Abstract While existing polyoxometalates (POMs) are predominantly utilized in a range of energy devices, their potential bioelectronics and optoelectronics, particularly organic photoelectrochemical transistors (OPECTs), remains unexplored. Here, the POMs this aspect is unveiled by POM/sulfide‐gated OPECT. The representative PW 12 /ZnIn 2 S 4 with cascading light‐harvesting enzyme‐like functionality enables unique on‐off OPECT operation. incorporation facilitates separation photogenerated charge carriers across heterojunction interface, consequently inducing pronounced gating effect. Linking CRISPR/Cas13a system correlating target miRNA‐21 biological generation H O , will enable polymerization dopamine into polydopamine thus sensitively inhibit gating. Experimental results demonstrated that developed sensor achieved good analytical performance detection limit as low 3.9 f m . This study demonstrates Given large family multifunction POMs, its implications diverse optoelectronics expected.

Abstract Solid‐state nanochannel biosensors are extensively utilized for microRNA (miRNA) detection owing to their high sensitivity and rapid response. However, conventional face limitations in fixed dynamic range, restricting versatility efficacy. Herein, we introduce tunable triblock DNA probes with varying affinities target miRNA engineer solid‐state capable of customizable range adjustment. The architecture comprises a poly‐adenine (polyA) block adjustable surface density anchoring, alongside stem loop blocks modulating structural stability. Through systematic manipulation these blocks, demonstrate the ability achieve diverse binding limits, achieving an initial 81‐fold range. By combining various affinities, extend this significantly 10,900‐fold. Furthermore, by implementing sequestration mechanism, effective biosensor is narrowed only 3‐fold span concentrations. advanced makes them highly promising broad spectrum biomedical clinical applications.

Sensitive and direct detection of circulating microRNAs (miRNAs) in undiluted human serums can significantly facilitate the diagnosis different diseases early stages; however, achievement such a goal is highly challenged by extremely complex sample matrix nature serums. Here, we show that sensitive rapid let-7a miRNA biomarker cancer patient be realized new size-permeable microcapsule bioreactor. The Cas13a/crRNA-dsDNA@polyethylene glycol core/shell biomicrocapsules are synthesized simple encapsulation etching steps. Such exhibit high stability, enhanced protein antifouling capability, size-selective permeability only allows short sequences to enter core cavities, thereby enabling down 0.21 pM within 20 min via signal amplification Cas13a/crRNA near-infrared (NIR) fluorescence signals. biomicrocapsule also unambiguous discrimination clear cell renal carcinoma patients from healthy groups serum samples, highlighting its robust clinical potential for disease diagnoses.

Early cancer detection is crucial for improving patient survival rates. However, current single-biomarker methods often face challenges, such as insufficient sensitivity, poor accuracy, and false positives. To address these issues, we report a dual-functionalized glass micropipet sensor (DFMS) capable of simultaneously detecting two biomarkers, nucleic acids proteins. The inner surface the functionalized with amino-modified silicon nanowires (SiNWs) to capture disease-related miRNAs, enabling ionic-current-based detection, while outer decorated gold nanoparticles anchor specific protein aptamers Raman-based detection. This dual-functionalization significantly enhances sensitivity selectivity by combining ionic amplification plasmonic Raman signal enhancement. achieves limits 1 aM miRNAs 0.001 ng/mL proteins, minimal mutual interference between modes, ensuring accurate independent Validation prostate biomarkers miRNA-1246 PSA, well gastric miRNA-106a CD44, demonstrates its outstanding selectivity, stability, broad applicability, providing novel approach early significant clinical implications.

Clustered regularly interspaced short palindromic repeats (CRISPR) and CRISPR-associated (Cas) protein systems are renowned for their high sensitivity specificity, enabling them as a powerful diagnostic toolbox. Multiplexed detection of panels targets, opposed to single is imperative reliable conclusive disease diagnostics. However, multiplex application the CRISPR/Cas system has long been hindered by indistinguishable signals from specific targets due nonspecific chaotic trans-cleavage. To make breakthrough, substantial efforts have devoted CRISPR/Cas-powered multiplexed biosensing strategies, which consequently experienced rapid development over past five years. This review systematically summarizes recent advances in encompassing Cas9, Cas12, Cas13. Key focus issues include strategies respective advantages limitations, sensing mechanisms, performance novel validated examples. Finally, status challenges critically discussed, future outlooks proposed potential practical application. Perspective aims inspire significant research promote next generation biosensing.
