This technology is a colorimetric nano-sensor capable of detecting radiation doses such as those used in fractionated radiotherapy.
Currently, methods for measuring the dose of radiation delivered to a patient requires medical practitioners to use large dosimeters. These large dosimeters are complex to fabricate, expensive, and are often cumbersome to operate. With the limitations in current approaches and the frequency that radiation is used as treatment, there exists a need for radiation dosimeters that are both sensitive and convenient to use.
This technology is a dosimeter that utilizes nanomaterials to detect radiation. This sensor utilizes gold and silver nanomaterials that are applied to a colorimetric paper that, when exposed to radiation, experience a shift in their absorption spectra. This change can be imaged using traditional colorimeters to determine level and type of exposure. Colorimetry is a simple and cost-effective testing technique that does not require complex or bulky equipment and can deliver rapid results. By removing these hurdles, this assay can be readily applied to a variety of radiotherapeutic treatments and further expanded to test for environmental exposure to compounds such as radon in the home and workplace.
This technology has been validated for exposure to ionizing radiation levels of 0-30 Gy.
