A novel signal "on" type of photoelectrochemical biosensor for microRNA-21 hybridization detection was fabricated, where Bi2S3 nanorods were used as photoactive material with a maximum adsorption at 450 nm visible light, hairpin-structure DNA as detecting probe, streptavidin as signal capturing unit and biotin functionalized ascorbic acid loaded apoferritin as signal amplification unit. Hybridi...

Maize (Zea mays L.) is the most significant grain crop in South Africa. Despite its importance, cereal ravaged by several foliar fungal pathogens, which reduce maize quality and quantity at harvest. Hence, this study investigates fungi associated with diseases of Molelwane, North-West Province, The were isolated, characterized subjected to vitro nanoparticle control. Samples diseased leaves ase...

During the last decades, different sulphosalts were observed in several samples that investigated from Meleg hill, Velence Mts. The sample of this study was collected less studied north-eastern, stibnite-rich part hydrothermal breccia at Hill. Based on results electron microprobe analysis, we found contained two sulphosalt minerals andorite series have not been described Hungary before. is a su...

Non-invasive imaging modalities such as computed tomography are often used for diagnosis and assessment of gastrointestinal (GI) disease status over the long-term. The physiology of the GI tract can be assessed with contrast agents. Here, we present common protein (bovine serum albumin, BSA) stabilized bismuth sulfide nanoparticles with robust X-ray attenuation. Under the optimal conditions, th...

We report the proof-of-concept of molecularly imprinted polymer (MIP) functionalized Bi2S3/Ti3C2TX MXene nanocomposites for photoelectrochemical (PEC)/electrochemical (EC) dual-mode sensing chlorogenic acid (CGA). Specifically, in-situ growth served as a transducer substrate polymers such PEC and EC signal generators, due to its high surface area, suitable bandwidth abundant active sites. In ad...

Novel Bi(2)S(3)/BiOI heterostructures were successfully synthesized through a facile and economical ion exchange method between BiOI and thioacetamide (CH(3)CSNH(2)), and characterized by multiform techniques, such as XRD, Raman, FT-IR, XPS, SEM, TEM, HRTEM, SAED, BET and DRS. The obtained Bi(2)S(3)/BiOI photocatalysts showed excellent photocatalytic performance for decomposing organic dye meth...
