Surface acoustic wave (SAW) biosensors possess advantages of high efficiency, low cost and label free detection, and have potential applications in clinical diagnostics. However, it is a great challenge for SAW biosensors to detect small concentrations of biomarkers in clinical sample. Nanomaterials have been widely used in bioanalysis techniques to fabricate highly sensitive biosensors. In this paper,...
To realize the potential of SAW devices in portable sensing applications, it is important to reduce the power consumption and improve sensitivity of existing surface acoustic wave (SAW) sensors. In this work, we designed several SAW sensors based on ST 90o-X quartz and silicon dioxide (SiO2) waveguide with or without filled microcavities to achieve both these in a single device. A 3D finite element...

Summary and Perspectives
DNA origami, in which a long single strand of DNA is folded into a shape using shorter ‘staple Strands’, promises low-cost ways to create nanoscale shapes and can even display patterns of binding sites of 6-nm-resolution, in principle allowing complex arrangements of carbon nanotubes, silicon nanowires, or quantum dots [1]. However, adsorption of origami appears better results on mica substrate, which...
Using self-assembled DNA tetrahedron, we were able to precisely control the gain in optofluidic FRET lasers. 3.8 times reduction in the lasing threshold and 28-fold enhancement in the lasing efficiency were demonstrated.
This paper reports a rapid and visual detection of mercury ion on a new developed digital microfluidic chip with electrostatic manipulated droplets, which employed a principle of conjugated polymers and label-free oligonucleotides for mercury ion detection. The complex of water-soluble conjugated polymer, poly (3-(3'-N, N, N-triethylamino-1'-pro-pyloxy)-4-methyl-2, 5-thiophene hydrochloride) (PMNT)...
