Colorometric Hydrogel based Nanosensor for Detection of Therapeutic Levels of Ionizing Radiation
Radiotherapy is a common medical procedure, especially for the treatment of cancers such as head and neck, breast prostate, lung and rectum. It is a complex process aimed at maximizing delivery of the planned dose to the tumor sites while minimizing unnecessary radiation to healthy tissues. Today, radiotherapy procedures make use of image guidance and...
