In the chemistry department of Peking University in china, Jiang Ziwei[4] used the calcium selective electrode to analyzes the human bile directly in order to study the role of calcium in the formation of gallstones.
For different CPU system structure, this part does not have portability.
It can be used in detection domains of medicine, biology, chemistry etc. and has broad application prospects.

DMA was synthesized by the methods in the literature. [10-12] The structures of it were confirmed by 13C NMR techniques.

Introduction The micro-arc oxidation (MAO) is a novel technology, including the micro plasma electric discharge, the complex electrochemistry, plasma chemistry and the thermochemistry process, by which oxide compound ceramic films are grown on the surface of valve metal alloys, which has been developed rapidly in recent years [1-3].
In this paper the nanostructured surface layer was produced on the Ti-6Al-4V alloy by SMAT technique, and then the compound ceramic coatings of surface SNC/MAO were prepared on the nanocrystallized surface of Ti-6Al-4V alloy by MAO, and the phase composition and structure, morphology and the anti-falls off curving tests were discussed.

Because of their distinct structures and properties, EMFs show a great deal of potential applications in many fields such as materials science, photovoltaics, nanoelectronics and biomedicine.[1,2] Though some EMFs are available in laboratory, the extremely low yield delays their investigation and application in many fields.

Conclusion Detailed surface studies have shown that the combination of an apatite abrasive and a HA dopant in the continuous process produces surfaces with a combination of optimized apatite chemistry and controlled surface structure.
The continuous process has the ability to retain the chemistry of the starting HA material.

In the past few decades this technology has established itself in the ground of material science and its use is now being extended to sensor technology, biomaterials and nano particle formation [5-6] Because the non-melted sol–gels usually have a porous structure, many compounds can be entrapped into the sol–gel matrix.

Assuming porosity is similar for all ceramics, the impacting factors of surface topography and the underlying material chemistry will be carefully evaluated.
Figure 2(b) illustrated the uniform structure of the nHA and the range of grain size was approximately 70~90 nm.
The surface chemistry of BGC and HA/TCP did not play an important role on the initial adhesion rate of osteoblast.

Biosensors containing enzyme is analytical devices that incorporate enzyme components and transducers, have been widely applied in chemistry and biology due to their high sensitivity and potential selectivity[3].
