A derivatization apparatus and method for coating a sample carrier with a reagent solution. The derivatization apparatus consists of a closed system in which a small quantity of reagent solution is sprayed into a closed container via a spray nozzle. A sample carrier is located in the closed container and is coated as homogeneously as possible with the reagent solution.

Methods for producing a cosmetic coating on a skin surface, by: (A) electrostatically spraying a composition comprising component (a) one or more volatile substances selected from the group consisting of water, an alcohol and a ketone, and component (b) a polymer having a film-forming ability directly onto the skin to form a coating on the skin surface; and (B) subsequently applying a powder-containing cosmetic on the formed coating, afford cosmetic coatings which can be removed without using a cleansing agent.

This invention discloses a method for controlling nanoscopic wetting near or at a molecular scale for synthetic material applications. In particular this invention relates to a method for preparing a monolayer or thin film with a patterned nanoscopic wetting surface using a ‘sitting’ phase of polymerizable amphiphile, wherein hydrophobic alkyl chains of the amphiphile extend along the supporting surface and the amphiphile molecules align side-to-side, effectively forming a repeating cross-section of bilayer with alternating hydrophilic and hydrophobic stripes of a ˜6 nm pitch tunable based on the chain length of the amphiphile. Products prepared according to the methods disclosed herein are within the scope of this invention. In some embodiments, monolayers or thin films so prepared are transferable.

A method of making a solution including poly(ethylene terephthalate). The method includes dissolving poly(ethylene terephthalate) in a solvent mixture to form a solution, the solvent mixture including two solvent components. A Hansen Solubility Parameter Distance between the solvent mixture and HSP coordinates having a dispersion HSP of 18.02 MPa.sup.0.5, a polar HSP of 5.56 MPa.sup.0.5, and a hydrogen bonding HSP of 14.27 MPa.sup.0.5 is less than about 2 MPa.sup.0.5.

The present disclosure relates generally to coating medical devices. In particular, the present disclosure provides materials and methods for coating a portion of a balloon catheter with a pharmaceutical agent using electrodeposition techniques. Although angioplasty and stenting can be effective methods for treating vascular occlusions, restenosis remains a pervasiveness problem. Therefore, coating portions of a balloon catheter with a pharmaceutical agent that inhibits restenosis can reduce the likelihood of restenosis.
