#1 [20.2] High affinity and selective DNA aptamers for the detection of tobramycin in eye drops.

Tobramycin is a frontline aminoglycoside antibiotic with a narrow therapeutic window. Here, we report the selection of high-affinity DNA aptamers using a library-immobilization based SELEX strategy. The lead aptamer, TOB-2, binds tobramycin with a dissociation constant of 420 nM as determined by isothermal titration calorimetry, while exhibiting...

#2 [18.9] Magnetically induced aggregation-assisted mesoporous polydopamine/single-atom nanozyme platform for dual-channel detection and two-stage synergistic eradication of pathogens.

Contamination with foodborne pathogenic bacteria poses a severe threat to public health, necessitating the integration of detection with source sterilization technologies. Herein, we developed an integrated nanoplatform by combining an aptamer-modified mesoporous polydopamine/palladium single-atom carbon dot composite probe (MPDA/Pd SA@DA-CDs/Ap...

#3 [15.8] AI-driven Cu/Mn-CeO(2) nanozyme-functionalized paper-based biosensor for quantitative monitoring of alternariol in food.

The lack of rapid, user-friendly methods for alternariol (AOH), a prevalent emerging mycotoxin, presents a considerable analytical challenge. This work introduces an integrated sensing strategy advancing from classical homogeneous liquid-phase detection to a portable AI-enhanced paper-based biosensor. The system employed a Cu/Mn-CeO2 nanozyme as...

#4 [15.8] Microscale thermophoresis sensor for homogeneous and one-step protein detection based on dual aptamers binding induced DNA switch.

Rapid and sensitive detection of proteins is in great demand in disease diagnostics, drug discovery, basic research, and other biomedical applications. The emerging microscale thermophoresis (MST) technique, which enables to monitor fluorescence responses of fluorescent molecules under heating in real time, provides an attractive avenue for sens...

#5 [15.8] Multiplexed biosensing: A review of surface plasmon resonance platforms for biomarker analysis.

Surface plasmon resonance (SPR) has emerged as an important optical technology for the real-time, label-free analysis of biomolecular interactions. While its utility in detecting single analytes is well-established, the growing complexity of disease diagnostics demands tools capable of simultaneous multi-analyte detection. Many complex diseases,...

#6 [14.7] A Fentanyl-Responsive Microneedle Patch for Harm Reduction.

The efficacy of current opioid overdose interventions is fundamentally limited by their reliance on bystander detection and administration, leaving unwitnessed overdoses, a predominant cause of fatalities, unaddressed. Herein, we developed an innovative fentanyl-responsive microneedle (MN) patch (iNal patch) engineered as an autonomous harm redu...

#7 [14.1] Membrane-anchored DNA nanodevice with allosteric aptamer arms enables parallel probing and on-site drug delivery.

DNA-based molecular computation enables targeting of cells via multiple surface receptors. However, existing platforms are often limited to single-receptor detection per operation or rely on freely diffusing components, a common source of off-target interference. Here we show an intelligent DNA nanodevice (DND) that integrates multivalent recogn...

#8 [13.5] A Droplet-Microarray Platform for Multiplex Profiling of Breast Cancer Exosome Subtypes in Patients' Blood Plasma Samples.

Breast cancer is highly heterogeneous, with distinct subtypes-luminal A, HER2-positive, and triple-negative-each exhibiting unique behaviors and treatment responses. Accurate identification of these subtypes is essential for guiding personalized therapies and improving outcomes. Exosomes, small extracellular vesicles secreted by tumor cells, hav...

#9 [13.3] Dual Marker Co-Expressed Exosome-Based Liquid Biopsy Electrochemical Assay for Enhanced-Accuracy Diagnosis of Prostate Cancer.

Tumor-derived exosomes (TDEs) have emerged as clinically significant liquid biopsies for noninvasive early cancer diagnosis. Although serum prostate-specific antigens (PSA) are widely used for prostate cancer (PCa) screening, their diagnostic accuracy is compromised by elevated levels in nonmalignant conditions. B7H3, a protein overexpressed on ...

#10 [13.3] Defect-Engineered Fe-B MOFs with Intrinsic Neutral-pH Recognition for Accelerated Dual-Mode Detection of Staphylococcus aureus.

This study addresses the challenge of achieving sensitive and reliable Staphylococcus aureus detection in neutral-pH food matrices, where conventional boronate affinity ligands typically lose their binding efficiency. We developed a dual-mode colorimetric-electrochemical aptasensor by rationally designing a defect-engineered iron-boronic acid me...
