A sol–gel technique was applied for the preparation of water-compatible molecularly imprinted polymer (MIP) for solid phase microextraction (SPME) using diazinon as template and polyethylene glycol as functional monomer. The MIP-coated fiber demonstrated much better selectivity to diazinon and its structural analogs in aqueous cucumber sample than in distilled water, indicating its potential in real...
This paper presents a simple and cost-effective UV-ablation technique for fabrication of size-tunable nanofluidics devices via photochemical decomposition reaction. UV-irradiation through a PET photomask results in continuous decomposition of poly(carbonate) (PC), forming nanochannel and carboxyl groups on the surface of the etched PC. This photochemical decomposition process occurs at molecular scale,...
Massively parallel genomic DNA fragments display on chip plays a key role in the new generation DNA sequencing. Here, we developed a new technology to display the parallel genomic DNA fragment massively based on two-step reaction with Ф29 DNA polymerase. The genomic DNA fragments were firstly amplified by rolling-circle amplification (RCA) reaction in liquid phase, and then amplified further on the...
Inherent problems exist with sequencing-by-synthesis (SBS) methods which use fluorescein-labeled nucleotide incorporation into a target template based on a polymerase chain reaction (PCR). These problems include lowering the cost of sequencing and the removal of fluorescence in DNA sequencing for further reading. How can these sequencing problems be resolved? We present a sequencing strategy which...
