Emerging electrochemical tools for microplastics remediation and sensing

Abstract

Microplastics (MPs) are a part of our daily lives and persist in the environment all across the globe. As a recently recognized emerging pollutant, there is a call to action to mitigate and monitor microplastics. Despite traditional remediation and characterization methodologies, MP-related challenges still exist. Electrochemical strategies for microplastic remediation have been reported in recent years, but very few reports exist on using electrochemical sensors for monitoring microplastics. Therefore, this minireview highlights the opportunities within the existing electrochemical remediation platforms towards sensor design and development, and elaborates on microplastic electrochemical sensors so far.

Recent Progress in Nanotechnology-Based Approaches for Food Monitoring

“…The electrochemical sensors for MNPs were widely applied to detect MP/NPs and extended to the infield testing of different types of samples without prior purification or isolation. Typical electrochemical behavior sensing of MNPs is based on label-free electrochemical impedance spectroscopy (EIS), amperometry, and voltammetry [ 246 ]. In fact, the plasticizers may migrate out of plastics into foods, which are then ingested and cause toxicological effects, such as endocrine disruption, carcinogenicity, and bioaccumulation potential [ 247 ].…”

Nanomaterial-based electrochemical chemo(bio)sensors for the detection of nanoplastic residues: trends and future prospects

“…[26][27][28][29][30] Effectively addressing the challenges posed by NPL residue pollution necessitates the deployment of quantication methods capable of assessing distribution, contamination extent, and ecological and human health impacts. [31][32][33] Although traditional analytical techniques like gas chromatography, 34 high-performance liquid chromatography, 35 and mass spectrometry 36 are accurate, they present limitations, as outlined in Table 1. In response, our research ventures into the forefront of NPL residue detection by ingeniously incorporating nanomaterial-based electrochemical techniques, thereby augmenting the capabilities of established methodologies.…”

“…However, a strategy for the rapid and “on-site” screening of micro- and nanoplastics in water samples without the need for expensive laboratory instruments and specialized staff is still in progress. Up to date, micro- and nanoplastics sensors have been developed by using electrochemical impedance spectroscopy (EIS) and amperometric and voltammetric techniques as comprehensively reported in a recent review . In addition, standing the recent developments in the fabrication of three-dimensional (3D) freeform surfaces, deformable functional sensors/circuits and standalone stretchable sensing platforms could be useful in this frame. − The development of optical sensors could provide a solution to the environmental monitoring of micro- and nanoplastics. , Huang et al proposed for the first time the use of estrogen receptor (ER) as a recognizing element for plastic particles.…”
