AI Technical Summary

Benefits of technology

This invention relates to methods for detecting radioactive materials that use beta particles called ions (radiolabelled atoms). These techniques are used because they can be very sensitive but also have limitations such as requiring high levels of ionizing energy during detection processes. However, these technical means help improve their accuracy over other types of imagery without causing damage from excessive heat exposure.

Problems solved by technology

The technical problem addressed in this patented text is how to accurately identify harmful substances like radium (R) from environmental sources or weapons systems while minimizing costs associated with these activities. Current methods require extensive human effort and may lead to false alarms due to poor control on material containing them. Therefore, the goal is to develop better ways to quickly and efficiently measure both types of pollutions - specifically heavy metal particles called 141Cr which pose potential health hazards threatening military operations and civilian populations worldwide.

Embodiment Construction

[0084] The following detailed description is of the best currently contemplated modes of carrying out the invention. The description is not to be taken in a limiting sense, but is made merely for the purpose of illustrating the general principles of the invention, since the scope of the invention is best defined by the appended claims.

[0085] One aspect of the present invention is a method for detecting and / or determining a chemical species or analyte by using fibrous protein fibers. The chemical species or analyte to be detected can be in gas or liquid form. The chemical species can be inorganic or organic. For example, the chemical species can be a heavy metal such as strontium, cesium, lead, copper, cadmium, mercury, vanadium, radium, zinc, chromium, gold, silver, manganese, cobalt, nickel, or uranium. In another alternative, the chemical species can be a cyano or chloro complex of gold, silver, or platinum. Alternatively, the chemical species can be an organic species such as an

Abstract

Fibrous protein fibers such as keratin fibers can be used to detect chemicals and radiation. One aspect of the invention is a method of detecting an analyte in a sample comprising the steps of: (1) providing a fiber of fibrous protein; (2) contacting the fiber of fibrous protein with an sample that may contain an analyte; (3) measuring the conductivity of the fiber of fibrous protein in the absence of contact with the sample and in the presence of contact with the sample; and (4) correlating the conductivity of the fiber of fibrous protein in the presence of contact with the sample with the conductivity of the fiber of fibrous protein in the presence of contact with a reference sample containing a known concentration of analyte to detect or determine the analyte in the sample. Another aspect of the invention is a method of detecting radiation in a sample using a fibrous protein fiber functionalized with CdTe.
