Development of bioimplants with both
biocompatibility and antibacterial properties

Bioimplants used in vivo should have a high affinity with living tissues and cells. At the same time, resistance to bacteria is also required if we take into account long-term use.
In order to solve this problem, our laboratory is attempting to create a surface that is “friendly to cells and strong against bacteria” using various surface creation processes. Laser processing, for example, is one such method. Irradiating a material with laser changes the geometrical shape and chemical composition of its surface, which in turn alters its interaction with living cells, tissues, and bacteria. Focusing on this phenomenon, it is believed that it may be possible to create a surface that “cells adhere to instantly, but one which bacteria do not approach at all”. The aim is for new breakthroughs in the medical and biotechnology fields by utilizing such methods.
