Preface

Over the last decades, nanotechnology gained the centre of attraction in all aspects of
modern science, and it has vital applications in the food chain, storage, quality
monitoring, processing, preservation, and packaging. The global population is
increasing rapidly; therefore, there is a requirement to produce food products in a
more proficient, non-toxic, and sustainable way. Food scientists and microbiologists
are interested in food safety and quality assurance to produce excellent-quality food
free of food pathogens. Nanotechnology plays a significant role in fulfilling the
desire of food microbiologists. In this context, scientists developed nanoemulsions,
nanohydrogel, nano-starch-based biofilms, biogenic metal nanoparticles, and nano-
antimicrobials for the eradication of harmful food pathogenic bacteria from a variety
of food products. Furthermore, microorganisms develop a strategical response
towards the existing antibiotic drugs by developing innate immunity which results in
evasion of the process of examination. Although antibiotics have become the
mainstay against the infection caused by microorganisms, however, the resistance of
microorganisms to these antibiotics is alarming on the rise. The resistance of
microorganisms against antibiotics results from the continuous use of antibiotics that
allow the pathogenic microorganism to transform their genotype, resulting in the
emergence of multidrug strains. The development of resistant strains emphasizes the
need to develop effective therapeutic options. Recently, scientists have begun
considering nanomaterials as an alternative to antibiotics due to their effective
biocidal and immunopotentiating properties. The number of nano-components in
conjugation with existing antibiotics, plant bioactive components, essential oils, and
biopolymers for bacterial infections result in lowering of uptake dosage and,
therefore, minimize the toxicity and reduce the probability of development of
resistance. The synergistic approach of nanomaterials with natural components may
serve as a complement to the existing therapies and may help control the serious
bacterial infections. Therefore, the present book is explaining nanotechnological
approaches towards the eradication of harmful effects of pathogenic microorganisms.
