State-of-the-Art of (Bio)Chemical Sensor Developments in Analytical Spanish Groups

Abstract

(Bio)chemical sensors are one of the most exciting fields in analytical chemistry today. The development of these analytical devices simplifies and miniaturizes the whole analytical process. Although the initial expectation of the massive incorporation of sensors in routine analytical work has been truncated to some extent, in many other cases analytical methods based on sensor technology have solved important analytical problems. Many research groups are working in this field world-wide, reporting interesting results so far. Modestly, Spanish researchers have contributed to these recent developments. In this review, we summarize the more representative achievements carried out for these groups. They cover a wide variety of sensors, including optical, electrochemical, piezoelectric or electro-mechanical devices, used for laboratory or field analyses. The capabilities to be used in different applied areas are also critically discussed.

UV-patternable nanocomposite containing CdSe and PbS quantum dots as miniaturized luminescent chemo-sensors

“…The design of low-cost, easy-tofabricate and portable analytical devices with a low limit of detection (LOD), good selectivity, high sensitivity and short response time are in high demand. [1][2][3] Part of that has been made possible by the use of nanomaterials. In particular, (bio) chemical sensors based on uorescent quantum dots (QDs) have attracted intense interest because of their excellent optical and electronic properties compared to the routinely employed uorescent organic dyes.…”

Advances in Electrochemical Nano-Biosensors for Biomedical and Environmental Applications: From Current Work to Future Perspectives

“…Conventional methods for chemical analysis offer many advantages, including their high accuracy and acceptable sensitivity. However, those analytical methods, in many cases, require complex instruments, high expensive reagents, large sample consumption, and lack of portability and cannot support on-site monitoring, and a lab specialist with high skills is required [ 1 ]. Hence, there is a need for developing chemical sensors and biosensors.…”

Nano-Aptasensing in Mycotoxin Analysis: Recent Updates and Progress

“…The presence of well-developed synthesis methods for nanomaterials (e.g., noble metal, magnetic, and metal oxide nanoparticles) offers a wide range of selection options for the right employment of the sensing element in the aptasensing design. Due to their small size (1–100 nm), these nanoparticles possess unique optical, chemical, and electronic properties that differs from their bulk materials, promoting their use in the aptasensors [ 44 ]. The majority of the nano-aptasensors developed up to date are based on noble metal nanoparticles due to their unique physicochemical properties [ 45 ].…”
