Non-canonical nucleic acid structures possess an ability to interact selectively with proteins, thereby exerting influence over various intracellular processes. Numerous studies indicate that genomic G-quadruplexes and i-motifs are involved in the regulation of transcription. These structures are formed temporarily during the unwinding of the DNA double helix; and their direct determination is a rather difficult task.

- Rapid virus identification techniques are essential due to global epidemics, with existing methods like PCR being reliable but slow, and antibody-based strips being fast but less reliable.
- A new multiplex lithographic SERS aptasensor has been developed for quick detection of multiple respiratory viruses simultaneously, offering results in just 17 minutes.
- This sensor uses four labeled aptamers anchored on a metal surface, allowing for the simultaneous identification of viruses like SARS-CoV-2, influenza A, respiratory syncytial virus, and adenovirus through changes in SERS signals.
