Abstract G-quadruplexes (G4s) are non-classical DNA or RNA secondary structures that
have been first observed decades ago. Over the years, these four-stranded structural motifs …

Guanine-rich DNA sequences have the propensity to adopt four-stranded tetrahelical G-
quadruplex (G4) structures that are overrepresented in gene promoters. The structural …

Guanine-rich RNA sequences can fold into four-stranded structures, termed G-quadruplexes
(G4-RNAs), whose biological roles are poorly understood, and in vivo existence is debated …

Visualization of DNA and RNA quadruplex formation in human cells was demonstrated
recently with different quadruplex-specific antibodies. Despite the significant interest in these …

Guanine and related nucleobases such as guanosine, deoxyguanosine and isoguanosine
are notable molecular tools for designing functional supramolecular assemblies. This …

G-quadruplexes are non-canonical secondary structures found in guanine rich regions of
DNA and RNA. Reports have indicated the wide occurrence of RNA G-quadruplexes across …

A label free difunctional electrochemiluminescence (ECL) sensor for the ultrasensitive
detection of mercury ions (Hg 2+) and silver ions (Ag+) was constructed based on Ru (bpy) 3 …

G‐Quadruplexes are distinct nucleic acid secondary structures that are formed from G‐rich
DNA and RNA sequences; they are built around successive G‐tetrads of Hoogsteen …

In this work, based on mesoporous silica containers (MSNs) with the programmed enzyme-
free DNA assembly amplification of catalytic hairpin assembly (CHA) and hybridization chain …

Abstract G-quadruplexes (G4s), which are known to have important roles in regulation of key
biological processes in both normal and pathological cells, are the most actively studied non …
