“…The study also validated other attractive merits of the CD-Tb 3+ nanoprobe sensor, such as good aqueous and photostability, broad operating pH range (3.5–10.5), good linearity over the nanomolar detection range, and insignificant interference from various interfering acids, metal cations, and anions. A comparable study performed by Rong et al [ 211 ] demonstrated the viability of fabricating a color test strip using functionalized manganese-doped CDs for DPA sensing. The Mn-CDs were functionalized with ethylenediamine tetraacetic acid disodium salt and europium (Eu 3+ ).…”

Over the past decade, carbon dots have ignited a burst of interest in many different fields, including nanomedicine, solar energy, optoelectronics, energy storage, and sensing applications, owing to their excellent photoluminescence properties and the easiness to modify their optical properties through doping and functionalization. In this review, the synthesis, structural and optical properties, as well as photoluminescence mechanisms of carbon dots are first reviewed and summarized. Then, we describe a series of designs for carbon dot-based sensors and the different sensing mechanisms associated with them. Thereafter, we elaborate on recent research advances on carbon dot-based sensors for the selective and sensitive detection of a wide range of analytes, including heavy metals, cations, anions, biomolecules, biomarkers, nitroaromatic explosives, pollutants, vitamins, and drugs. Lastly, we provide a concluding perspective on the overall status, challenges, and future directions for the use of carbon dots in real-life sensing.

The present review (containing 242 references) illustrates the importance and application of optical and electrochemical methods as well as their performance improvement using various methods for the detection of pathogenic bacteria. The application of advanced nanomaterials including hyper branched nanopolymers, carbon‐based materials and silver, gold and so on. nanoparticles for biosensing of pathogenic bacteria was also investigated. In addition, a summary of the applications of nanoparticle‐based electrochemical biosensors for the identification of pathogenic bacteria has been provided and their advantages, detriments and future development capabilities was argued. Therefore, the main focus in the present review is to investigate the role of nanomaterials in the development of biosensors for the detection of pathogenic bacteria. In addition, type of nanoparticles, analytes, methods of detection and injection, sensitivity, matrix and method of tagging are also argued in detail. As a result, we have collected electrochemical and optical biosensors designed to detect pathogenic bacteria, and argued outstanding features, research opportunities, potential and prospects for their development, according to recently published research articles.

“…Recently, promising optical biosensors were proposed as a tool for the determination of biological warfare agents using advanced nanotechnologies. The development of methods based on new materials can be seen in the work by Rong et al, who manufactured manganese-doped carbon dots with ethylene diamine and ethylenediamine tetraacetic acid with bound Eu III+ [57]. The modified carbon nanoparticles interacted with 2,6-dipicolonic acid, which is a biomarker of Bacillus anthracis spores, and the presence of 2,6-dipicolonic acid caused change of fluorescence from intense blue to bright red.…”

Biosensors are analytical devices combining a physical sensor with a part of biological origin providing sensitivity and selectivity toward analyte. Biological warfare agents are infectious microorganisms or toxins with the capability to harm or kill humans. They can be produced and spread by a military or misused by a terrorist group. For example, Bacillus anthracis, Francisella tularensis, Brucella sp., Yersinia pestis, staphylococcal enterotoxin B, botulinum toxin and orthopoxviruses are typical biological warfare agents. Biosensors for biological warfare agents serve as simple but reliable analytical tools for the both field and laboratory assay. There are examples of commercially available biosensors, but research and development of new types continue and their application in praxis can be expected in the future. This review summarizes the facts and role of biosensors in the biological warfare agents’ assay, and shows current commercially available devices and trends in research of the news. Survey of actual literature is provided.
