Gold nanoparticulate modified thioglycolic acid (tga) phenotype nanobiosensor for tuberculosis drugs
(University of the Western Cape, 2022)Tuberculosis (TB) carries on being a major global health issue and it is responsible for 1.5 million disease-related mortality in 2020, according to the World Health organisation (WHO). One of the major causes of death ... -
Graphenated organic nanoparticles immunosensors for the detection of TB biomarkers
(University of the Western Cape, 2017)Pulmonary Tuberculosis (TB) a disease second to HIV/AIDS is a global health problem that arises in two states; as an active state and as a latent state. Diagnosis of active TB is tedious and requires expensive procedures ... -
Graphene based materials for carbon capture
(University of Western Cape, 2020)The adverse effects of CO2 and greenhouse gas emissions into the atmosphere is believed to be one of the causes of climate change. The seriousness of global warming is encouraging the development of technologies designed ... -
Graphene based nano-coatings: synthesis and physical-chemical investigations
(UWC, 2012)It is well known that a lead pencil is made of graphite, a naturally form of carbon, this is important but not very exciting. The exciting part is that graphite contains stacked layers of graphene and each and every layer ... -
Graphene modified Salen ligands for the electrochemical determination of heavy metal ions
(University of Western Cape, 2020)Environmental pollution is a major threat to all life, which needs to be addressed. Heavy metals are well-known environmental pollutants due to their toxicity and, persistence in the environment toxicity for living organisms ... -
