Special Issue Information

Dear Colleagues,

One of the major challenges to be resolved by researchers is the design and development of reliable high sensitivity and low-cost sensors using novel nanoparticulate materials. The low dimensionality of nanoparticles results in excellent physicochemical properties (e.g., ease of functionalization via simple chemistry and high surface-to-volume ratios) which, allied with their unique spectral and optical properties, have prompted the development of a plethora of (bio)sensing platforms. Particularly, the incorporation of nanoparticulate materials in electrochemical devices notably provides benefits such as large specific surface area, high electrical conductivity, and low charge transfer resistance, which considerably improves electroanalytical properties such as high sensitivity and low limits of detection, among others. Nanoparticle-based sensors are gaining advantages in low cost point-of-care analysis of real samples, which involves complex sample matrices and even the need for wireless communications. For that reason, this Special Issue is intended to provide the most recent research results and emerging concepts in the challenging world of nanoparticles-based (bio)electrochemical sensors. The Special issue faces facile, sustainable scalable fabrication of nanostructured surface-based sensors using cutting-edge techniques such as screen or 3D printing technologies, looking for improving selectivity, fast response, long-term stability, and biocompatibility. Applications of nanomaterial-modified sensors for detection of relevant compounds in different fields such as the environment, clinical diagnostics, food quality control, and biowarfare are also welcome. Research papers, short communications, letters, and reviews will be considered for publication.

Therefore, potential topics include but are not limited to the following:

  • Synthesis and characterization of novel nanostructured materials for (bio)sensing applications;
  • Stability and selectivity of composite nanoparticles in complex media;
  • Long-term stability without regular maintenance;
  • New insights in synergistic phenomena in terms of sensing properties;
  • Applications of nanoparticle-based (bio)sensors.

Herein, a novel electrochemical glucose biosensor based on glucose oxidase (GOx) immobilized on a surface containing platinum nanoparticles (PtNPs) electrodeposited on poly(Azure A) (PAA) previously electropolymerized on activated screen-printed carbon electrodes (GOx-PtNPs-PAA-aSPCEs) is reported. The resulting electrochemical biosensor was validated towards glucose oxidation in real samples and further electrochemical measurement associated with the generated H2O2. The electrochemical biosensor showed an excellent sensitivity (42.7 μA mM−1 cm−2), limit of detection (7.6 μM), linear range (20 μM–2.3 mM), and good selectivity towards glucose determination. Furthermore, and most importantly, the detection of glucose was performed at a low potential (0.2 V vs. Ag). The high performance of the electrochemical biosensor was explained through surface exploration using field emission SEM, XPS, and impedance measurements. The electrochemical biosensor was successfully applied to glucose quantification in several real samples (commercial juices and a plant cell culture medium), exhibiting a high accuracy when compared with a classical spectrophotometric method. This electrochemical biosensor can be easily prepared and opens up a good alternative in the development of new sensitive glucose sensors. Full article
