MUMBAI, India, Feb. 27 -- Intellectual Property India has published a patent application (202621004749 A) filed by Indian Institute Of Technology, Maharashtra, on Jan. 17, for 'a method for controlled sorting of colloidal particles in an evaporating droplet on a surface.'
Inventor(s) include Rajneesh Bhardwaj; and Bibek Kumar.
The application for the patent was published on Feb. 27, under issue no. 09/2026.
According to the abstract released by the Intellectual Property India: "The present disclosure provides a method and an apparatus for controlled sorting of colloidal particles in an evaporating droplet on a surface. The method comprises the steps of preparing a colloidal suspension in an aqueous medium, comprising particles of at least two distinct sizes, then depositing at least one droplet of the colloidal suspension onto a hydrophobic substrate surface, then exposing the droplet to an alcohol-saturated environment within an enclosed glass chamber, and finally allowing spontaneous spreading and internal recirculation within the droplet under the saturated alcohol condition thereby deposits differently sized particles into concentric rings, with smaller particles accumulating at the outer rim and larger particles segregating toward the interior of the concentric ring."
