A method of preparing low water-soluble medicine into solid nanometer pharmaceutical formulation is disclosed. According to the characters of molecular aggregates such as supramolecular chemical micelles and vesicles, the formulation, which based on the hydroxypropyl-beta-cyclodextrin and phospholipid, is prepared under the condition of hyperthermia sterilization and decompression. Such nanometer formulation is sterile particle or powder with loose porosity. For directly intravenous use, the formulation has targeting activity, sustained release and long circulating characters. While as a solid oral product, it is fast-release, fast-effective, and improved bioavailability characters, and is readily melted in mouth. The formulation utilizes secure accessories, traditional equipments and methods, thus, it is suited to be used and manufactured widely. Also disclosed is intravenous formulation of anticancer paclitaxel, which characterized that there has no polyoxyethylenated castor oil in it. Such intravenous formulation is nonallergic so that it has higher security and efficiency compared to present commercially available paclitaxel formulations.

The design and deposition of a sensing layer for room temperature SAW / BAW chemical sensors utilizing macrocyclic compounds in accordance with supra-molecular chemistry principles. The gas to be sensed is attached to the organic sensing film thus changing its visco-elastic properties and creating a mass increase of the film deposited on the surface of SAW / BAW devices. A direct printing method can be used as an additive, mask-less procedure to deposit metallic interdigital transducers and electrodes required for SAW / BAW devices, along with the deposition of a guiding layer and the organic filmsonly on the location required by the sensing SAW / BAW principle of the sensor. Different thermal treatment solutions can be used for the consolidation of the gelly organic films deposited by the direct printing methods.
