#1 [12.8] High-ThroughputOn-Chip Screening Enables Rapid Adaptationof DNA Aptamers to SARS-CoV-2 Evolution

Abstract Rapid pathogen evolution threatens public health by eroding the effectiveness of vaccines, therapeutics, and diagnostic tools. Although spike-protein-targeting monoclonal antibodies (mAbs) were developed within 10–12 months of the initial outbreak to serve as key theranostic agents, their redesign has struggled to keep pace with viral e...

#2 [12.1] Surface-confined CRISPR-Cas12a biosensor with metal-enhanced fluorescence for rapid and ultrasensitive detection of SARS-CoV-2 nucleocapsid protein.

CRISPR-Cas12a integrated with nanomaterials has formulated powerful biosensors for viral protein detection, addressing the urgent need for point-of-care diagnostics. However, existing platforms are hindered by either multi-step separation procedures or insufficient signal amplification, limiting their sensitivity and practicality. Here, we repor...

#3 [11.4] Single-Particle Tracking and Positional Phenotyping Reveal Variant-Specific Early Checkpoints in SARS-CoV-2 Cell Entry.

Bulk assays of SARS-CoV-2 entry obscure individual virions and conflate binding with internalization. We developed a quantitative single-particle imaging assay that classifies fluorescent virus-like particles (VLPs) as surface, crossing, or internal on HEK293T-ACE2 cells, separating binding from internalization. Comparing G614 and Omicron BA.5 S...

#4 [9.7] FOCUS: A Dual-Mismatch crRNA Strategy Unlocks High-Fidelity One-Step SNV Detection with Cas12a

CRISPR/Cas12a has emerged as a powerful tool for nucleic acid detection; however, its clinical utility is severely hampered by intrinsic limitations in single-nucleotide variant (SNV) discrimination, reliance on pre-processed single-stranded DNA (ssDNA) templates, and cumbersome multi-step workflows. Here, we report a novel molecular design prin...

#5 [9.7] Inhibitor-RegulatedCas12a Activation Enables HighlySensitive and One-Pot Detection of Drug-Resistant Genes in River Water

Abstract Monitoring environmental drug-resistance genes (DRGs) plays a pivotal role in preventing the transmission of antimicrobial resistance, thereby reducing public health risks. In this study, a one-pot recombinase polymerase amplification (RPA)/clustered regularly interspaced short palindromic repeat (CRISPR) assay was developed for monitor...

#6 [8.0] A label-free and highly sensitive fluorescence aptasensor for enrofloxacin detection based on G-triplex-mediated signal amplification.

Enrofloxacin (ENR), a third-generation fluoroquinolone veterinary antibiotic, is widely used in aquaculture and animal husbandry for bacterial infection control due to its broad-spectrum antimicrobial activity, potent bactericidal efficacy, and cost-effectiveness. However, its excessive and non-standard use has caused widespread residues in anim...

#7 [6.7] Threomer Inhibition of S1−ACE2 Binding

Abstract The interaction between the receptor binding domain (RBD) of the SARS-CoV-2 spike protein (S1) and human ACE2 receptor is essential for viral entry into host epithelial cells and a key target for drug discovery. Here, we describe the evolution of a threomer, a base-modified version of threose nucleic acid (TNA), that binds to the S1 pro...

#8 [6.3] Surface-Enhanced Raman Spectroscopy for Viral Diagnostics: Principles, Strategies, Clinical Challenges, and Future Directions.

Viral outbreaks such as SARS-CoV, MERS-CoV, and COVID-19 underscore the urgent need for rapid, sensitive, and scalable diagnostic technologies. Current standard methods, including nucleic acid amplification tests and immunoassays, offer complementary strengths but face limitations in cost, turnaround time, and early-stage detection. Surface-enha...
