“…These features were exploited to construct a portable mini-photothermal device capable of colorimetric and fluorescent GLP determination in the 0.039−3.19 μg/mL LDCR with the LOD of 0.0131 μg/mL and the 0.0088−3.98 μg/mL LDCR with the LOD of 0.0015 μg/mL, respectively. 128 Because of the analyte-triggered AChE inhibition, the optical sensors for GLP, based on the single molecule "turn on/off" on-site sensing mode, belong to the most sensitive and selective. Future optical technologies, compatible with smartphone-assisted kits and LOCs, include paper-, liquid-, and gel-based sensors.…”

The present article critically and comprehensively reviews the most recent reports on smart sensors for determining glyphosate (GLP), an active agent of GLP-based herbicides (GBHs) traditionally used in agriculture over the past decades. Commercialized in 1974, GBHs have now reached 350 million hectares of crops in over 140 countries with an annual turnover of 11 billion USD worldwide. However, rolling exploitation of GLP and GBHs in the last decades has led to environmental pollution, animal intoxication, bacterial resistance, and sustained occupational exposure of the herbicide of farm and companies' workers. Intoxication with these herbicides dysregulates the microbiomegut-brain axis, cholinergic neurotransmission, and endocrine system, causing paralytic ileus, hyperkalemia, oliguria, pulmonary edema, and cardiogenic shock. Precision agriculture, i.e., an (information technology)-enhanced approach to crop management, including a site-specific determination of agrochemicals, derives from the benefits of smart materials (SMs), data science, and nanosensors. Those typically feature fluorescent molecularly imprinted polymers or immunochemical aptamer artificial receptors integrated with electrochemical transducers. Fabricated as portable or wearable lab-on-chips, smartphones, and soft robotics and connected with SM-based devices that provide machine learning algorithms and online databases, they integrate, process, analyze, and interpret massive amounts of spatiotemporal data in a user-friendly and decision-making manner. Exploited for the ultrasensitive determination of toxins, including GLP, they will become practical tools in farmlands and point-of-care testing. Expectedly, smart sensors can be used for personalized diagnostics, real-time water, food, soil, and air quality monitoring, site-specific herbicide management, and crop control.

“…Nevertheless, individual colorimetric sensors are generally limited in sensitivity and susceptible to inaccurate readings due to the interference of environmental factors. The integration of colorimetric signals with other sensing modes for a multiple signal integration platform can utilize the visualization of colorimetric modes, and the integration of quantitative modes with different sensitivities can enhance the overall applicability [ 19 ]. Additionally, the dual-mode analysis strategy can provide an inbuilt cross-reference correction for environmental impacts through reciprocal validation among different patterns for enhanced dependability [ 20 ].…”

In recent years, the high prevalence of Salmonella has emerged as a serious threat to public safety, prompting attempts to utilize accurate, rapid, and direct methods to ensure food safety. In this study, a multifunctional platform featuring dual-mode detection channels (colorimetric-fluorescence) combined with polymer chain reaction (PCR) was proposed for the sensitive and rapid detection of Salmonella. Additionally, the colorimetric measurements were achieved by color changes induced by methylene blue (MB) insertion into the double-stranded DNA, and the fluorescence measurements were performed by internal filter effect (IFE)-induced fluorescence quenching of upconversion nanoparticles (UCNPs) by MB. The results showed that the IFE and PCR amplification processes improved the sensitivity of the sensor towards Salmonella detection, with a limit of detection (LOD) of 21.8 CFU/mL. Moreover, this colorimetric-fluorescence dual-mode PCR biosensor was applied to determine Salmonella in food samples, such as chicken, egg, and fish, which produced satisfactory results. Overall, the present study results demonstrate the potential for combining PCR amplification with IFE to develop an efficient and reliable dual-mode analysis platform to safeguard food security.

“…However, such single-channel strategies usually have limited sensitivity and are susceptible to interference from environmental factors, thereby leading to inaccurate readings. 44 Employment of doped CDs as nanozymes ensures that their own inherent photoluminescence can be provided, which makes it possible to combine colorimetric signals with FL (especially FL ratio) to build a dual-mode detection platform and improve the sensing performance greatly. Compared with single-signal detection, a two-channel method introduces various quantitative modes with different sensitivities, and can integrate the advantages of these modes skillfully.…”
