It\u2019s not just something that\u2019s going to come off with soap,\u201d says Sweck, a double major in biochemistry and chemical engineering.<\/p>\n<p>The project is a collaboration between Gretchen Potts, UC Foundation professor of chemistry and faculty advisor on the project, and Chris Dockery, assistant chair in the Department of Chemistry and Biochemistry at Kennesaw State University in Atlanta. It began last year with UTC student Elizabeth Zuy, who ran tests to see if silicone bracelets could even be used in residue studies. Yes, they could.<\/p>\n<p>Potts says she has seen previous studies that tested silicone bracelets for organic chemicals encountered by roofers and thought the same might be possible with other chemicals.<\/p>\n<p>The current experiments are searching for seven organic compounds. \u201cWe\u2019re looking to be able to extract the residue from the wristbands and determine the difference in concentrations,\u201d Sweck says.<\/p>\n<p>The goal is for the information to eliminate \u201cfalse positives,\u201d Potts says. For instance, she explains, can the residue prove conclusively that someone set off firecrackers instead of welding or, yes, firing a gun?<\/p>\n<p>But lawyers and law enforcement shouldn\u2019t suddenly hope that the research can be used in cases that involve guns, warns Potts. That possibility is a long way off and may never materialize at all, she says.<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The silicone bracelet on your wrist might be more than just a statement of personal style.
