Approximately one-third of the world's food production, i.e., 1.43 billion tons, is wasted annually, resulting in economic losses nearly USD 940 and undermining system sustainability. This waste depletes resources, contributes to greenhouse gas emissions, negatively affects security prices. Although traditional packaging preserves quality, it cannot satisfy demands extended shelf life, safety, Consequently, active using biopolymer matrices containing antioxidants antimicrobials a promising solution. review examines current advancements integration carbon quantum dots (CQDs) into biopolymer-based packaging, focusing on their antioxidant antimicrobial properties. CQDs provide unique advantages over nanoparticles natural compounds, including high biocompatibility, tunable surface functionality, environmental explores mechanisms through which impart activities, synthesis methods, functionalization optimize efficacy matrices. Recent studies have highlighted that CQD-enhanced biopolymers maintain biodegradability with enhanced functions. Additionally, potential challenges, such as toxicity, regulatory considerations, scalability are discussed, offering insights future research directions industrial applications. demonstrates CQD-incorporated transform aligning sustainability goals advancing preservation technologies.

Sequential Detection of Hg²⁺ and TNT Using a Nitrogen‐Doped Polymeric Carbon Dots On–Off–On Fluorescence Sensor

Polymers for Advanced Technologies, Год журнала: 2024, Номер 35(10)

Опубликована: Окт. 1, 2024

ABSTRACT This work presents a fluorescence sensor based on nitrogen‐doped carbon dots (N‐CDs) utilized for sequential detection of Hg 2+ and TNT. The N‐CDs were produced by simple efficient hydrothermal process involving the combination black bean extract with citric acid (CA) ethylenediamine (EDA). resulting exhibit steady blue significant quantum yield 12%. We conducted thorough investigation into mechanism which NCDs is reduced in presence . Our analyses, included Stern–Volmer quenching tests, confirmed development stable complex between When NCDs‐Hg was exposed to TNT, selectively restored. “on–off–on” sensing capacity allows monitoring both demonstrating good sensitivity selectivity. has low limit (LOD) 3.1 46 nM ions TNT linear range 0–40 0–30 μM, respectively. study emphasizes potential application detecting heavy metals explosives at same time. It highlights their usefulness sophisticated environmental technologies that are suitable important applications.
