Food analysis is significantly important in monitoring food quality and safety for human health. Traditional methods for food detection mainly rely on benchtop instruments and require a certain amount of analysis time, which promotes the development of portable sensors. Portable sensing methods own many advantages over traditional techniques such as flexibility and accessibility in diverse environments, real‐time monitoring, cost‐effectiveness, and rapid deployment. This review focuses on the portable approaches based on carbon dots (CDs) for food analysis. CDs are zero‐dimensional carbon‐based material with a size of less than 10 nm. In the manner of sensing, CDs exhibit rich functional groups, low biotoxicity, good biocompatibility, and excellent optical properties. Furthermore, there are many methods for the synthesis of CDs using various precursor materials. The incorporation of CDs into food science and engineering for enhancing food safety control and risk assessment shows promising prospects.

Enhancing the selectivity of detection methods is essential to distinguish breast cancer biomarker cluster of differentiation 44 (CD44) from other species and reduce false-positive or false-negative results. Here, oxygen vacancy-enriched CoFe 2 O 4 (CoFe 2 O 4−x ) was crafted, and its implementation as an electrochemical electrode for the detection of CD44 biomarkers has been scrutinized. This unique electrode material offers significant benefits and novel features that enhance the sensitivity and selectivity of the detection process. The oxygen vacancy density of CoFe 2 O 4−x was tuned by adjusting the mass ratios of iron to cobalt precursors (iron−cobalt ratio) and changing annealing atmospheres. Electrochemical characterization reveals that, when the iron−cobalt ratio is 1:0.54 and the annealing atmosphere is nitrogen, the as-synthesized CoFe 2 O 4−x electrode manifests the best electrochemical activity. The CoFe 2 O 4−x electrode demonstrates high sensitivity (28.22 μA (ng mL) −1 cm −2 ), low detection limit (0.033 pg mL −1 ), and robust stability (for 11 days). Oxygen vacancies can not only enhance the conductivities of CoFe 2 O 4 but also provide better adsorption of −NH 2 , which is beneficial for stability and electrochemical detection performance. The electrochemical detection signal can be amplified using CoFe 2 O 4−x as a signal probe. Additionally, it is promising to know that the CoFe 2 O 4−x electrode has shown good accuracy in real biological samples, including melanoma cell dilutions and breast cancer patient sera. The electrochemical detection results are comparable to ELISA results, which indicates that the CoFe 2 O 4−x electrode can detect CD44 in complex biological samples. The utilization of CoFe 2 O 4−x as the signal probe may expand the application of CoFe 2 O 4−x in biosensing fields.

Ballast water, which is seawater taken onboard ships to ensure stable and maneuverable sailing, can pose a significant threat to marine ecosystems and human health when discharged owing to the presence of undesirable organisms. To mitigate this risk, ballast water treatment methods such as electrochlorination are employed, where oxidants such as hypochlorite are generated to effectively eliminate marine microorganisms. The effectiveness of an electrochlorination‐based ballast water management system (BWMS) depends on the maintenance of optimal concentrations of total residual chlorine (TRC). However, excessive levels of free chlorine (Cl) can result in corrosion and environmental damage, rendering the accurate monitoring of TRC levels crucial for the safe discharge of ballast water. This review focuses on recent advancements in electrochemical sensors for free Cl measurement in BWMS. The process of free Cl generation, techniques for electrochemical detection, and factors influencing sensor performance are elucidated. In addition, materials and strategies for improving the performance of the sensors are described. Finally, perspectives on the current issues and future challenges that must be overcome to effectively utilize electrochemical detection in BWMS are discussed, thereby offering new directions for advancing this technology.
