The in situ DNA-damaging capacity of berenil (1) has been investigated usingan electrochemical approach employing double stranded (ds) DNA-modified glassy carbonelectrode biosensors. Electrochemical voltammetric sensing of damage caused by 1 todsDNA was monitored by the appearance of peaks diagnostic of the oxidation of guanineand adenine. When 1 was incorporated directly onto the biosensor sur...
We report on a novel approach to predict the mode of genotoxic action of chemicals using a series of DNA damage specific bioluminescent bacteria. For this, a group of seven different DNA damage sensing recombinant bioluminescent strains were employed. Each of these strains was tested against model DNA damaging agents, such as mitomycin C (MMC), 1-methyl-1-nitroso-N-methylguanidine (MNNG), nalid...
MicroRNAs are widely studied as circulating biomarkers for early stage diagnosis of several diseases. Detection and quantification miRNAs is currently performed through complex time consuming procedures. Herein we demonstrate a rapid, multiplex, one-pot detection method based on two-step amplification the signal measured by Reflective Phantom Interface (RPI) label-free optical biosensor. We ach...
Identification of Chinese Herbs Using a Sequencing-Free Nanostructured Electrochemical DNA Biosensor
Due to the nearly identical phenotypes and chemical constituents, it is often very challenging to accurately differentiate diverse species of a Chinese herbal genus. Although technologies including DNA barcoding have been introduced to help address this problem, they are generally time-consuming and require expensive sequencing. Herein, we present a simple sequencing-free electrochemical biosen...
