“…A biosensor typically consists of an analyte in a sample, a bioreceptor (biorecognition element), a transducer and a signal amplification and analysis circuit (Koyun et al, 2012). The analyte is dispersed in the sample with other molecules.…”

“…The analyte is dispersed in the sample with other molecules. The bioreceptor is immobilised with a biomaterial selective to the (Koyun et al, 2012). The transducer converts the signal from the analyte, reacts with the biorecognition element and is interpreted by the signal analysis circuit (Sassolas et al, 2012).…”

“…Biosensors are usually highly specific due to the use of selected biorecognition elements and are integrated with existing technology to produce highly robust, low-cost, portable devices (Koyun et al, 2012). Biosensors are thus ideally suited to monitor the microbiological quality of water and the efficiency of filters or membranes in water treatment plants.…”

“…These include that heat sterilisation is not possible due to denaturisation of the biomaterial, biomaterial stability is dependent on the natural properties of the material and environmental conditions, and the cells in the biosensor can become contaminated by other unwanted molecules (Koyun et al, 2012).…”

The supply of safe potable water, free from pathogens and chemicals, requires routine analyses and the application of several diagnostic techniques. Apart from being expensive, many of the detection methods require trained personnel and are often time-consuming. With drastic climate changes, severe droughts, increases in population and pollution of natural water systems, the need to develop ultrasensitive, low-cost and hand-held, point-of-use detection kits to monitor water quality is critical. Although Escherichia coli is still considered the best indicator of water quality, cell numbers may be below detection limits, or the cells may be non-culturable and thus only detected by DNA amplification. A number of different biosensors have been developed to detect viable, dead or non-culturable microbial cells and chemicals in water. This review discusses the differences in these biosensors and evaluates the application of microfluidics in the design of ultra-sensitive nano-biosensors.

“…The detection capacity of the electrochemical biosensor can be affected by the electrode surface dimension, its material, and modifications. 22 Three different types of electrodes are used in the electrochemical biosensor, ie, reference electrode, working electrode, and auxillary (counter) electrode.…”

Abstract:In recent years, food storage environment safety has been a major concern for food and health scientists. There is growing interest in electrochemical biosensors due to their high sensitivity and rapid response. The aim of this review article is to provide details regarding the development of enzyme-based electrochemical biosensors, and their use in the detection of a range of chemical and biological compounds in the food industry. We have focused on the basic principle, generation, classification, and application of electrochemical biosensors for food safety.

Sensors, components of direct‐reading instruments that provide high temporal resolution information on physical and chemical agents, are becoming increasingly common for industrial hygiene practice. Sensors can be included in a wide variety of instruments, ranging in cost from hundreds to tens of thousands of dollars. Users of sensors must have a clear understanding of the principles of operation and biases of each sensor to evaluate if it is fit for the purpose under the desired conditions, and to ensure data are interpreted with maximum reliability. This chapter describes the principles of operation, advantages, and disadvantages of commonly used particulate matter, gas, and physical agent sensors, with a focus on low‐cost technologies. The chapter concludes with a description of opportunities for sensors in industrial hygiene practice. Although there are limitations with the use of sensors for compliance monitoring, sensors provide an opportunity to better capture the spatial and temporal variability of agents and to identify effective control strategies.
