Controlled dehydration of a ruthenium complex-DNA crystal induces reversible DNA kinking
KELLY, JOHN (2014)Hydration-dependent DNA deformation has been known since Rosalind Franklin recognised that the relative humidity of the sample had to be maintained to observe a single conformation in DNA fibre diffraction. We now report ... -
The effect of the 4-amino functionality on the photophysical and DNA binding properties of alkyl-pyridinium derived 1,8-naphthalimides
GUNNLAUGSSON, THORFINNUR; KELLY, JOHN (2013)The synthesis and characterisation of two cationic pyridinium based 4-amino-1,8-naphthalimide derivatives (2 and 3) are described and compared to those of compound 1. The photophysical properties of 2 and 3 are shown to ... -
Long-lived excited states in i-motif DNA studied by picosecond time-resolved IR spectroscopy
KELLY, JOHN (2014)The transient IR absorption spectrum for UV-excited i-motif DNA is reported for the first time and found to possess complex dynamics pointing to multiple decay processes, including possible charge transfer between packed ... -
Microwave-assisted synthesis of ZnO micro-javelins
KELLY, JOHN (2009)The microwave (MW)-assisted formation of ZnO micro-javelins from zinc nitrate and urea in aqueous solution is described. The particles (named as `micro-javelins? because of their high aspect ratio and needle-like tips) ... -
Photophysical studies of CdTe quantum dots in the presence of a zinc cationic porphyrin
KELLY, JOHN; GOUNKO, IOURI (2012)The photophysical properties of 2.3 nm thioglycolic acid (TGA) coated CdTe quantum dots (QDs) prepared by a reflux method have been studied in the presence of cationic meso-tetrakis(4-Nmethylpyridyl) zinc porphyrin ... -
Ultrafast IR spectroscopy of polymeric cytosine nucleic acids reveal the long-lived species is due to a localised state
KELLY, JOHN (2012)The decay pathways of UV-excited cytosine polymers are investigated using picosecond time-resolved infrared spectroscopy. Similar yields of a non-emissive 1niU* state are found in the single-stranded dC30 polymer as in the ... -
Wash-free highly sensitive detection of C-reactive protein using gold derivatised triangular silver nanoplates
GOUNKO, IOURI; BLAU, WERNER; KELLY, JOHN (2014)A rapid, wash-free highly sensitive detection method for C-reactive protein (hs-CRP) is reported with both triangular silver nanoplate (TSNP) and Au-edge coated TSNP biosensor sols. The latter shows higher assay sensitivity ...
