Band-gap-tunable carbon quantum dots for surface-enhanced Raman scattering

Research Square (Research Square), Год журнала: 2025, Номер unknown

Опубликована: Фев. 13, 2025

Carbon quantum dots (CQDs) with photoluminescence properties have been widely recognized, however, their inherent surface-enhanced Raman scattering (SERS) activity is rare reported. Herein, we propose a type of band-gap-tunable CQDs derived from metal-phenolic network (MPN) that exhibits excellent SERS performance. MPN-CQDs may be the ideal nonmetallic substrates to accurately elucidate chemical mechanism (CM) due simply controllable bandgap structure. By screening doped metal elements MPN, can realize optimal effect maximum enhancement factor 5.5×10⁴, also exhibit outstanding reproducibility and stability. We then systematically disclose interfacial photo-induced charge transfer process corresponding migration pathways between analyte. This class finally applied for detection hemoglobin high sensitivity; further combined machine learning algorithm, successfully achieved precise identification heterogeneity hemoglobin. first evidence tunable performance in CQDs, which offers facile avenue in-depth understanding CM materials.

A Semi-Interpenetrating Network Hydrogel with Excellent Photothermal Antibacterial and ROS Scavenging Activities for MRSA-Infected Wounds

ACS Applied Materials & Interfaces, Год журнала: 2025, Номер unknown

Опубликована: Март 2, 2025

The prolonged infection of bacteria at the wound site may lead to serious physical problems. Herein, a multifunctional macroporous hydrogel with superior photothermal antibacterial and ROS scavenging activity (denoted as M-XG gel) was designed for treatment MRSA-infected wounds. gels are composed embedding Prussian blue nanoparticles (PBNPs) converters chelating ferric ions xanthan gum (XG) dopamine (DA) form semipermeable network. introduction DA occupies cross-link sites ions, further increasing pore size (200-500 μm open macropores) endowing ideal adhesion. increase in PBNPs formed promising equilibrium gel identical structures toughened mechanical performance. metal ligands between catechols, well unique response PBNPs, endow hydrogels fast stable near-infrared (NIR) conversion efficiency (48%). In SD rat trauma model, wounds treated group had completely closed after 14 days, effectively controlling bacterial accelerating angiogenesis collagen deposition, synergistically promoting infected healing. Therefore, semi-interpenetrating network demonstrates its great potential tissue engineering.

Efficient Separation-Free and Wash-Free Immunoassay for Sensitive Detection of Biomarkers Based on the Distance-Driven Chemiluminescent Technique

Analytical Chemistry, Год журнала: 2025, Номер unknown

Опубликована: Март 19, 2025

The wash-free method represents a promising strategy for enhancing the detection efficiency of automated chemiluminescent (CL) immunoassay analyzers. Herein, novel separation-free and was developed first time based on distance-driven CL technique. In immunoassay, well-designed Au–Co metal nanoclusters (NCs) exhibited excellent peroxidase-like activity good stability, allowing efficient catalysis luminol or its analogue (ABEI)-H2O2 system even at low concentrations. Furthermore, large specific surface area NCs facilitated accommodation greater number antibodies, thereby capture antigens achieving dual amplification signal. technique relied formation sandwich-type immunocomplexes. Upon generation hydroxyl radicals superoxide anion through catalytic decomposition H2O2 by NCs, ABEI within immunocomplexes could efficiently react with these radicals, leading to significant enhancement in signals. C-reactive protein (CRP) chosen as model analyte evaluate practicability proposed immunoassay. Notably, presented high sensitivity, selectivity, reproducibility, successfully determining CRP serum samples recoveries 96.55–106.29%. Accordingly, advantage separation-free, wash-free, reliable characteristics drastically simplify operation steps enhance efficiency, which would make advances revolution traditional

Advances in Organic Porous Polymeric‐Supported Photothermal Phase Change Materials

Carbon Energy, Год журнала: 2025, Номер unknown

Опубликована: Апрель 1, 2025

ABSTRACT The urgent demand for renewable energy solutions, propelled by the global crisis and environmental concerns, has spurred creation of innovative materials solar thermal storage. Photothermal phase change (PTPCMs) represent a novel type composite material (PCM) aimed at improving storage efficiency incorporating photothermal into traditional PCMs encapsulating them within porous structures. Various encapsulation have been studied, including carbon, expanded graphite, ceramics, but issues like brittleness hinder their practical use. To overcome these limitations, flexible PTPCMs using organic polymers—like foams, hydrogels, wood—have emerged, offering high porosity lightweight characteristics. This review examines recent advancements in preparation based on polymer supports through techniques impregnation situ polymerization, assessing impact different PCM performance clarifying mechanisms conversion heat Subsequently, most applications polymer‐based are systematically summarized, future research challenges possible solutions discussed. aims to foster awareness about potential promoting environmentally friendly practices catalyzing further this promising field.
