Identification And Characterization

Identification and characterization of CTCs can be used as a tool for the study of cancer metastases. A novel design of microfluidic chip used for enrichment of circulating tumor cells is presented in this paper. An integration of DLD method and negative enrichment method were designed to improve the throughput and recovery rate while getting intact CTCs. The DLD stage is used to separate CTCs from blood cells preliminarily, and the negative enrichment stage is used to acquire purified CTCs. Both of them were simulated with COMSOL Multiphysics. Simulation results showed that triangular micro-posts have better performance in DLD stage, and wave structures could generate better disturbance effect than herringbone structures. This chip provides a potential approach with high throughput and purity for the enrichment of CTCs.

Novel Approach

AbstractThis manuscript describes a novel approach for the preparation of composites based on cellulose paper (CP) modified with polypyrrole (PPy) and bromophenol blue (BPB) (CP/PPy/BPB). Cellulose fibers are suitable for uniformly retaining the polymer in its doped form, once BPB can be used as a negatively charged dye. The CP/PPy/BPB composites were characterized by Raman Spectroscopy, Scanning Electron Microscopy, Spectroscopy and Dispersive Energy, and X-ray Diffraction. After characterization, they were studied for the quantification of pH and ammonia by diffuse reflectance spectroscopy. Under varying pH, different colors were verified, which ranged from yellow to blue, and an optical response for ammonia at concentrations as high as 25 ppm. The replacement of BPB by bromothymol blue (BTB) did not produce efficient color transitions and showed no sensitivity to changes in pH and ammonia concentration.

In this paper, microfluidic chips supply a miniature platform for aptamer biosensor in thrombin detection. The aptamer biosensor was integrated to the microfluidic chip as a recognition element for thrombin detection. Experimental results showed that the aptamer biosensor in microfluidic chip was able to realize the function for human thrombin detection.
