7.1 Introduction

Nanoparticles (NPs) have drawn considerable interest due to their peculiar and interesting properties and applications that are beneficial over their bulk counterparts, with one or more dimensions on the order of 100 nm or less [1]. To synthesize various types of NPs, there are a large number of physical, chemical, biological, and hybrid methods available. While physical and chemical methods are more common in the synthesis of NPs, their biomedical applications, especially in clinical fields, are greatly restricted by the use of toxic chemicals. Therefore, to expand their biomedical applications, the development of reliable, nontoxic, and eco‐friendly methods for the synthesis of NPs is of utmost importance. One of the options is to use microorganisms to synthesize NPs to achieve this objective [2]. In several respects, NPs produced by a biogenic enzymatic process are far superior to those particles produced by chemical methods. Although the latter methods are capable of producing large amounts of NPs with a given size and shape in a relatively short period of time, they are complex, obsolete, expensive, and inefficient, producing hazardous toxic waste that is harmful not ...
