“…Inkjet printing, 3D printing, and screen printing are the most common methods for printing electrodes and are widely employed to create planar electrodes for electrochemical sensing. 86,87 Screen-printed electrodes (SPEs) are single-use electrodes that are cost-effective and are fabricated in large quantities. These electrodes are user-friendly and do not require any preprocessing or specialized personnel.…”

“…In particular, an SERS substrate in a PDMS microfluidic channel, using silver nanostructures inside the microfluidic channel, for the rapid detection of Hg ions compared to conventional SERS devices, was fabricated. This device can detect Hg ions in aqueous solutions with a high sensitivity and good selectivity, and the reported LOD is 1 × 10 −7 M. W. Zhang et al [ 97 ] have also achieved the detection of Hg 2+ using a localized surface plasmon resonance (LSPR) nanosensor and a microfluidic chip made from PDMS, which is bonded with a cover glass. This device, with nanostructures formed by nanorods, can monitor Hg 2+ in real-life water samples with an LOD of 2.7 pM.…”

The contamination of air, water and soil by heavy metal ions is one of the most serious problems plaguing the environment. These metal ions are characterized by a low biodegradability and high chemical stability and can affect humans and animals, causing severe diseases. In addition to the typical analysis methods, i.e., liquid chromatography (LC) or spectrometric methods (i.e., atomic absorption spectroscopy, AAS), there is a need for the development of inexpensive, easy-to-use, sensitive and portable devices for the detection of heavy metal ions at the point of interest. To this direction, microfluidic and lab-on-chip (LOC) devices fabricated with novel materials and scalable microfabrication methods have been proposed as a promising approach to realize such systems. This review focuses on the recent advances of such devices used for the detection of the most important toxic metal ions, namely, lead (Pb), mercury (Hg), arsenic (As), cadmium (Cd) and chromium (Cr) ions. Particular emphasis is given to the materials, the fabrication methods and the detection methods proposed for the realization of such devices in order to provide a complete overview of the existing technology advances as well as the limitations and the challenges that should be addressed in order to improve the commercial uptake of microfluidic and LOC devices in environmental monitoring applications.

“…Liu et al designed a core–satellite-structured plasmonic combined with microfluidic technology to achieve in situ trace detection of Hg 2+ , as shown in Figure 19 [ 45 ]. The plasmonic consists of a AuNR with an aspect ratio of 2.5:1 (length: 37 nm; width: 10 nm) as a core, and a AuNP with a diameter of 10 nm as the satellite part.…”

Plasma nanoparticles offer promise in data storage, biosensing, optical imaging, photoelectric integration, etc. This review highlights the local surface plasmon resonance (LSPR) excitation mechanism of plasmonic nanoprobes and its critical significance in the control of dark-field sensing, as well as three main sensing strategies based on plasmonic nanomaterial dielectric environment modification, electromagnetic coupling, and charge transfer. This review then describes the component materials of plasmonic nanoprobes based on gold, silver, and other noble metals, as well as their applications. According to this summary, researchers raised the LSPR performance of composite plasmonic nanomaterials by combining noble metals with other metals or oxides and using them in process analysis and quantitative detection.
