“…Nevertheless, complicated pretreatment processes, expensive instruments and professional operator requirements make these methods not suitable to routine and rapid analysis of samples. Alternatively, electrochemical method has the advantages of rapid analysis, cheap equipment and simple operation [8,9]. Thus many electrochemical sensors for CAP detection based on various electrode materials have been developed [10][11][12][13][14][15][16][17].…”

A green but efficient synthesis approach for chlorine-doped reduced graphene oxide (Cl-RGO) was developed. The chlorine-doping and reduction was achieved in one-step by refluxing graphene oxide solution in concentrated hydrochloric acid (8 M, 120 °C) under N 2 atmosphere. X-ray photoelectron spectroscopy analysis revealed that the Cl content was 1.01 at.% in the Cl-RGO. Electrochemical measurements indicated that the Cl-RGO modified glass carbon electrode showed enhanced electrochemical conductivity and electrocatalytic activity for the veterinary drug chloramphenicol (CAP) detection. Thus a highly selective electrochemical sensor for CAP was constructed based on Cl-RGO, and a linear relationship between current intensity and CAP concentration (2-35 μM) was obtained with a detection limit of 1 μM (S/N = 3). The sensor showed excellent reproducibility, storage stability and was successfully used for CAP detection in milk, calf plasma, water and pharmaceutical samples.

“…Optical methods are advantageous because they show a quick response, simple operation, and high sensitivity. Optical aptasensors involve aptamers as a biorecognition element along with various optical approaches as signal transduction element ( 17 ). Optical aptasensors can be classified based on their luminescence changes and light absorption as a result of interaction with different analytes.…”

Cancer is a life-threatening concern worldwide. Sensitive and early-stage diagnostics of different cancer types can make it possible for patients to get through the best available treatment options to combat this menace. Among several new detection methods, aptamer-based biosensors (aptasensors) have recently shown promising results in terms of sensitivity, identification, or detection of either cancerous cells or the associated biomarkers. In this mini-review, we have summarized the most recent (2016–2020) developments in different approaches belonging to optical aptasensor technologies being widely employed for their simple operation, sensitivity, and early cancer diagnostics. Finally, we shed some light on limitations, advantages, and current challenges of aptasensors in clinical diagnostics, and we elaborated on some future perspectives.

“…Fluorescence assays can be divided into two groups including labeled and labelfree assays. Labeled assays require at least one kind of fluorophores/chromophores and generally utilize fluorescence resonance energy transfer (FRET) to detect various analytes [41]. A variety of fluorophore donors and acceptors such as fluorescent proteins and non-protein organic fluorophores and fluorescent dyes can be employed as a part of FRET-based assay.…”
