Microbial Interactions at Nanobiotechnology Interfaces Molecular Mechanisms and Applications

This book covers a wide range of topics including synthesis of nanomaterials with specific size, shape, and properties, structure-function relationships, tailoring the surface of nanomaterials for improving the properties, interaction of nanomaterials with proteins/microorganism/eukaryotic cells, and applications in different sectors.

This book also provides a strong foundation for researchers who are interested to venture into developing functionalized nanomaterials for any biological applications in their research. Practical concepts such as modelling nanomaterials, and simulating the molecular interactions with biomolecules, transcriptomic or genomic approaches, advanced imaging techniques to investigate the functionalization of nanomaterials/interaction of nanomaterials with biomolecules and microorganisms are some of the chapters that offer significant benefits to the researchers.
