Biosensors are increasingly vital for real-time environmental and food safety monitoring, offering rapid, sensitive, and specific detection of contaminants. This review highlights recent advancements in biosensor technologies, including electrochemical, optical, and piezoelectric platforms, tailored for detecting pesticides, heavy metals, pathogens, and toxins. Key insights point to the integration of nanomaterials and advanced biomolecular recognition elements significantly enhancing sensor performance, paving the way for portable and cost-effective solutions for on-site analysis [1].
This research focuses on the development of electrochemical immunosensors for the sensitive detection of a specific pesticide in agricultural runoff. The study details the fabrication of a screen-printed electrode modified with gold nanoparticles and an anti-pesticide antibody. The resulting sensor demonstrated excellent sensitivity and selectivity, with a limit of detection in the low ppb range, making it suitable for rapid field screening [2].
The paper presents a novel optical biosensor based on surface plasmon resonance (SPR) for the detection of heavy metal ions in drinking water. By functionalizing the SPR sensor surface with specific chelating ligands, the sensor achieved high selectivity and rapid response times for lead and cadmium. The potential for multiplexed detection of various heavy metals in a single assay is also discussed [3].
This study explores the use of aptamer-based biosensors for the rapid identification of pathogenic bacteria in food matrices. Aptamers, short nucleic acid sequences, offer high specificity and stability. The research demonstrates a microfluidic device integrating aptasensors for detecting Salmonella and E. coli in raw milk with a detection limit in the range of 10^3 CFU/mL, offering a promising alternative to traditional culture methods [4].
A paper detailing the application of DNA-based biosensors for the detection of mycotoxins in cereals. The biosensor utilizes DNA probes immobilized on a graphene oxide surface, coupled with electrochemical detection. High sensitivity and selectivity for aflatoxin B1 were achieved, with detection limits well below regulatory thresholds, highlighting its potential for quality control in the food industry [5].
This review critically examines the challenges and opportunities in developing portable biosensors for food safety. It discusses the integration of microfluidics, novel transducer technologies, and signal amplification strategies to create on-site, rapid detection systems. Emphasis is placed on user-friendliness, cost-effectiveness, and regulatory acceptance for widespread adoption [6].
A study on the use of enzymatic biosensors for the detection of organophosphate pesticides in fruits and vegetables. Immobilized acetylcholinesterase enzyme on an amperometric electrode was employed. The sensor showed good sensitivity and stability, enabling the detection of several common organophosphates at trace levels, important for ensuring food safety [7].
This work presents a colorimetric aptasensor for the detection of lead ions in environmental water samples. The aptasensor utilizes gold nanoparticles modified with DNA aptamers that specifically bind to lead ions. Upon binding, the aggregation state of the gold nanoparticles changes, resulting in a visible color change that can be quantified using a simple spectrophotometer, offering a low-cost and rapid detection method [8].
The article describes the development of a sensitive electrochemical biosensor for the detection of microcystins, a common type of cyanotoxin found in water bodies. The biosensor employs an antibody-antigen recognition strategy immobilized on a modified electrode. The fabricated biosensor achieved a low detection limit for microcystin-LR, indicating its potential for monitoring harmful algal blooms and water quality [9].
This paper investigates the application of smartphone-based biosensors for on-site detection of foodborne pathogens. It showcases a system that uses a smartphone camera to analyze the color change from a reagent-based assay or the fluorescence signal from a biosensor. This approach offers a low-cost, portable, and user-friendly solution for rapid food safety testing in diverse settings [10].
