Determination of binding constants for the complexes between heavy metal ions and cucurbit[n]uril
Murray, Alenzo; Baker, Priscilla; Iwuoha, Emmanuel (John Wiley and Sons Inc, 2024)One of the major concerns worldwide is the rapid increase in water pollution with hazardous heavy metals. The Cucurbit[n]uril (CB[n]) structure provides an inner hydrophobic cavity accessible through two electrostatically ... -
Hall measurements on carbon nanotube paper modified with electroless deposited platinum
Petrik, Leslie; Ndungu, Patrick; Iwuoha, Emmanuel (Springer, 2010)Carbon nanotube paper, sometimes referred to as bucky paper, is a random arrangement of carbon nanotubes meshed into a single robust structure, which can be manipulated with relative ease. Multi-walled carbon nanotubes ... -
Influence of quantum dot surface on electrochemical DNA sensing mechanism
Fuku, Xolile; Baker, Priscilla; Iwuoha, Emmanuel (Wiley, 2020)Owing to their high surface‐to‐volume ratio, electrocatalytic activity, biocompatibility and novel electron transport properties, quantum dots (QDs) are highly attractive materials for the ultrasensitive detection of ... -
Quantum dot nanotoxicity investigations using human lung cells and toxor electrochemical enzyme assay methodology
O’Hara, Tony; Seddon, Brian; Iwuoha, Emmanuel (American Chemical Society, 2017)Recent studies have suggested that certain nanomaterials can interfere with optically based cytotoxicity assays resulting in underestimations of nanomaterial toxicity. As a result there has been growing interest in the ... -
Recent advances in the detection of interferon‑gamma as a TB biomarker
Januarie, Kaylin Cleo; Uhuo, Onyinyechi V.; Iwuoha, Emmanuel (Springer, 2021)Tuberculosis (TB) is one of the main infectious diseases worldwide and accounts for many deaths. It is caused by Mycobacterium tuberculosis usually afecting the lungs of patients. Early diagnosis and treatment are essential ... -
Spectroscopic and voltammetric analysis of platinum group metals in road dust and roadside soil
van der Horst, Charlton; Silwana, Bongiwe; Iwuoha, Emmanuel; Somerset, Vernon (MDPI, 2018)The emission of toxic compounds by increasing anthropogenic activities affects human health and the environment. Heavy road traffic and mining activities are the major anthropogenic activities contributing to the presence ... -
Voltammetric and spectroscopic determination of rare earth elements in fresh and surface water samples
Makombe, Martin; van der Horst, Charlton; Silwana, Bongiwe; Iwuoha, Emmanuel; Somerset, Vernon (MDPI, 2018)The increasing demand for rare earth elements in green technology, electronic components, petroleum refining, and agricultural activities has resulted in their scattering and accumulation in the environment. This study ...
