This technology cannot, in any way, shape or form, be used for carry-on baggage. The technology involves making the substances (hair gels, etc) radioactive for a short period of time and then analyzing the decay spectrum.
20 years ago, in an earlier part of my career, I visited Westinghouse in PA. They had a prototype of this technology (known as neutron activation analysis) and it was already in beta testing at 3 airports at that time. The upside is there for checked baggage and cargo, but it is complicated and it takes people a bit smarter than the average TSA screener.
