But it has very low mechanical properties compared to natural hydroxyapatite (HA).
The team is currently working to improve the low mechanical properties by coating metals, composites with polymers, and composites with ceramics.
The hydroxyapatite (HA) used is biocompatible and non-toxic to the body. According to the literature, 50% of bone is formed by modification of HA which acts as the main bone mineral. On the other hand, the porous HA Implant usually acts as a local drug delivery agent to the bone.
“We will utilize nano-sized HA to increase the mineralization ability of cells in vivo so that it can be absorbed by the enamel layer more strongly,” said another team member, Cindy.
This nano-sized HA, she continued, has the potential to revolutionize hard tissue implant techniques, namely bone and tooth repair, as well as for drug delivery systems.
The synthesis of hydroxyapatite particles was carried out electrochemically because it was simple, the process was easy, inexpensive, environmentally friendly, and could control the particle size by adjusting the current and voltage used.
With this innovation, the team will fight to be able to represent UB in the upcoming 2021 National Student Scientific Week (PIMNAS). (humasft)
