摘要： The present disclosure is directed to an in-liquid laser-based method for fabricating a solution of fine particles of amorphous solid medicinal compounds, a solution of fine particles of amorphous medicinal agents made with the method, and fine particles made with the method. By using a target solidified via a phase transition process to covert an initial crystalline structure into an amorphous solid, technical difficulties with handling a hydraulically-pressed target are overcome. The laser-based ablation process produces amorphous solid medicinal compound fine particles, which improves the bioavailability and solubility of the medicinal compound. The improvement results from a combination of: disordered crystalline structure and enlarged relative surface area by particle size reduction. The laser based method may be carried out with ultrashort pulsed laser systems, or with UV nanosecond lasers. Results obtained with an ultrashort near IR laser and a UV nanosecond laser show formation of amorphous solid curcumin fine particles.

摘要： A method of forming nanometer sized fine particles of functional ceramic from a bulk functional ceramic, particularly fine particles of phosphorous ceramics from a bulk phosphor material is disclosed. The method relies on irradiation of a bulk phosphorous ceramic in a liquid with an ultrashort-pulsed-laser-fragmentation beam to thereby form nanometer sized particles of the phosphorous ceramic. The method is unique in that the generated particles retain the chemical and crystalline properties of the bulk phosphorous ceramic. The generated solutions are stable colloids from which the particles can be isolated or used as is.

摘要： In the present invention, a method of producing stable bare colloidal gold nanoparticles is disclosed. The nanoparticles can subsequently be subjected to partial or full surface modification. The method comprises preparation of colloidal gold nanoparticles in a liquid by employing a top-down nanofabrication method using bulk gold as a source material. The surface modification of these nanoparticles is carried out by adding one or multiple types of ligands each containing functional groups which exhibit affinity for gold nanoparticle surfaces to produce the conjugates. Because of the high efficiency and excellent stability of the nanoparticles produced by this method, the fabricated gold nanoparticle conjugates can have surface coverage with functional ligands which can be tuned to be any percent value between 0 and 100%.
