Researchers of MIT and Harvard institutions have made the use of living microbes to introduce 3D-printed masks by using resins and chemicals. With the help of chemicals and two different types of resins, a particular layer of microbes fluoresce to create patterns and design in certain colors. Known as hybrid living materials (HLMs), scientists have made use of two different resins in making 3D-printed masks.
The solid material is used to make the bulk of the object in order to provide structure to this mask and another type of resin is used to make temporary supporting sections. Due to the absorbent properties of secondary resin material, certain chemicals have been used to fill it after printing. Microbes start to glow in different colors near the areas made with absorbent resin.
Researchers have chosen the chemicals to place in certain sections of the 3D object after taking into consideration the ability of those chemicals to activate certain genetic responses in the bacteria to make them fluoresce. With the help of the swapping of different resins structures and microbes, the objects have been programmed to make them glow in different patterns and colors. Most of such jobs are carried out using 3D Printing in Dubai. In today’s time, Dubai has become a popular hub for 3D printed objects.
Rachel Soo Hoo Smith, the co-lead author of this research work has said that they are capable of defining very specific shapes and distributions of the hybrid living materials and the biosynthesized products within the printed shapes. According to the team of researchers, this technique can be used in the future to prepare biomedical devices as well as smart packaging in order to detect bacterial contamination.
