Abstract: A pharmaceutical composition containing a mixed polymeric micelle and a drug enclosed in the micelle, in which the mixed polymeric micelle, 1 to 1000 nm in size, includes an amphiphilic block copolymer and a lipopolymer. Also disclosed are preparation of the pharmaceutical composition and use thereof for treating cancer.

Abstract: The present invention discloses a LPR sensing device and a LPR sensing system comprising a LPR sensing device, a light source, a detecting unit and a processing unit. The LPR sensing device comprises a sensing substrate and a noble metal nanoparticle layer, and the noble metal nanoparticle layer is disposed on the sensing substrate and has noble metal nanoparticles with diameter of 2˜12 nm. An analyte adsorbed on the surface of the noble metal nanoparticle layer generates a dielectric environmental change, resulting in a change of the LPR band. Comparing noble metal nanoparticles with different particle diameters, small noble metal nanoparticles provide better sensing sensitivity to a compound with a small molecular weight.

Abstract: An adjustable forearm crutch, wherein the fork support is formed with a central reinforcing rib for increasing the bending-resistant strength of the fork support, the reinforcing rib and the adjacent wall of the fork support defining a recess. After the fork support is molded, the recess can serve as a standard face for the processing procedure so that when punching holes on the fork support, no deflection will take place. The fork support and fixing tube being inserted in through holes of a sleeve member so that the waste chips and water produced when processing the fork support can be easily removed. The through hole of the sleeve member for receiving the fixing tube is formed with an annular groove which provides a resilient clamping effect, the end of which is cut into several equal sections for providing resilient clamping effect, so that the adjusting tube is firmly supported at two points without loosening or swinging.
