There is growing demand for the development of efficient ultrasensitive radiation detectors to
monitor the doses administered to individuals during therapeutic nuclear medicine which is
often based on radiopharmaceuticals, especially those involving beta emitters. Recently
biological materials are used in sensors in the nanobio disciplines due to their abilities to
detect specific target materials or sites. Artificially designed two-dimensional (2D) DNA
lattices grown on a substrate were analyzed after exposure to pure beta emitters, 90Sr-90Y …
