Printing with Light and Turning Plastic into Life-Saving Materials

 

By Dr. Monsur Islam

What if we could transform a simple plastic sheet into a high-tech material for biomedical use, just by using a laser? Our research makes this a reality with laser-induced graphene (LIG), a lightweight, flexible, and highly adaptable material that can be created in a single step merely through engraving on a plastic with a laser beam. Unlike complex and expensive fabrication methods, it is a fast and cost-effective process and allows for customized designs suited for several medical applications.

LIG’s unique properties make it a promising material for tissue engineering and bioelectronic devices. Because it is easy to shape and integrate with other materials, it could be used to develop biodevices, smart implants, and scaffolds for tissue repair. For example, it may one-day help muscles regenerate more efficiently or improve medical sensors that interact seamlessly with the body.

The image above shows a muscle cell (highlighted in red) anchored to the porous surface of LIG, demonstrating the biocompatibility and cell affinity of the LIG material. For reference, an image of the LIG material is given at the left corner, highlighting the flexible nature of LIG. With its simple fabrication, flexibility, and broad potential, LIG opens new possibilities for healthcare and medical innovation. This research brings us one step closer to making advanced, customizable materials for healing and beyond.
