Conventional cancer mono-therapeutic approaches including radiotherapy, surgery, and chemotherapy don't always achieve satisfactory outcomes and are frequently associated with significant limitations. Although chemotherapy is a vital intervention, its effectiveness is frequently inadequate and is associated with metastasis, multidrug resistance, off-target effect, and normal cells toxicity. Phototherapies are employed in cancer therapy, encompassing photo-dynamic and photo-thermal therapies which under favorable NIR laser light irradiation initiate the included photosensitizers and photo-thermal agents to generate ROS or thermal heat respectively for cancer cells destruction.

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.
