About this Research Topic
Organic–inorganic hybrid architectures are formed by hybridization of organic and inorganic components, and have at least one component on nanometer scale. These are rapidly emerging and highly promising materials owing to their interesting characteristics, such as thermal and chemical stability, mechanical strength, improved electrical, and optical properties, etc. All of these properties arise from the synergy created by the hybrid interface, rather than contribution from individual components. The level of synergy, however, depends on the type of interactions involved as well as surface energy. The inorganic component can facilitate enhanced mechanical, chemical, and thermal stability and provide an interconnected porous network. This is advantageous in a myriad of applications including sensing and catalysis, and can contribute to the magnetic, electrochemical, and chemical properties. The organic component can act as a matrix for reactions, help in the formation of thin films and fibers, facilitate various structures with controlled porosity and connecting networks, and can provide hydrophilic or hydrophobic properties depending upon the requirement. These hybrid materials have been studied for a number of applications such as electroanalytics, solar cells, semiconductors, catalysts, biosensors, drug delivery and more.
Food and water quality monitoring are global concerns, with policy makers putting vast effort into imposing stringent guidelines regarding this issue. In spite of these attempts, food and water quality is deteriorating every day due to uncontrolled use of chemicals to increase production, shelf life and appearance; or due to increased discharge of industrial waste water, resulting from fast growing industrialization, household waste, and a number of other unreported methods and processes.
Organic-inorganic hybrid nano-architectures can help in developing accurate, precise, and economical analytical methods attributed to the presence of rich functional groups, improved chemical and physical properties, and good regeneration ability. Although many nanohybrids have been reported, the main challenge that still remains is the green, sustainable and economic synthesis of these materials for the targeted applications. Moreover, precise control over assembly and shape is another of the biggest challenges faced by researchers. Relatively low use of highly catalytic and biocompatible nanohybrids for environmental applications is one of the research gaps that needs to be addressed when proposing future technologies using hybrid nanostructures.
