#1 [22.5] Bifunctional DNA multivalent structure integrating stable capture of urothelial carcinoma cells with CRISPR/Cas12a signal amplification for bladder cancer detection.

Noninvasive detection of bladder cancer remains challenging due to the limited analytical performance of current urine-based assays under realistic detection conditions. Here, we report a linear programmable DNA nanostructure that integrates multivalent aptamer recognition with CRISPR/Cas12a signal transduction for detecting tumor-derived urinar...

#2 [21.1] Shell-thickness-modulated electrochemiluminescence of colloidal quantum dots for ultrasensitive PSA detection.

Electrochemiluminescence (ECL) biosensors hold great promise for clinical diagnostics, yet their performance is often constrained by the limited efficiency and stability of available luminophores in complex biological matrices. Colloidal quantum dots (QDs) have emerged as attractive alternatives to conventional emitters, but a systematic underst...

#3 [18.8] Integrated single-tube detection of miRNAs in subpopulation-specific extracellular vesicles via spatially colocalized dual-module DNA scaffold.

Extracellular vesicles (EVs)-derived miRNAs are valuable non-invasive biomarkers for early cancer diagnosis. However, most current methods detect either total EVs-miRNAs or those from a single subpopulation, overlooking subpopulation heterogeneity. Moreover, EVs isolation and miRNA analysis are often conducted in separate workflows, increasing s...

#4 [18.1] Facile Siderophore Assembly Enables Bacterial Delivery of Nucleic Acid Therapeutics

Antibiotic resistance is an increasing threat to modern medicine that calls for the discovery of new antibiotics. RNA targeting is a promising approach for antibiotic development. In particular, antisense antibiotics, dubbed ASObiotics, are an exciting class of oligomers that show promise as powerful antibiotic agents. However, limited bacterial...

#5 [17.8] Steric hindrance effect synergizing hole-trapping technique: High-Stability and high-accuracy Si/CdS n-n heterojunction photoelectrochemical biosensing of amyloid-β42.

Due to rapid carrier recombination and photodegradation, cadmium sulfide (CdS), an n-type semiconductor photosensitive material, has a low utilization efficiency that restricts its use in biosensing. A synergistic hole-trapping approach utilizing steric hindrance effects is proposed in this paper. First, chemical bath deposition (CBD) is used to...

#6 [16.8] Readout of intrinsic and induced DNA shape by homeodomain transcription factor complexes.

Homeodomain transcription factors (TFs) recognize their DNA targets through both sequence-specific base contacts and readout of local DNA shape. Although intrinsic DNA structure is encoded by nucleotide sequence, it also undergoes protein-induced structural deformation upon binding. Yet, the interplay between intrinsic and protein-induced DNA sh...

#7 [15.5] Electropolymerized Aptasensor for Femtogram-Level Cytokine Detection.

Detecting cytokines at ultralow concentrations is important for the early diagnosis and monitoring of inflammatory and immune disorders, yet remains constrained by the sensitivity and stability of bioelectronic interfaces. Here, we present an electropolymerization strategy for preparing poly(amino-ʟ-tyrosine) (pALT) nanofilms as functional bioin...

#8 [15.4] PASTA: versatile tyramide-oligonucleotide amplification for multimodal spatial biology

#9 [15.3] A review of exosome isolation based on membrane protein recognition: Methods, performance, and challenges.

BACKGROUND: Exosomes participate in physiological and pathological processes such as intercellular communication, immune regulation, and tumor initiation and progression, holding significant potential in early disease diagnosis, therapeutic target identification, and drug delivery system development. However, the isolation of exosomes presents s...

#10 [14.3] Targeting Adaptive and Innate Immune Responses with Covalent Aptamers.

Covalent aptamers have recently found initial success as tools for fast and selective transfer of labels to target proteins. Here, aptamers targeting protein tyrosine kinase 7 (PTK7) and the mesenchymal-epithelial transition factor (cMet) were functionalized with electrophiles capable of covalently transferring small-molecule immune recruiters. ...
