METHOD FOR FORMING APATITE FILM BY USING LASER

Title:

METHOD FOR FORMING APATITE FILM BY USING LASER

Document Type and Number:

WIPO Patent Application WO/2020/050579

Kind Code:

A1

Abstract:

Provided is a method for forming an apatite film, comprising the steps of: making a precursor solution containing Ca2+ ions and PO4 3- ions come into direct contact with at least some of a region of a substrate; emitting lasers at the region on the substrate, which comes into direct contact with the precursor solution, by allowing the laser to pass through the precursor solution; and forming apatite on the region at which lasers have emitted.
