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.

The invention belongs to the technical field of super molecular chemistry, and particularly relates to L-glutamine organogel containing 1-cyanotoluylene and a preparation method thereof. The organogel is a mixed system consisting of an organogel agent and a solvent. In the system, the organogel agent is L-glutamine organogel containing 1-cyanotoluylene, and the concentration of gel is 1-5 milligrams / milliliter. The organogel is obtained by dissolving a small molecular organogel agent in an organic solvent or a mixture of an organic solvent and water under a heating condition and cooling to room temperature. The organogel can be used for gelating 12 types of solvents such as toluene, chlorobenzol, dichlorobenzene, methylene dichloride, methanol, a mixture of DMSO (Dimethylsulfoxide) or DMF (Dimethyl Formamide) and water, and the like, and the system represents an aggregation induction fluorescence enhancement phenomenon in the gelating process. Due to the aggregation induction fluorescence enhancement property, the application of the L-glutamine organogel to a temperature-sensitive fluorescent switch becomes possible.

The invention discloses a high saline alkali reactive brilliant blue KN-RSR dye composition and a preparation method thereof, which belong to the technical field of reactive dyes, and solve the problem that reactive brilliant blue molecules are easily associated and hydrolyzed to separate out in the prior art. The high saline alkali reactive brilliant blue KN-RSR dye composition is a homogeneous mixture based on a complex synergism principle, and utilizes a supramolecular chemistry theory, so that the defect that the saline-alkaline resistance of reactive brilliant blue KN-RSR is poor under the condition of conventional dyeing is improved, meanwhile, the enhancement performance of dye is increased, and the dye composition has excellent leveling property and pile-onproperties; the high saline alkali reactive brilliant blue KN-RSR dye composition not only can be used for dyeing cheese and finished garment which have higher requirements on leveling property, but also can be applied in currently favored energy-saving and environment-protecting dyeing: cold padder dyeing.
