    摘要: A nano-particle containing apparatus, a nano-particle detection system and a method are disclosed. The nano-particle containing apparatus includes a casing, an air extracting device, a pressure device and a measuring instrument. The casing has a containing space for disposing a plurality of nano-particles. An internal wall surface of the casing has active self-cleaning function. The pressure control device controls the pressure status of the containing space. The active self-clean function is that nano-particles adhered to the internal surface wall are removed into the containing space. The nano-particles then are pumped by the air extracting device from the containing space. The measuring instrument then detects the status of an object affected by the nano-particles after the object is delivered into the containing space.

    摘要: A blood flow control system, tension adjustable instrument and a method are disclosed. The blood. flow control system comprises a detecting unit, a computing and a tension adjustable instrument. The detecting unit real-time monitors the biomolecular response condition of a living organ, and the computing unit dynamically controls the tension adjustable instrument to adjust the tension of the blood vessel based on the detecting result. Therefore the blood flow control system can maintain the biomolecular response condition over a predetermined range to reduce the risk of the liver organ being damaged and augment the curability.

    摘要: A charged mesoporous silica nanoparticle (MSN)-based drug delivery system for controlled release and enhanced bioavailability is disclosed. The system comprises a positively charged MSN, which has a silica matrix and an array of pores and/or nanochannels in the matrix. The entire substance of the matrix, all the surfaces and the pores and/or nanochannels comprise a plurality of silanol (Si—OH) and quaternary ammonium functional groups. The bioavailability of a negatively charged bioactive compound can be increased by loading it into the pores and/or nanochannels. The silanol (Si—OH) functional groups on the surfaces lining the walls of the pores and/or nanochannels are free to deprotonate in a fluid having pH above the pI of the positively charged MSN and lead to a sustained release of the negatively charged drug from the pores and/or nanochannels, and thereby enhance the bioavailability of the drug.
