Copper (II) zinc (II) cobalt (III) complexes with the Schiff base derived from salicylaldehyde andd-glucosamine were synthesized. These compounds abbreviated as SG, CuSG, ZnSG, CoSG were characterized by elemental analyses, IR, UV-Vis,1H NMR and MS spectrum. ESR spectrum, magnetic susceptibility measured by Evans method for CuSG had also been done. It is suggested that the complexes in solution have pseudotetrahedral structure. It was found that SG would occur a photochemical reaction if a beach of 355 nm ultravisible light shone on its aqueous solution. The reaction was in further research.

The detection of human fibrin has been performed by immunological piezoelectric quartz crystal microbalance technique. Anti-fibrin antibody was immobilized onto the gold electrodes of a 9 MHz AT-cut piezoelectric quartz crystal with bovine serum albumin adsorption, followed by glutaraldehyde cross-linking. The antibody-bound crystals had good response to human fibrin in the concentration range of 10−4∼10−1g/L. The sensor system had good selectivity. The crystal could be regenerated nearly 10 times without detectable decrease of sensitivity.

A new method of determination of trace CN− in water was proposed. A thin film of Ag2S was electrochemically deposited on both sides of a silver coated piezoelectric crystal. The Ag2S−Ag films can react with CN− selectively, which causes the frequency shifts of the plezoelectric crystal. The frequency shifts are proportional to the concentration of CN− in the range of 10−6≈10−3 g/L. XPS experiments indicated the sensing film was Ag2S−Ag. A coordination complex Ag−CN− was formed when Ag2S−Ag film contacted with solution containing CN− ion. A response mechanism was proposed based on the XPS data.

The theory of Meridians is an important part of Traditional Chinese Medicine. Modern science should play its role in analysing and making clear the mystique of the theory. The relation between the activities of liquid crystals in acupuncture points and the regulative actions of Meridians was studied in this paper. The results showed the intimate intrinsic association between them.
