Nanoparticle-Enhanced Radiotherapy Techniques: Cellular Targeted Radiation Therapy with Nanoparticle-Mediated Radiosensitizing Drug Delivery to Tumours and GNRT
Abstract
For cancer patients, radiotherapy has proved a lifesaver. Innovations in the biological, engineering, and physical sciences gave rise to and advanced the subject. Continual incorporation of innovations from different domains is crucial to the advancement of radiation oncology. Nanomedicine is a very young scientific field with the potential to influence radiation oncology. Nanoscale materials are ideal for use in radiation oncology because to their numerous desirable characteristics, including improved permeability, retention effect, and superparamagnetism. Radiation therapy for cancer often falls short of expectations due to several limitations. Normal tissues are also at risk from radiation therapy, which is why it is not used as a focused anticancer treatment. Radiation treatment is often unsuccessful because tumours have characteristics that make them resistant. Because of their ability to interact directly with ionising radiation, a number of nanoparticles have demonstrated the potential to improve the feasibility of radiation treatment by increasing cellular radiation sensitivity. Nanoparticles made of metal, quantum dots, silica, polymeric materials, etc., have all been studied for their potential as radio-sensitizers, with the goal of increasing the effectiveness of radiation therapy and overcoming radio-resistance. The use of nanoparticles to improve and enhance radiation therapy for cancer treatment still faces significant obstacles, despite all the research and development in the field. Problems in guaranteeing large-scale production of nanoparticles with enhanced characterizations and specific biological obstacles limit their potential uses as radiosensitizers. Enhancing the treatment is possible by resolving the issues with nanoparticles, such as pharmacokinetics and physical/chemical characterisation. Further research into nanoparticles and their therapeutic effects could pave the way for the creation of radiation treatments based on nanotechnology that effectively combat a range of malignancies in the years to come.
