Electrochemical DNA- and Aptasensors for the Detection of Low-Molecular Compounds

Dear Colleagues,

Electrochemical DNA and aptasensors have attracted increasing attention in the past few decades due to the fruitful promise of applications in the framework of point-of-care (point-on-demand) concepts outside the chemical laboratory. They are intended for the fast and reliable detection of many species demanded in medicine (metabolites, drugs, oncomarkers), the food industry (vitamins, antioxidants, food additives, veterinary drugs) and environmental monitoring (pesticides, DNA damaging contaminants, heavy metals, detergents). Assembly of the DNA sensors, including design of biorecognition elements and new approaches to the signal amplification, calls for new materials based on the achievements of supramolecular chemistry, nanotechnology and self-assembly. In this Special Issue, the following topics are welcome, as either reviews or research articles:

• The design of DNA and aptasensors based on new modifiers and assembly protocols (carbon nanomaterials, MOFs, MIPs, polyelectrolyte layers, hybrid coatings with metals and compounds (oxides, complexes)
• Application of new mediator systems to enhance the electrochemical signals and development of robust biosensors
• Biochemical systems of signal amplification and E-sensor design
• Multiplex analysis with electrochemical DNA and aptasensors
• Miniaturization and automation prospects for low-molecular-weight analyte detection, electrochemical microfluidics and flow-injection analysis and origami biosensors
• Sampling and sample treatment, and validation of electrochemical DNA and aptasensors for real sample analysis
• Future prospects in the design of biorecognition elements (chimeric DNA, protein nucleic acids, hybrid immuno/DNA sensors)

The topic of this manuscript expected to be published in the Special Issue, “Electrochemical DNA and Aptasensors for the Detection of Low-Molecular-Weight compounds”, coincides well with the scope of the Sensors journal because it covers all the important steps in biosensor assembly and use, including the recognition elements, surface layer assembly, measurement condition optimization and real sample assay problems. Portable sensor design is one of the burning topics in modern science because of obvious benefits in their application and possible advantages from their innovation.
