Patent CA-2889518-A1 (CA)
Title: An amphiphilic block copolymer, the preparation method thereof, and a micellar drug-loaded system formed by said copolymer and an anti-tumor drug
Inventor: LIU KE
IPC: C08G63/91
Filed: 2013-09-22
Abstract: The present invention relates to an new type amphiphilic block copolymer and preparation method thereof, and a micellar drug-loading system formed by the copolymer with an antitumor drug. The amphiphilic block copolymer comprises an amphiphilic chain segment and a hydrophobic chain segment, wherein the end-group of the hydrophobic chain segment is blocked with a hydrophobic group. The amphiphilic block copolymer of the present invention employs a polyethylene glycol monoethylether (or polyethylene glycol)-polyester block copolymer with a recognized safety as a base material and the end-hydroxy of the polyester chain segment is modified with a hydrophobic group, which not only improves the compatibility of the drug molecule with the hydrophobic chain segment of the block copolymer and increases the force therebetween, but also provides a bigger space for accommodating the drug molecule; the prepared micelle can more effectively confine the drug molecule in the core of the micelle so that the drug molecule does not dissolve easily, thus the drug-loading micelle with high stability is obtained.

Filed: 2016-01-15
Abstract: A dissipation-based sensor includes a single resonator with a nano-structured surface. The sensor exhibits improved sensitivity, up to about 2 orders of magnitude higher than a single resonator without a nano-structured surface. The sensor operates by measuring and estimating the fluid friction per oscillation cycle, operating in normal conditions without vacuum (e.g., in air or other ambient gas) at room temperature. The sensor can provide measurement data at a speed that is orders of magnitude faster than pre-existing resonance-based methods, as it is based on measurements from a few cycles only. The dissipation-based sensor may be utilized in a broad range of fast, inexpensive, hand-held measuring devices.  Additionally, the sensor is capable of operating at standard temperature and pressure.

Abstract: A fluid metering system for accurately and consistently mixing two or more fluids together. The fluid metering system generally includes a closed loop feedback system that monitors the flow rate of the water and the volume of liquid chemical added to the water over a period of time.
