Special Issue Information

Dear Colleagues,

Recently, the field of nano-biosensors has grown rapidly. Nano-biosensors are being used for the detection of biomarkers related to the diagnosis of disease, and the application of nanomaterials in biosensing has influenced the biosensing field. The increase of surface area using nanomaterials has been important to high sensitivity and fast responsiveness. In the next decade, nano-biosensors will play an important role in diagnosis, image-guided therapy and development of personalized medicine. 

This Special Issue aims to introduce new smart nano-biosensors and their applications to improve cost-efficiency, sensitivity, and specificity of detection. We look forward to your participation in this Special Issue. We strongly encourage the submission of papers focusing on the topics described by the keywords below, but works on related topics will also be considered.

A biosensor is an integrated receptor-transducer device, which can convert a biological response into an electrical signal. The design and development of biosensors have taken a center stage for researchers or scientists in the recent decade owing to the wide range of biosensor applications, such as health care and disease diagnosis, environmental monitoring, water and food quality monitoring, and drug delivery. The main challenges involved in the biosensor progress are (i) the efficient capturing of biorecognition signals and the transformation of these signals into electrochemical, electrical, optical, gravimetric, or acoustic signals (transduction process), (ii) enhancing transducer performance i.e., increasing sensitivity, shorter response time, reproducibility, and low detection limits even to detect individual molecules, and (iii) miniaturization of the biosensing devices using micro-and nano-fabrication technologies. Those challenges can be met through the integration of sensing technology with nanomaterials, which range from zero- to three-dimensional, possessing a high surface-to-volume ratio, good conductivities, shock-bearing abilities, and color tunability. Nanomaterials (NMs) employed in the fabrication and nanobiosensors include nanoparticles (NPs) (high stability and high carrier capacity), nanowires (NWs) and nanorods (NRs) (capable of high detection sensitivity), carbon nanotubes (CNTs) (large surface area, high electrical and thermal conductivity), and quantum dots (QDs) (color tunability). Furthermore, these nanomaterials can themselves act as transduction elements. This review summarizes the evolution of biosensors, the types of biosensors based on their receptors, transducers, and modern approaches employed in biosensors using nanomaterials such as NPs (e.g., noble metal NPs and metal oxide NPs), NWs, NRs, CNTs, QDs, and dendrimers and their recent advancement in biosensing technology with the expansion of nanotechnology.
