Abstract

Carbon dots represent a rapidly advancing and expanding research field, with a large number of literature reports on their potential technological applications including those relevant to food safety. In this article, the dot samples prepared by the deliberate chemical functionalization of preexisting small carbon nanoparticles or by thermal carbonization of various organic precursors under different processing conditions are highlighted and critiqued for their similarities and differences in sample structure-morphology and properties, especially antimicrobial properties for their food safety–related uses. Also highlighted and discussed are representative recent examples for the use of dot samples to inactivate foodborne pathogens, disrupt biofilms or prevent their formation, and extend the shelf life of food products, which involve different antibacterial mechanisms. Some perspectives on the further development of the carbon dots–based/derived antimicrobial platform and related excellent application opportunities in food safety are provided.

期刊介绍： The objective of the Journal of Nanoparticle Research is to disseminate knowledge of the physical, chemical and biological phenomena and processes in structures that have at least one lengthscale ranging from molecular to approximately 100 nm (or submicron in some situations), and exhibit improved and novel properties that are a direct result of their small size. Nanoparticle research is a key component of nanoscience, nanoengineering and nanotechnology. The focus of the Journal is on the specific concepts, properties, phenomena, and processes related to particles, tubes, layers, macromolecules, clusters and other finite structures of the nanoscale size range. Synthesis, assembly, transport, reactivity, and stability of such structures are considered. Development of in-situ and ex-situ instrumentation for characterization of nanoparticles and their interfaces should be based on new principles for probing properties and phenomena not well understood at the nanometer scale. Modeling and simulation may include atom-based quantum mechanics; molecular dynamics; single-particle, multi-body and continuum based models; fractals; other methods suitable for modeling particle synthesis, assembling and interaction processes. Realization and application of systems, structures and devices with novel functions obtained via precursor nanoparticles is emphasized. Approaches may include gas-, liquid-, solid-, and vacuum-based processes, size reduction, chemical- and bio-self assembly. Contributions include utilization of nanoparticle systems for enhancing a phenomenon or process and particle assembling into hierarchical structures, as well as formulation and the administration of drugs. Synergistic approaches originating from different disciplines and technologies, and interaction between the research providers and users in this field, are encouraged.
