Lateral flow assays (LFAs) are currently the most used point-of-care sensors for both
diagnostic (eg, pregnancy test, COVID-19 monitoring) and environmental (eg, pesticides …

Serving as the basis of cell life, interactions between nucleic acids and proteins play
essential roles in fundamental cellular processes. Aptamers are unique single-stranded …

Aptamers are single-stranded nucleic acids that bind and recognize targets much like
antibodies. Recently, aptamers have garnered increased interest due to their unique …

The continuous, real-time measurement of specific molecules in situ in the body would
greatly improve our ability to understand, diagnose, and treat disease. The vast majority of …

Virus threatens life health seriously. The accurate early diagnosis of the virus is vital for
clinical control and treatment of virus infection. Aptamers are small single-stranded …

Conventional biosensors rely on the diffusion‐dominated transport of the target analyte to
the sensor surface. Consequently, they require an incubation step that may take several …

Many systems have been designed for the detection of SARS-CoV-2, which is the virus that
causes COVID-19. SARS-CoV-2 is readily transmitted, resulting in the rapid spread of …

Nucleic acids are remarkable molecules. In addition to Watson–Crick base pairing, the
different structural motifs of these molecules can bind non‐nucleic acid targets or catalyze …

Efficient and timely testing has taken center stage in the management, control, and
monitoring of the current COVID-19 pandemic. Simple, rapid, cost-effective diagnostics are …

The molecular biomarkers are molecules that are closely related to specific physiological
states. Numerous molecular biomarkers have been identified as targets for disease …
