“…Wang et al designed a DNA aptamer which was able to detect up to four highly poisonous organo-phosphorous pesticides including phorate, profenofos, isocarbophos, and omethoateas (Shen et al, 2008). Fan et al developed an aptasensor for sensitive and selective detection of acetamiprid based on electrochemical impedance spectroscopy (Fan et al, 2013). To improve sensitivity of the aptasensor, gold nanoparticles were electrodeposited on the bare gold electrode surface by cycle voltammetry.…”

“…Aptasensors based on different types of nanomaterials in combination with electrochemical transduction output are described for the measurement of bacteria (So et al, 2008; Cella et al, 2010). Aptamer-functionalized single walled carbon nanotube field-effect transistor (SWNTFET) arrays aptasensor was developed to detect E. coli DH5 α (Fan et al, 2013). The binding between E. coli cells and the aptamer-functionalized FET resulted in a change in conductance of the samples which was subsequently related to detection mechanism.…”

Environmental contaminants monitoring is one of the key issues in understanding and managing hazards to human health and ecosystems. In this context, aptamer based electrochemical sensors have achieved intense significance because of their capability to resolve a potentially large number of problems and challenges in environmental contamination. An aptasensor is a compact analytical device incorporating an aptamer (oligonulceotide) as the sensing element either integrated within or intimately associated with a physiochemical transducer surface. Nucleic acid is well known for the function of carrying and passing genetic information, however, it has found a key role in analytical monitoring during recent years. Aptamer based sensors represent a novelty in environmental analytical science and there are great expectations for their promising performance as alternative to conventional analytical tools. This review paper focuses on the recent advances in the development of aptamer based electrochemical sensors for environmental applications with special emphasis on emerging pollutants.

“…Acetamiprid is a kind of neonicotinoid class with relatively low chronic mammalian toxicity, but it still could generate potential health risk of human beings when exposed to the primary route of the polluted food, water and environments [23,24]. Therefore, it is highly desirable to develop a simple, highly sensitive and selective method for quantification of acetamiprid residues in food and environment to keep people from potential health risk.…”

“…As it can be deduced for data summarized in Table 2, several recently reported immunosensors and aptasensors for pesticides make use of electrochemical impedance spectroscopy as electrochemical transduction technique. For example, Fan et al [80] developed an aptasensor for the detection of acetamiprid, a new neonicotinoid systemic broad-spectrum insecticide used to replace organophosphorous and other insecticides. A gold electrode modified with AuNPs was used to immobilize the aptamer and EIS was employed to measure the changes in the electron transfer resistance related with complexation with different analyte concentrations.…”

Safety and quality are key issues of today's food industry. Since the food chain is becoming more and more complex, powerful analytical methods are required to verify the performance of food safety and quality systems. Indeed, such methods require high sensitivity, selectivity, ability for rapid implementation and capability of automatic screening. Electroanalytical chemistry has, for decades, played a relevant role in food safety and quality assessment, taking more and more significance over time in the solution of analytical problems. At present, the implementation of electrochemical methods in the food is evident. This is in a large part due to the relevant results obtained by combining the attractive advantages of electrochemical transduction strategies (in terms of relatively simple hardware, versatility, interface with automatic logging and feasibility of application outside the laboratory environment) with those from biosensors technology. Important examples of enzyme electrochemical biosensors are those dedicated to the determination of glucose, alcohol or cholesterol are important examples. In addition, other types of different electrochemical biosensing approaches have emerged strongly in the last years. Among these, the strategies involving affinity interactions have been shown to possess a large number of applications. Therefore, electrochemical immunosensors and DNA-based biosensors have been widely used to determine major and minor components in foodstuffs, providing sufficient data to evaluate food freshness, the quality of raw materials, or the origin of samples, as well as to determine a variety of compounds at trace levels related to food safety such as micotoxins, allergens, drugs residues or pathogen microorganisms. This review discusses some critical examples of the latest advances in this area, pointing out relevant methodologies related to the measurement techniques, including the use of nanostructured electrodes and strategies for signal amplification.
