Carbon dots: Current advances in pathogenic bacteria monitoring and prospect applications

Optimization and characterization of eco‐friendly antimicrobial nanocellulose sheet prepared using carbon dots of white mulberry (Morus alba L.)

“…Among them, C-dots are particularly notable nanostructures with a strong antimicrobial potential as a result of a size of approximately 1-10 nm. 31 The synthesized C-dots from white mulberry revealed a good antimicrobial performance (21.27 mm ZOI) (Fig. 2) on L. monocytogenes, one of the most important foodborne pathogens.…”

Point-of-care diagnostics for infectious diseases: From methods to devices

“…The fluorescence signals are proportional to the target amounts. Except for traditional fluorescent dyes, some nanomaterials have also been widely employed for developing fluorescence biosensors due to their excellent fluorescence properties, such as quantum dots (QDs) [133] , carbon dots (CDs) [134] , [135] , upconversion nanoparticles (UCNPs) [136] , and metal nanoclusters (NCs) [137] , [138] , [139] , which have been widely applied for the fabrication of fluorescence biosensors. Herein, various direct fluorescence labeling biosensors for POC diagnostics of infectious diseases were summarized.…”

Superior Properties and Biomedical Applications of Microorganism-Derived Fluorescent Quantum Dots

“…Among the bacterial species that cause several bacterial diseases are Clostridium perfringens , E. coli O157:H7, Salmonella typhimurium , Listeria monocytogenes, Mycobacterium tuberculosis, S. aureus , Streptococcal sp., and Bacillus cereus [ 143 ]. Approximately 2.8 million in the United States of America are infected annually with resistant bacterial strains, which in turn causes almost 35,000 mortalities annually [ 144 ]. It is therefore becoming increasingly critical to address effective strategies for tracking and combating pathogenic bacteria in clinical settings, food, and the environment.…”

“…Generally, conventional plate counting and polymerase chain reaction (PCR) are two common methodologies used in bacterial detection and quantification. Although these methods are sensitive and precise, they require specific sample preparation and, as a result, they are time consuming [ 144 ]. Consequently, there is a crucial need to enhance the current methods for accelerated bacterial detection.…”

“…The presence of functional groups, such as sulfhydryl, amino, hydroxyl, and carboxyl groups on CDs greatly affects their antibacterial potential. This is because of CD charged surface, unique structure, and photocatalytic features which can be easily modified by different functional groups [ 144 ]. For instance, amines and amides of N -doped-CDs play a vital role in improving the antibacterial effects [ 149 ].…”
