Exploring Carbon Dots: Green Nanomaterials for Unconventional Lasing

Small, Год журнала: 2024, Номер 20(47)

Опубликована: Авг. 20, 2024

In recent years, the progress toward lighting miniaturization is focused on luminescent nanomaterials. Among them, fluorescent carbon dots (CDs) are receiving increasing attention thanks to their astonishing optical properties complemented by intrinsic biocompatibility and low toxicity. The CDs can be easily dispersed in water, organic solvents or incorporated polymeric matrices, preserving emission properties. However, relationship between structural still not fully elucidated, motivating a consistent research effort for comprehension of features. Nevertheless, demonstrate efficient gain materials lasing, high quantum yield (QY), tunability visible near infrared (NIR) range, short lifetimes, absorption cross section, even if synthetic reproducibility, reaction spectral width may limit effective exploitation. This review summarizes latest advancements investigation characteristic that make laser action possible, illustrating geometries lasing random both solution solid state, few currently demonstrated breakthroughs. While journey application long, potential CD-based sources promising various technological fields futuristic perspectives will discussed.

Superoxide Dismutase-Mimetic Polyphenol-Based Carbon Dots for Multimodal Bioimaging and Treatment of Atopic Dermatitis

ACS Applied Materials & Interfaces, Год журнала: 2024, Номер 16(19), С. 24308 - 24320

Опубликована: Апрель 30, 2024

Polyphenols have been investigated for their potential to mitigate inflammation in the context of atopic dermatitis (AD). In this study, epigallocatechin-3-gallate (EGCG)-based carbon dots (EGCG@CDs) were developed enhance transdermal penetration, reduce inflammation, recapitulate superoxide dismutase (SOD) activity, and provide antimicrobial effects AD treatment. The water-soluble EGCG@CDs a few nanometers size exhibit negative zeta potential, making them suitable effective penetration. fluorescence properties, including an upconversion effect, make imaging probes both vitro vivo applications. By mimicking SOD enzyme, scavenge reactive oxygen species (ROS) actively produce hydrogen peroxide through highly catalytic capability toward reduction reaction, resulting inhibition bacterial growth. enhanced antioxidant high charge mobility, various functional groups prove reducing intracellular ROS model. mouse model, incorporated into hydrogel penetrated epidermal layer, leading scavenging, reduced mast cell activation, histological recovery skin barriers. This research represents versatile addressing advancing tissue engineering.

MedComm – Biomaterials and Applications, Год журнала: 2024, Номер 3(3)

Опубликована: Сен. 1, 2024

Abstract Carbon dots (CDs)‐based zero‐dimensional nanomaterials with dimensions ranging from 1 to 10 nm have shown tremendous potential in the application of regenerative medicine, because their unique physicochemical properties and favorable attributes like good biocompatibility, biological functions, low cost high stability. These newly synthesized CDs‐based could replace traditional semiconductor quantum dots, which obvious toxicity drawbacks higher costs. CDs not only show sustained fluorescent quality but also serve as superior carriers for drug delivery, well bioimaging‐guided detection cells, drugs, growth factors. So, they been play a role various fields such chemical sensing, bioimaging, photocatalysis. Thus, are considered candidates medicine applications. In this review, we provide comprehensive summary classification CDs, focusing on formation mechanisms, micro‐/nanostructures, distinctive properties. We describe synthesis methods detail. Furthermore, systematically highlight recent remarkable advances applications bone cartilage repair, wound healing, nerve regeneration, myocardial highlighted. Finally, discuss key challenges that lie ahead, outline future research directions, explore prospects materials medicine.
