G-quadruplex based biosensor: A potential tool for SARS-CoV-2 detection

Xi, Hui ; Juhas, Mario ; Zhang, Yang

In: Biosensors and Bioelectronics, 2020, vol. 167, p. 112494

G-quadruplex is a non-canonical nucleic acid structure formed by the folding of guanine rich DNA or RNA. The conformation and function of G-quadruplex are determined by a number of factors, including the number and polarity of nucleotide strands, the type of cations and the binding targets. Recent studies led to the discovery of additional advantageous attributes of G-quadruplex with the...

A simple reaction for dna sensing and chemical delivery

Janett, Elia ; Diep, Kim-Long ; Fromm, Katharina M. ; Bochet, Christian G.

In: ACS Sensors, 2020, vol. 5, no. 8, p. 2338–2343

Reactions templated by nucleic acids are currently at the heart of applications in biosensing and drug release. The number of chemical reactions selectively occurring only in the presence of the template, in aqueous solutions, and at room temperature and able to release a chemical moiety is still very limited. Here, we report the use of the p-nitrophenyl carbonate (NPC) as a new reactive...

Optical and theoretical study of strand recognition by nucleic acid probes

Domljanovic, Ivana ; Taskova, Maria ; Miranda, Pâmella ; Weber, Gerald ; Astakhova, Kira

In: Communications Chemistry, 2020, vol. 3, no. 1, p. 111

Detection of nucleic acids is crucial to the study of their basic properties and consequently to applying this knowledge to the determination of pathologies such as cancer. In this work, our goal is to determine new trends for creating diagnostic tools for cancer driver mutations. Herein, we study a library of natural and modified oligonucleotide duplexes by a combination of optical and...
