Опубликована: Янв. 10, 2025

Since their inception in the early 1960s, use of nanoscale materials has progressed leaps and bounds, role diverse fields ranging from human health to energy is undeniable. Nanosensors are devices having dimensions designed detect, record, transmit signals provide valuable data information. In this review, we utilize CAS Content Collection, a vast repository scientific information extracted journals patent publications, identify emerging applications field. This involves understanding trends, such as growth certain topics over time, well establishing relationships between topics. Our analysis indicates that among various nanomorphologies explored nanosensors, nanoparticles, nanotubes, quantum dots tend lead. terms types chemical biological sensors account for nearly 80% publications. combination with bibliographic data, utilized our access Registry identified host across substance classes (polymers, small molecules, elements) associated nanosensor Finally, major application nanosensors appears be biomedical nature (cancer diagnosis/testing drug discovery, example). findings highlighted TrendScape map provides an overview research interest concepts We also snapshot commercial development briefly discuss currently under development. It hope review comprehensive field serves guide researchers/scientists.

Liquid Water Molecular Connected Quantum Dots for Self‐Driven Photodetector

Advanced Functional Materials, Год журнала: 2025, Номер unknown

Опубликована: Янв. 17, 2025

Abstract The interactions between solid quantum dots (QDs) are weak as the excitons in QDs difficult to be dissolved into electrons and holes, which limits performance of based photodetector. Herein, through putting inside water, it is intriguingly found that holes by interaction water molecules, further contribute formation long‐range electron/hole transport channels within water. At zero voltage bias, a transient photo‐polarized current repeatedly produced, specific responsivity detectivity liquid‐based photodetector with molybdenum disulfide (MoS 2 ) aqueous suspension can reach 188.1 mA W −1 1.164 × 10 Jones 820 nm illumination, respectively. spectra photodetectors promoted selected different absorption peaks. Actually, cadmium selenide (CdSe) exhibits most significant enhancement effect at peak exciton wavelength QDs, much more holes. It anticipated ability dissolve form conducting dynamic construction molecules will bring possibilities for high‐performance optoelectronic devices across wide range application scenarios.

Endogenous Free-Electron-Involved Coreactant-Free Electrochemiluminescence from Nanoclusters and Its Immunoassay Application

Analytical Chemistry, Год журнала: 2025, Номер unknown

Опубликована: Фев. 21, 2025

All of the commercialized electrochemiluminescence (ECL) immunoassays are automatically conducted at +1.40 V (vs Ag/AgCl) in coreactant route. To alleviate exogenous effect coreactants and simplify operation procedures, herein, a sulfur-vacancy-involved free electron strategy is proposed to exploit Au nanoclusters (NCs) as anodic electrochemiluminophores perform coreactant-free immunoassay. The deficient coordination between sulfhydryl Met core might induce departure partial S atoms enable Met-capped AuNCs (Met-AuNCs) with electron-rich nature. nature tends endow Met-AuNCs unpaired endogenous electrons, which can directly combine holes for light emitting. Coreactant-free ECL around +0.86 consequently conveniently achieved by merely oxidizing anode. qualified determine human carcinoembryonic antigen from 10 5000 pg/mL limit detection 5 pg/mL. Electron paramagnetic resonance provides clear evidence that electrons within play an important role generation ECL. This promising designing nanoelectrochemiluminophores improved immunoassay performance.
