Gold nanostar colorimetric detection of fructosyl valine as a potential future point of care biosensor candidate for glycated haemoglobin detection
(MDPI, 2019)Diabetes Mellitus is a growing global concern. The current methods used to detect glycated haemoglobin are precise, however, utilise expensive equipment, reagents and consumables. These are luxuries which rural communities ... -
Modified HEPES one-pot synthetic strategy for gold nanostars
(RSC, 2019)Gold nanostars are being used more regularly in the biosensing field. Despite their useful attributes, there is still a need to optimize aspects of the synthesis and stability. The seedless, synthetic method comprising ... -
Plasmonic detection of glucose in serum based on biocatalytic shape-altering of gold nanostars
(MDPI, 2019)Nanoparticles have been used as signal transducers for optical readouts in biosensors. Optical approaches are cost-e ective with easy readout formats for clinical diagnosis. We present a glucose biosensor based on the ... -
Seedless gold nanostars with seed-like advantages for biosensing applications
(The Royal Society, 2019)Gold nanostars (AuNSs) are seen as promising building blocks for biosensors with potential for easy readouts based on naked-eye and ultraviolet–visible spectroscopy detection. We present a seedless synthesis strategy for ... -
Tailor-made gold nanostar colorimetric detection determined by morphology change and used as an indirect approach by using hydrogen peroxide to determine glucose concentration
(Elsevier, 2019)Gold nanostars are being utilized more regularly in the field of nanodiagnostics. The modified seedless synthetic method comprised of 4-(2-hydroxyethyl)-1-piperazineethanesulfonic acid (HEPES) synthesized with the ...
