摘要： Composition comprising gas filled microcapsules and a bioactive agent, useful for an ultrasound-mediated delivery of said bioactive agent. The microcapsules comprise a relatively stiff shell of polymeric or lipid material and have in particular a resistance to a mechanical index of at least 0.15, while the bioactive agent is substantially unbound to the shell of the microcapsules. The composition of the invention is particularly suitable for effectively delivering a genetic material into a cell, upon exposure of the composition to a level of acoustic pressure capable of destroying a portion of the microcapsules and releasing the gas contained therein.

摘要： A sensor for use in the detection of a molecular interaction comprises a field effect transistor (FET) having a core structure and an extended gate structure, the core structure and the extended gate structure being located on substantially separate regions of a substrate, the extended gate structure including an exposed metal sensor electrode on which probe molecules can be immobilized, wherein, in use, the sensor is operative to produce a change in an electrical characteristic of the FET in response to molecular interaction at the exposed surface of the metal sensor electrode. The sensor is particularly suitable for detecting biomolecular interactions such as the hybridization of DNA, when the sensor is prepared with suitable probe molecules immobilized on the exposed gate metal.

摘要： The present invention relates to a photosensitive detector with a composite dielectric gate MOSFET structure and its signal readout method. The MOSFET structure detector is formed on a p-type semiconductor substrate. N-type semiconductor regions locate on the two sides of the top part of the p-type semiconductor substrate to form a source and a drain. An underlying dielectric layer, a photo-electron storage layer, a top dielectric layer, and a control gate are stacked on the substrate in sequence. The top insulating dielectric layer can prevent the photoelectrons stored in the photo-electron storage layer from leaking into the control gate. The source and the drain are floating when photoelectrons are collected and injected into the photoelectron storing layer to be held therein. There is a transparent or semi-transparent window for detecting incident light forming on the substrate or gate surface. This invented detector has excellent scalability, basic compatibility with the flash memory fabricating technology, low leakage current, higher imaging speed than CCD, non-sensitivity to processing defects, larger dynamic range than other structures and higher accuracy of signal readout.

摘要： The present invention relates to methods and compositions for culturing embryonic stem (ES) cells. The methods relate to growing the ES cells in the presence of small molecules of formula (I) that maintain the pluripotency/self-renewal of the cells without feeder cells and LIF in serum-free conditions. These methods in part facilitate much more consistency in embryonic stem cell production, providing, for example, new avenues in the practical applications of embryonic stem cells in regenerative medicine.
