DNA-DNA Interaction on Dendron-Functionalized Sol-Gel Silica Films Followed with Surface Plasmon Fluorescence Spectroscopy

, , , , , ,
Since we observed that dendron-assembled surface providing a proper spacing between immobilized DNAs showed high single nucleotide polymorphism discrimination efficiency for DNA microarrays(1), the nanoscale-controlled surface is examined with surface plasmon field-enhanced fluorescence spectroscopy (or [...]

A Non-Oxidative Sensor Based on a Self-Doped Polyaniline/Carbon Nanotube Composite for Highly Sensitive and Selective Detection of the Neurotransmitter Dopamine

, , , , , , ,
The ability to measure the concentration of dopamine sensitively and selectively could potentially be used for molecular diagnosis of Parkinson’s disease. The ability to monitor its concentration in-vivo also benefits in design therapies and evaluating [...]

Development of SERS Spectroscopy for Routine and Rapid Identification of Escherichia Coli and Listeria Monocytogenes on Ag Colloidal Nanoparticles

, , , , ,
Rapid, accurate, and preferably routine methods for the identification of foodborne bacteria are increasingly important, because of bio- /agro-terrorism threats, public health concerns, and economic loss. Conventional detection of bacteria is time-consuming, requiring 5-7 days, [...]

Multiplexed immunoassays by flow cytometry for detection of Clenbuterol, Chloramphenicol and sulfadimidine with high sensitivity and selectivity

, , , , , ,
An accurate, rapid and cost-effective detection on the environmental hazardous chemicals is the cornerstone of efficient food safe management. Hereby we discuss the relevance of an emerging technology, multiplexed competitive immunoassays read by flow cytometry, [...]
