成果简介	NOVELTY - Light-driven dual-dye tagged micromotor (100), comprises a base layer (101); a first layer (102) assembled over the base layer; and a second layer assembled over the first layer. The base layer is a uniform layer of silica microparticles over the silicon substrate. The first layer is a photocatalytic layer that enables driving of the micromotor in an aqueous peroxide fluid medium under UV light. The second layer is a layer of multiple dye molecules, in which a primary dye coating (103) is applied over a first half of the first layer at a polar angle, allowing for selective tagging and tracking of the micromotor and a secondary dye coating (104) is applied over a second half of the first layer after rotating the base layer in an azimuthal plane for enabling a dual dye tagging and facilitating in multi-directional tracking. The substrate is a silicon substrate and the micro particles are silica micro particles. The photocatalytic layer is a layer of titanium dioxide. USE - Light-driven dual-dye tagged micromotor for use in biomedical applications. ADVANTAGE - The properties of materials and light sources are so chosen to use the micromotor for easy tracking and real-time monitoring within optically complex environments. The micromotor has a simplistic structure, single-step structure, cost-effective model, and site-specific materials coating obtained from the physical vapor deposition (PVD) technique for efficient tracking in fluid medium during biomedical applications. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for synthesizing a light-driven dual-dye tagged micromotor, which involves: a) uniformly distributing silica microparticles on a substrate to obtain a silica microparticle coated base layer; b) subjecting the silica microparticle coated base layer into a high vacuum chamber followed by depositing the silica microparticle coated base layer with a first layer to obtain a first layer coated structure; and c) coating each of the second layer over a predefined portions of the first layer coated structure by rotating the silica microparticle coated base layer to obtain a light-driven dual-dye tagged micromotor. DESCRIPTION OF DRAWING(S) - The drawing shows an exploded view of the light driven dual-dye tagged micromotor. 100Light-driven dual-dye tagged micromotor 101Base layer 102First layer 103Primary dye coating 104Secondary dye coating
