Sustainable cultivation and safe agricultural production are needed to ensure the safety of all living organisms and ecosystems. Most agricultural foods currently contain unacceptable levels of pesticide residues. In an attempt to ensure pest control and high crop yields, farmers spray a large number of pesticides in quantities that exceed the safety limits for agricultural crops. Pesticide residues are highly toxic to humans, causing severe and even deadly diseases. Traditional analytical strategies for laboratory pesticide detection are often limited because they are time-consuming and require trained personnel, which makes them very costly. Hence, accurate, rapid, and on-site analysis of pesticides is drawing increasing attention for food safety reasons. Therefore, on-site or point-of-care (POC) detection of pesticide residues has become an approach of paramount importance. Recently, various portable detection technologies, such as colorimetric, fluorescence, electrochemical, surface plasmon resonance, chemiluminescence, phosphorescence, microfluidic, and surface-enhanced Raman scattering techniques, have been designed for on-site monitoring of pesticide residues in vegetables and fruits. These devices have demonstrated great power of detection in preclinical agricultural settings. This review highlights the emerging insights and novel advances in portable devices, POC technologies, and on-site sensing approaches for the detection of pesticide residues in agricultural foods. However, greater rigor in the design of portable pesticide-detection devices is essential.The increasing demand for rapid detection of hazardous pesticide components has prompted a timely opportunity to summarize recent developments and progress in portable devices and on-site sensing strategies to evaluate food safety.

“…So far, many detection methods have been developed for the detection of the tau protein, including surface plasmon resonance (SPR) [ 7 , 8 ], surface-enhanced Raman spectroscopy (SERS) [ 9 ], field-effect transistors [ 10 , 11 ], colorimetry [ 12 ], fluorescence [ 13 , 14 ], and electrochemistry [ 15 , 16 , 17 ]. Among these methods, a portable electrochemical biosensor has tremendous potential for home health monitoring and personal healthcare due to its easy miniaturization, high sensitivity, and low cost [ 18 , 19 , 20 , 21 , 22 ]. A portable biosensor can be particularly significant as home health monitoring and personal healthcare become more and more common during the COVID-19 pandemic [ 23 , 24 ].…”

Alzheimer’s disease (AD) is a long-term neurodegenerative disease that poses a serious threat to human life and health. It is very important to develop a portable quantitative device for AD diagnosis and personal healthcare. Herein, we develop a portable electrochemical sensing platform for the point-of-care detection of AD biomarkers in the blood. Such a portable platform integrates nanoAu-modified vertical graphene (VG@Au) into a working electrode, which can significantly improve sensitivity and reduce detection limit due to the large specific surface, excellent electrical conductivity, high stability, and good biocompatibility. The tau protein, as an important factor in the course of AD, is selected as a key AD biomarker. The results show that the linear range of this sensing platform is 0.1 pg/mL to 1 ng/mL, with a detection limit of 0.034 pg/mL (S/N = 3), indicating that this portable sensing platform meets the demand for the detection of the tau protein in the blood. This work offers great potential for AD diagnosis and personal healthcare.

“…The current mainstream is optical analysis. Compared with traditional optical analysis methods, detection methods based on spectra such as X-ray Fluorescence spectrometry (XRF, the limit of detection of Cd (II) is generally 2~5 mg/kg) [ 12 , 13 , 14 ] and visible near-infrared spectrum (Vis-NIR, characteristic bands: 400~600 nm, 979 nm, 2206 nm; relative error: 30~40%) [ 15 , 16 ] are characterized by rapid, simple, portable, and non-destructive testing [ 17 , 18 ]. However, due to its high limit of detection and certain errors, it is difficult to obtain obvious spectral lines when using spectral technology to analyze the Cd content in soil.…”

Cadmium (Cd) pollution in soil is a serious threat to food security and human health, while, currently, the most widely used detection methods cannot accurately reflect the content of heavy metals in soil. Soil heavy metal detection combined with microelectronic sensors has become an important means of environmental heavy metal pollution prevention and control. X-ray Fluorescence spectrometry (XRF) can capture the excitation spectrum of metal elements, which is often used to detect Cd (II). However, due to the lack of high-performance optoelectronic devices, the analysis accuracy of the system cannot meet the requirements. Therefore, this study proposes a high-detection-efficiency photodiode (HDEPD) which can effectively improve the detection accuracy of the analyzer. The HDEPD is manufactured based on a 0.18 μm standard complementary metal-oxide-semiconductor (CMOS) process. The volt-ampere curve, spectral response and noise characteristics of the device are obtained by constructing a test circuit combined with a spectral detection system. The test results show that the threshold voltage of HDEPD is 12.15 V. When the excess bias voltage increases from 1 V to 3 V, the spectral response peak of the device appears at 500 nm, and the photon detection probability (PDP) increases from 41.7% to 52.8%. The dark count rate (DCR) is 31.9 Hz/μm2 at a 3 V excess bias voltage. Since the excitation spectrum peak of Cd (II) is between 500 nm and 600 nm, the wavelength response range of HDEPD fully meets the detection requirements of Cd (II).
