Electrochemical biosensing using N-GQDs: Recent advances in analytical approach
2018
Abstract This review is meant to provide an overview of the electrochemical biosensors based on Nitrogen doped graphene quantum dots (N-GQDs) for analytical approaches, along with significant advances over the last several years in related technologies. In addition, this review described: i) Most frequently applied principles in biosensing based on of N-GQDs ii) The aspects of fabrication in the perspective of biosensing applications iii) The potential of various electrochemical, biosensors for the determination of target analytes within sub-micromolar range and the circumvention of the most serious problem in biosensing will be discussed. iv) Some of multiplex electrochemical biosensors ha…
RETRACTED: Optical bio(sensing) using nitrogen doped graphene quantum dots: Recent advances and future challenges
2018
Abstract The exceptional optical properties and the presence of high number of reactive sites make nitrogen doped graphene quantum dots (N-GQDs) powerful tools in analytical nanoscience and nanotechnology. At the same time, their opto-electronics properties make them excellent nanomaterials for biomedical analysis aspects. This review aims to explore progress to date various features of N-GQDs for optical bio (sensing) of target analytes. Moreover, as another aim of this review is to provide insight into the intensity based spectroscopic methods which are applied in bio (sensing) discussing their advantages and disadvantages. More importantly, we discuss in detail different aspects of the a…
