Phages as delivery vehicles and phage display.

Bacteriophages (Phages in short) were introduced as the natural enemy of bacteria that may act as alternatives to antibiotics to overcome the challenge of antibiotic resistance. However, in the recent history of science, phages have been employed in different molecular tools and used in numerous therapeutic and diagnostic approaches. Furthermore, thanks to the phage`s highly specific host range limited to prokaryotes, phage particles can be used as safe delivery vehicles and display systems. In this chapter, different phage display systems are introduced, in addition to various applications of phage display as a molecular and therapeutic tool in developing vaccines, antibacterial, and anti-cancer treatments.
