Most of the aforementioned procedures employ an oxygen-free atmosphere and heavy molecular weight polymers as protecting agent to prevent oxidation and aggregation of Cu NPs. The sensor systems were also test for real blood glucose sample where excellent performances suggested their analytical capability.
In this research, zeta potential of shape-controlled TiO2 nanoparticles synthesized from Ti OBu 4 and TiCl4 was studied comprehensively. Such materials have demonstrated potential capabilities in areas such as optics and electrochemical sensors.
O dye that would allow understanding the shape dependency of the heterogeneous catalysis. The sensor system relied on the catalytic properties of Porous Co3O4 NWs, which were fabricated via interconnected nanorods leading to formation of 3D porous morphology.
For each shape-controlled nanoparticle, there is a specified zeta potential curve and IEP. The major aims and objectives of this thesis can be divided three categories. In contrast silver, although less stable demonstrates higher molar extension coefficient compared to gold nanoparticles. Besides this the associated functionality is also known to play an important role.
The release of such chemicals in aquatic system is of environmental concern due to their carcinogenic, persistent and recalcitrant nature He et al. Among these materials, nickel oxide NiO has been widely used for the different applications in addition to the non-enzymatic glucose sensors M.
Besides these growth techniques, hydrothermal method is very well known and suitable at large scale because of its several advantageous features such as low temperature, cost effectiveness, simplicity and high product yield. However, the choice of which template to use depends on the growth directing and controlling potential of the selected template.
The overall zeta potential of shape controlled nanoparticles decreases as the pH increased. Among such processes, reductive degradation of toxic pollutant catalysed by metal nanoparticles is a convenient degradation model. The constant global rise in genetically engineered crops has led to an overall increase in the usage of pesticides Benbrook, In a study, the simultaneous usage of ethylene glycol as both the solvent and reducing agent for dodecylamine DDA and polyvinyl pyrrolidone PVP protected nickel nanoparticles has been studied D.
In addition to which, extensive work has been carried out showing that many organic contaminants can be mineralized into carbon dioxide and water on UV irradiated TiO2 nanoparticle suspension . Cao, synthesized copper nanorods in high yield using a composite template of polyethylene glycol PEG and cetyltrimethylammonium bromide CTAB.
Zeta potential became more negative when SDS concentration increased. To surmount such drawbacks, considerable interest is being paid in the development of non-enzymatic glucose sensors A.
Different nanostructures of NiO have been used in the design of non-enzymatic glucose sensors. Zeta potential became stable when SDS solution reached 1.
M Abdel Hameed, utilized nickel nanoparticles deposited over carbon Vulcan XCR for development of sensitive enzyme less sensor. Metal nanoparticles particularly, gold Ausilver Ag and copper Cu have drawn tremendous attention over other metals due to their most unique and fascinating property known as Localized Surface Plasmon Resonance LSPR.
In previous work, our group fabricated stable nickel nanoparticles using L-threonine Kalwar et al. Today, the trend towards the fabrication and engineering of non-enzymatic glucose sensors is highly increased due to their over edge advantages compared to the enzymatic based glucose biosensors Si et al.
IEP of the nanoparticles increased from 4. The composite material showed excellent capability towards oxidation of glucose with a sensitivity of Smoluchowski equation was chosen to calculate the zeta potential of TiO2 nanoparticles under the action of an electric field.
Interestingly some of the properties of special shaped copper nanoparticles are much greater than bulk copper, thus synthesis of special shaped copper nanoparticles is much focused. In comparison, colorimetric based methods can provide rapid naked eye detection, appropriate on site assessment capability, real time analysis of target metal ion due to simple configuration and portability to be used on site A.
Similarly Bothra et al. Textile industry and its wastewater have been increasing proportionally, making it one of the main sources of severe water pollution worldwide K. This shape dependent catalytic efficiency was further evaluated from activation energy EA of reductive degradation reaction.
