In the realm of nanomaterials, atomically precise quasi-molecular gold nanoclusters (AuNCs) play a prime role due to their unique, stable, and highly tunable optical properties. They are extensively structure-engineered for modulation surface electronic states toward long wavelength photoluminescence, particularly in NIR-II (1000 1700 nm) window. Contrast agents with emission can potentially transform imaging terms higher spatial resolution, deeper tissue penetration, reduced autofluorescence. These advantages allow real-time living organisms observing disease progression treatment response. this short review, we discuss origin rationally designed AuNCs application high resolution vasculatures hard soft structures identification pathological conditions such as stroke injury. Further, recent employment these rapidly growing field tumor theranostics is also summarized. Final remarks provided on scope improvement properties persisting challenges clinical translation.

Copper ferrite nanoparticles for use as MRI contrast agents were synthesized using two different methods. A novel microwave-assisted (MW) solvothermal method was developed and compared to a conventional 12-hour synthesis (Reflux) an eco-friendlier approach. This innovative successfully produced with enhanced properties traditional materials. The nanoparticles’ morphological magnetic evaluated tested in in-vivo studies. results revealed both similarities differences between the amine-functionalized copper nanoparticles. FTIR, XRD, HRTEM, VSM analyses indicated improved CuFe 2 O 4 -NH MW particles, while AFM confirmed successful polymer encapsulation of For sample, 76.8 wt% 23.2 magnetite detected, crystallite sizes 8 ± nm 13 nm, respectively. In Refl. addition these phases, larger particles (31.6 wt%) also formed. DLS analysis demonstrated that sample exhibited excellent colloidal stability, maintaining its size distribution aqueous media 3 hours without aggregation, unlike which showed slight aggregation. displayed superparamagnetic behavior (Ms: 15 emu/g, Mr: 0 Hc: Oe), ferromagnetic characteristics 40 1.35 30 Oe).

Abstract Fluorescence signal “turn‐on” lateral flow immunoassay (FONLFA) through nanomaterial labeled quenching fluorescent has shown significant potential for the detection of small molecules. However, immobilization on nitrocellulose (NC) membrane commonly requires tedious chemical modification and only a few combinations fluorescence donor quencher have been applied in FONLFA. In this work, bright metal nanoclusters (Prot‐AuNCs) were prepared self‐assembled into Prot‐AuNCs/antigen aggregates with three typical molecule antigens, respectively. The can be readily immobilized surface NC membrane, indicating that strip fabrication strategy good versatility. Moreover, we evaluated performances FONLFA platform by using carbendazim as model target investigated four nanomaterials colorimetric nanoprobes quenchers. We found all demonstrated significantly improved naked eye sensitivity (vLOD) limits (LODs) quantitative analysis. Among them, combing Fe‐polydopamine nanoparticles above aggregates, mode achieved 200‐fold vLOD (0.05 ng mL −1 ) compared conventional AuNPs‐based (AuNPs‐LFA) (10 ). addition, LOD analysis also was 22‐fold whole test process completed within 10 min.
