Special Issue Information

Dear Colleagues,

Biosensors have earned considerable interest in recent years, and they show great promise for a wide range of applications in biological research, medical diagnostics, environmental or food industry monitoring. Making use of the synergetic effect between nanotechnology, biomolecules and different detection methods has enabled nanobiosensors development for faster detection and its reproducibility in a much better way.

We invite, for this “NanoBioSensors for Biomedical, Environmental and Food Monitoring Applications” Special Issue, manuscripts dealing with different detection methods-based nanobiosensors for application fields mentioned above, while not being limited to those, which will be or not presented in the frame of the International Conference, IC-ANMBES 2018, held in Brasov, Romania (https://sciforum.net/conference/icanmbes2018). Both original research and review articles are welcome.

Original research papers that describe the development, characterization/evaluation, simulations and utilization of different architectures (sensor, fixed, mobile) platforms for detection of biological active or toxic compounds in complex samples with potential applications in medical analysis and diagnosis, environmental or food industry monitoring are of interest. The manuscripts can deal with next topics (but are not limited to) with potential relevance to nanobiosensing:

- microfluidics and point-of-care microdevices,
- optical fibers,
- mass-sensitive chips,
- novel materials electrodes and surface functionalization strategies applications or
- new concepts and fundamental studies.

Reviews should provide an up-to-date and critical overview of state-of-the-art of platforms and detection mechanisms, especially those used for nanobiosensing.

Please feel free to contact us and send us your suggestions that you would like to discuss beforehand. We look forward to and welcome your participation in this Special Issue.

In this study, a new electrochemical sensor was developed for the detection of cefalexin (CFX), based on the use of a molecularly imprinted polymer (MIP) obtained by electro‒polymerization in an aqueous medium of indole-3-acetic acid (I3AA) on a glassy carbon electrode (GCE) and on boron-doped diamond electrode (BDDE). The two different electrodes were used in order to assess how their structural differences and the difference in the potential applied during electrogeneration of the MIP translate to the performances of the MIP sensor. The quantification of CFX was performed by using the electrochemical signal of a redox probe before and after the rebinding of the template. The modified electrode was characterized using atomic force microscopy (AFM), scanning electron microscopy (SEM), cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). The influence of different parameters on the fabrication of the sensor was tested, and the optimized method presented high selectivity and sensitivity. The MIP-based electrode presented a linear response for CFX concentration range of 10 to 1000 nM, and a limit of detection of 3.2 nM and 4.9 nM was obtained for the BDDE and the GCE, respectively. The activity of the sensor was successfully tested in the presence of some other cephalosporins and of other pharmaceutical compounds. The developed method was successfully applied to the detection of cefalexin from real environmental and pharmaceutical samples. Full article
