The prevalent nature of micro and nanoplastics (MP/NPs) on environmental pollution and health-related issues has led to the development of various methods, usually based on Fourier-transform infrared (FTIR) and Raman spectroscopies, for their detection. Unfortunately, most of the developed techniques are laboratory-based with little focus on in situ detection of MPs. In this review, we aim to give an up-to-date report on the different optical measurement methods that have been exploited in the screening of MPs isolated from their natural environments, such as water. The progress and the potential of portable optical sensors for field studies of MPs are described, including remote sensing methods. We also propose other optical methods to be considered for the development of potential in situ integrated optical devices for continuous detection of MPs and NPs. Integrated optical solutions are especially necessary for the development of robust portable and in situ optical sensors for the quantitative detection and classification of water-based MPs.

Hydrogen sulfide (H2S) plays an important role in mammals as a signaling molecule. Recently, abnormal H2S concentration has been associated with several pathophysiological states, such as diabetes mellitus, hypertension, Alzheimer’s disease, and Parkinson’s disease. As regulating H2S concentration can be a very prominent way of developing new drugs, many researchers have paid great attention to H2S research. To understand the role of H2S in pathophysiology and develop H2S-based therapies, it is necessary to measure the exact concentration of H2S within biological systems. But, H2S is volatile and can be easily oxidized. Besides, the active sites for several biological effects of H2S are inside the cell. Therefore, there is a need for the development of new methods for the accurate and reliable detection of H2S within live cells. This review provides a summary of recent developments in H2S detection methods for live cell analysis.

“…For simple, sensitive, cheap, rapid, and onsite detection capability, SERS is the future technology of interest for pesticide and antibiotics analysis [111][112][113]. Furthermore, with the development of a mass spectral library and semiconductor-metal hybrid substrates, SERS would become a robust technology for analyzing the external and penetrated pesticides of complex matrices [114].…”

Pesticides and veterinary drugs are generally employed to control pests and insects in crop and livestock farming. However, remaining residues are considered potentially hazardous to human health and the environment. Therefore, regular monitoring is required for assessing and legislation of pesticides and veterinary drugs. Various approaches to determining residues in various agricultural and animal food products have been reported. Most analytical methods involve sample extraction, purification (cleanup), and detection. Traditional sample preparation is time‐consuming labor‐intensive, expensive, and requires a large amount of toxic organic solvent, along with high probability for the decomposition of a compound before the analysis. Thus, modern sample preparation techniques, such as the quick, easy, cheap, effective, rugged, and safe method, have been widely accepted in the scientific community for its versatile application; however, it still requires a laboratory setup for the extraction and purification processes, which also involves the utilization of a toxic solvent. Therefore, it is crucial to elucidate recent technologies that are simple, portable, green, quick, and cost‐effective for onsite and infield residue detections. Several technologies, such as surface‐enhanced Raman spectroscopy, quantum dots, biosensing, and miniaturized gas chromatography, are now available. Further, several onsite techniques, such as ion mobility–mass spectrometry, are now being upgraded; some of them, although unable to analyze field sample directly, can analyze a large number of compounds within very short time (such as time‐of‐flight and Orbitrap mass spectrometry). Thus, to stay updated with scientific advances and analyze organic contaminants effectively and safely, it is necessary to study all of the state‐of‐art technology.
