#1 [17.8] Synergistic MIP-aptamer dual-recognition on silver-decorated sulfur-doped graphene quantum dots (S-GQDs@Ag) nanohybrids for ultra-sensitive impedimetric carcinoembryonic antigen detection.

The clinical utility of Carcinoembryonic Antigen (CEA) as a cornerstone biomarker for oncological monitoring is frequently hindered by the limitations of traditional immunoassays, including high costs, specialized storage requirements, and complex procedural workflows. To address these challenges, we report the development of a high-performance ...

#2 [15.5] An ultrasensitive colorimetric platform for tetracycline based on the aptamer tailoring strategy and synergistic signal amplification of Au@Ce MOF.

In this study, a rapid Au@Ce MOF-Apt functionalized three-dimensional (3D) paper platform was constructed for the detection of TC in milk. To obtain a high-affinity aptamer (Apt), based on truncation and base mutation, resulting in high-affinity G-rich sequence aptamer (Apt-M24) (27 nt, -10.4 kcal/mol). Subsequently, the Apt-M24 was efficiently ...

#3 [15.5] A bioelectrochemical aptamer sensor using vanadium-porphyrinic metal-organic framework for noninvasive hydrocortisone monitoring in sweat.

Hydrocortisone (HC) is a vital steroid hormone secreted by the adrenal cortex that regulates how the body responds to stress, the immune system and metabolism. The primary objective of this study is the fabrication of an electrochemical aptamer sensor founded on a vanadium-porphyrin metal-organic framework (V-PMOF) to detect HC. V2CTx MXene acts...

#4 [15.3] Employment of mixed aptamers and gold nanobipyramids toward a paper-based aptasensor for simultaneously visual screening and accurate detection of eight sulfonamides.

A variety of sulfonamides (SAs) are extensively utilized in animal husbandry and aquaculture, necessitating the development of high-throughput methods for the rapid screening and accurate determination of multiple, ideally all commonly-applied SAs, in animal-derived foodstuffs. We herein developed a paper-based colorimetric aptasensor for the de...

#5 [13.8] Anchoring nanozymes on microneedles via nanotemplate sacrificial synthesis for glutathione detection.

Region-specific dysregulation of glutathione (GSH) reflects neuropsychiatric disorders and tumor progression. Microscale precision sampling combined with timely monitoring of GSH provides region-specific molecular information that may aid in disease diagnosis. To enable minimally invasive brain-compatible intraoperative detection of GSH within a...

#6 [13.7] Repurposing Type III CRISPR-Cas as Modular Cellular RNA Biosensors

Abstract Over the past decade, CRISPR-Cas based biosensors have emerged as sensitive, specific and programmable platforms for nucleic acid detection, with applications ranging from diagnostic tools, environmental monitoring and various applications in fundamental research. The vast majority of these biosensors are currently limited to in vitro a...

#7 [13.6] A cell surface-targeted MNAzyme-aptamer system for highly sensitive and visual detection of cancer cells via nucleolin activation.

Cancer has become a major disease that seriously threatens human health and life worldwide. Cytological diagnosis serves as a cornerstone for clinical oncology. However, conventional cytomorphological evaluation and immunohistochemistry (IHC) remain time-consuming and inadequate for large-scale screening and rapid on-site precision diagnosis. Co...

#8 [13.6] A self-powered photoelectrochemical aptasensor based on core-shell Z-scheme Co(3)O(4)@ZnO/ZnO@Co(3)O(4) heterojunction and bimetallic zeolitic imidazolate framework-derived templates for ultrasensitive detection chlorpyrifos.

Pesticide residues pose a serious threat to food safety and public health, making the development of rapid and sensitive on-site detection technologies a major challenge. Here a self-powered photoelectrochemical aptasensor is reported for ultrasensitive detection of chlorpyrifos in food samples. The sensor is based on a Z-scheme Co3O4@ZnO/ZnO@Co...

#9 [13.6] Single Au@Pt bimetallic nanoparticle collision electrochemistry: Deep learning-assisted prediction and ultrasensitive matrix metalloproteinase-9 sensing.

Single-particle collision electrochemical technology (SPCE) shows significant potential for nanoscale sensing, owing to its high spatiotemporal resolution and label-free characteristics. Nonetheless, its application in real biological samples faces challenges such as limited selectivity and complications in quantitative signal analysis due to co...

#10 [13.6] Triple quenching strategy-based highly sensitive electrochemiluminescence sensor for perfluorooctanoic acid.

Quenching-based electrochemiluminescence (ECL) sensing boasts prominent advantages for trace analysis, while single-mechanism systems have inherent flaws, making the development of efficient synergistic quenching strategies of great practical significance for ultra-trace perfluorooctanoic acid (PFOA) detection. In this work, a zinc-coordinated p...
