Abstract
The present disclosure provides functionalized powder particles and methods of forming functionalized powder particles. The functionalization is acquired through the formation of primary and/or secondary structures on a powder particle. Functionalization can be controlled to bring about changes in a broad range of physical and/or chemical properties.
Claims19
A method of lysing a cell, the method comprising:
- (a) providing a vessel containing one or more surface etched powder particle(s) within a chamber of the vessel, wherein each of the surface etched powder particle(s) independently comprises a crystalline, polycrystalline, semi-crystalline, or amorphous semiconductor or insulator powder particle, wherein each of the surface etched powder particle(s) has a diameter between 1 and 1,000 microns, and wherein a surface of a powder particle is etched such that each of the surface etched powder particle(s) independently comprises a structure selected from the group consisting of pores, pits, craters, nanowires, cones, pinnacles, hoodoos, coral, cords, walls, fins, ridges, crags, pyramids, and inverted pyramids;
- and
- (b) flowing a composition comprising the cell through the chamber of the vessel, wherein the one or more surface etched powder particle(s) contacts the cell, thereby lysing the cell.
