Welcome to “Paradise on Earth” — Suzhou! Built in 514 BC, Suzhou is an ancient city with 2500 years' history, located in the center of Yangtze Delta. It is renowned for the classic gardens, canals, silks, lakes, operas, legends and museums. In recently 20 years' fast-growing, Suzhou is changing her ancient face to a modern city and high-tech harbor, its GPD ranks Top 5 in the cities of mainland China...

This work mainly describes an electrochemical microsensor based on the reduction of molybdophosphate complex for fast determination of total phosphorus (TP) in water. Compared with the traditional methods for phosphate detection reported previously that used bulk electrodes, this microsensor responds faster, and can be applied to TP detection rather than merely phosphate. Calibration of phosphate...
This study reports a piezoelectric polyvinylidene fluoride (PVDF) polymer-based sensor patch for simultaneous heartbeat and respiration detections. The principle is based on the piezoelectric sensing mechanism to detect the pulsatile vibrations, and periodical deformations on the chest wall of human body during heartbeats and respirations, respectively. In this study, the sensor patch with a structurally...
A dynamic filling experiment using PBS with HepG2 tumor cells is performed for observing the attachment behavior in capillaries. A PDMS microchannel mimicking the capillary blood vessel is fabricated by the soft lithography. With treating the PDMS microchannels by different plasmas, the corresponding surface roughness (Ra) data are experimentally measured by AFM. Using these PDMS microchannels well...
Deoxyribonucleic acid (DNA) origami [1] is expected to be a nanoscale functional block for Nano Electro Mechanical Systems (NEMS). It can be assembled on a substrate containing other MEMS components to realize a NEMS device in which nanostructures play an important role. We recently demonstrated a tapping mode atomic force microscopy (AFM) process that can manipulate DNA origami structures in liquid...
The convergent microchannel is widely applied to connect microchannels with different sizes to avoid sharp changes of the flow field. It is important to investigate the dynamic properties in the convergent microchannel to promote the development of microdevices. Numerical simulation method is used to study the dynamic behaviors of microdroplets in a convergent microchannel. The microchannel is embedded...
Using ab initio many-body perturbation theory (within GW approximation and Bethe-Salpeter equation), including electronic exchange, correlation, and electron-hole interaction effects, we study the optical properties of large-diameter semiconducting single-walled carbon nanotubes (SWCNTs). The calculated energies of the lowest two optically allowed transitions (E11 and E22) agree well with those deduced...
In this paper, we focus on the development of membrane-typed metal mould with microstructures for imprinting. This mould has several benefits including reusable, easy replaceable core, and low cost that strongly improves industrial values in microstructure mass production. The membrane-typed metal mould with a thickness of 60 µm can be attached to a level mould or a roller mould, and becomes a metal...
This paper presents a novel ultraviolet (UV) irradiation assisted nanostructured ZnO film for high performance oxygen sensing under a low working temperature. The UV irradiation greatly increases the number of the excited electrons to attract the high electron negativity molecule of oxygen. The response for detecting the oxidation gases can be achieved without using the high catalytic temperature...
A micro electrochemical sensor has been developed for total nitrogen (TN) determination in freshwaters. After the digestion process of water samples, nitrate was detected with the microsensor modified by porous copper-clusters and the concentration of TN was calculated by a portable electrochemical system. As the electrocatalyst material, copper was electrodeposited onto the working-electrode of the...
Membrane proteins embedded in bi-layer lipids of cell membrane have unique functions including inter-cell communication, ions/molecules transport. And there is more than 50% of drug design emphasizes on membrane proteins specifically studying on their structure and formation. Recently we reported the structural and functional studies of membrane protein lipid nanoparticles in native biological membrane...
An evanescent wave fiber optic sensor for the detection of groundwater contaminants is developed. A 62.5 µm fiber core, 15 mm in length, was chemically etched and coated with 20 µm porous silica medium using sol-gel dip-coating method. This lower-refractive index medium causes the light beam to be transmitted by total reflection and the resulting evanescent wave produces a net flow of energy across...
