Microhydration of the Guanine−Guanine and Guanine−Cytosine Base Pairs
The Journal of Physical Chemistry A, 2010Monohydration structures of the guanine-guanine and guanine-cytosine base pairs have been elucidated by IR-UV double resonance spectroscopy combined with ab initio calculations. The systems studied consist of the homodimer of 9-methylguanine and the heterodimer of 9-methylguanine and 1-methylcytosine in which the methyl group is introduced to mimic the

S-doped carbon dots capped ZnCdTe quantum dots for ratiometric fluorescence sensing of guanine
Sensors and Actuators B: Chemical, 2019Quantum dots (QDs)-based ratiometric fluorescence probe have drawn extensive attention in recent years. However, intrinsic dual-emitting QDs were rarely reported, and most of them were based on the metal doped-QDs.

Bioinspired Crystallization of Guanine
The Journal of Physical Chemistry Letters, 2021Biological guanine crystals in organisms exhibit excellent optical properties and functions, including broad-band and narrow-band reflectors, band-tunable reflectors, mirrors, and stimuli-responsive structural colors, attributed to the high refractive index of guanine (1.85) and the exquisite control of the polymorphs, morphologies, sizes, exposed ...

Conserved guanine-guanine stacking in tetraplex and duplex DNA
European Biophysics Journal, 2001Using a series of suitably chosen oligonucleotides, we demonstrate that the DNA duplex of d(CCCCGGGG) provides an almost identical CD spectrum as the parallel-stranded tetraplex of d(GGGG). The CD spectra are very sensitive to base stacking in DNA so that the above observation indicates that guanine-guanine stacking is essentially the same within the ...
