    摘要: Biological reactions are carried out with a unitary structure, preferably formed of a ceramic material, having a plurality of flow passages including first and second sets of flow passages arranged so that individual passages of the first set are adjacent individual passages of the second set and are separated by walls formed of the ceramic material. The ceramic material is porous to provide mass transfer of gaseous oxygen and biological reaction products while containing liquid in the second set of passages. Walls of the passages may be covered with a gaseous oxygen permeable membrane. Inside walls of the second set of passages may coated with a compound adapted to immobilize biological reaction materials. In a biological reaction, the first set of passages are contacted with a fluid such as an air stream to provide gaseous oxygen, and a fluid flow such as a nutrient medium is established through the second set of flow passages whereby an oxygen flow producing gradient is produced through the porous ceramic material between the first and second sets of flow passages to supply oxygen for cells immobilized on inside walls of the second set of flow passages.

    摘要: A process for the preparation of functional molecules using the thiol-ene coupling reaction and a process for the preparation of protected functional thiols, specifically thioesters is provided. The methods may be used to make functional polymers and other molecules. The method of making a functionalized polymer using a thiol-ene reaction comprises: providing a functionalized thioester having the following formula: wherein R is a functional group and COR′ is a protecting group; cleaving the functionalized thioester, forming a functional thiol and an acyl group; providing a polymer having a pendant vinyl group; and reacting the polymer with the functional thiol whereby a functionalized polymer is formed, wherein the functional thiol is not isolated prior to reacting with the polymer.

    摘要: A polarization-modulation scanning laser microscope includes a conventional laser scanning microscope, which has been improved by addition of: a polarization state generator; a polarization state analyzer; a photo-detector for receiving laser light transmitted though a sample; a signal demodulator providing two signals in response to the transmitted laser light, one of the signals being indicative of polarization orientation, and the other signal being indicative of magnitude of the transmitted polarized light. A relay interface toggles between the two signals provided by the signal demodulator and at least one other signal provided either by the photodiode of the laser scanning microscope, or by an external optical beam induced current, or both. A signal processing unit provides an image output to a display device.
