Introduction Biosensor based on micro-machined resonator is a new bio-chemical analysis method, which relates to the MEMS, Materials, Bio-chemistry, Mechanical and other cross-disciplinary subjects.
However, the Q-factor is rapidly decayed in liquid due to the large damping, which makes some resonant structure not suitable to work in liquid.
This paper presents a paddle structure working in the torsional mode, by which the resonator can achieve higher Q-factor.

In biomimetic process, the biological systems store and process information at the molecular level, and the chemical co-precipitation process [3,4] creates the organized nanocomposite structure.
Because polyamide is similar to collagen protein in chemical structure and active group, it is biocompatible and tough. [6] Accordingly, polyamide 66 (PA66) was selected to prepare n-HA/pa66 composite.In 1991, Kokubo et al. [7] proposed that the essential requirement for an artificial implant to bond to living bone was the formation of bonelike apatite on it’s surface.
The change of a2-crystal at 2θ=23.88° means a highly possible change of the PA66 crystal structure in the compositeIt is known that the crystallinity of PA depends on its hydrogen bonds.

Self-conversion of hydroxyphenols to quinones is responsible for the generation of gold nanoparticles with different surface structures. 2.2 Template method and nano architectonics Ordered arrays of gold nanoparticles play an important role in nanoelectronic and nanophotonic applications.
Moreover, another metal can be added to the AuNPs, leading to a core-shell structure with controllable dimensions.
The MIS structure has an excellent memory effect and high retention time up to 20000 s.
For example, how combine the gold nanoparticels with the green chemistry and how to apply gold nanoparticles to biomedical.

When the surfactant concentration above the critical micelle concentration (CMC) in the VES fluid, the micellar structures entangles and forms a three-dimensional grid structure.
Because of these structures, clean fracturing fluid can still carry proppant at low viscosities [1-4].
