| Abstract Scope |
In this research, we develop a nature-inspired droplet-based nanoparticle 3D printing method that creates highly complex three-dimensional architected structures and use them to make new device structures. Fluid dynamics of aerosol microdroplets is used to stack nanoparticles (or 2D nanoflakes) in 3D space without auxiliary support to create such structures. First, this technique is used to realize next generation biomedical devices such as a biosensor that detects COVID-19 antibodies and antigens in 10 seconds. This is the fastest detection time for this biomarker. Second, we use 3D printing to create fully customizable brain-computer interfaces (BCIs) having recording densities of thousands of electrodes/cm2, which is 5-10x higher than the current state-of-the-art BCI technologies. The technology is tested by recording the action potentials from the mouse brain. The same technique is also used to create high-capacity Li-ion batteries and thin flexible robotic skins with embedded sensors. |
