PRLog - Jan. 23, 2014 - BOSTON -- www.knowledgefoundation.com

BIODETECTION TECHNOLOGIES 2014 - the 22nd conference in our Detection Technologies conference series - is an internationally recognized meeting for experts in detection & identification of biological threats and point-of-care analytical methods. This conference will review feedback from the end-users on biodefense and biomedical technologies and explore the cutting-edge in R&D and commercialization efforts in the field, including:

•    Rapid biosensing, biodetection and analysis
•    Simultaneous detection of multiple threats and pathogens
•    Discovery and analysis of biosignatures for the detection of host response
•    Point-of-care/clinical applications for pathogen/virus/threat detection and identification
•    Point-of-care assays for resource limited, lab and clinical settings; mobile labs
•    Advances in microarray and sequencing technologies
•    Field-deployable devices: portability/compatibility/reliability/scalability
•    Non-PCR vs. PCR based detection techniques
•    Issues of sensitivity/testing/evaluation/validation
•    Animal and plant pathogens
•    Bioelectronics
•    DNA chips, nucleic acid sensors and aptasensors
•    Enzyme-based biosensors
•    Immunosensors
•    Lab-on-a-chip
•    Microfluidics and immobilisation technology
•    Natural & synthetic receptors (including MIPs)
•    Organism- and whole cell-based biosensors
•    Proteomics, single-cell analysis and cancer-cell detection

•    Signal transduction technology (including magneto, piezo, optical and direct electrochemical techniques)

FEATURED PRESENTATION:

Towards PCR-Free, Visual DNA Detection

Mahesh Uttamchandani, PhD, Assistant Professor, DSO National Laboratories, National University of Singapore, Singapore

We describe novel methods to detect DNA sequence specifically through color change reactions. To transduce molecular recognition events into visual readouts, we have engineered assays which have exploited split DNAzymes and gold nanoparticles. The G-quadruplex DNAzymes were successfully applied to the detection of Salmonella and Mycobacterium DNA, as well as in genotyping a single base difference from within human genomic DNA samples. This was the first time the approach was demonstrated starting from live genomic DNA samples. An integrated workflow was capable of detecting DNA samples through a color change within just 5-15 min (3). The gold nanoparticle method offered much greater sensitivity, enabling the detection of as little as 608 000 copies of the Salmonella genome, by eye, without the need for PCR amplification. These methods thus enable direct on-site visual detection, by bringing sophisticated DNA analysis capabilities to the point of care setting, without the need for cumbersome equipment or a power source.
