What is chemical TSA?
Trichostatin A (TSA) is an organic compound that serves as an antifungal antibiotic and selectively inhibits the class I and II mammalian histone deacetylase (HDAC) families of enzymes, but not class III HDACs (i.e., sirtuins). TSA inhibits HDACs 1, 3, 4, 6 and 10 with IC50 values around 20 nM.
What is the stuff TSA wipe your hands with?
TSA officers swab your hands with a cotton cloth to collect explosives residue for testing in an Ion-Mobility Spectrometer (IMS), the machine they put the cloth in that determines if you go to your gate or to a private security screening.
How does TSA explosive detection work?
Officers may swab a piece of carry-on or checked baggage or a passenger’s hands and then place the swab inside the detection unit to analyze it for the presence of potential explosive residue.
What drugs do airport swabs detect?
Yet officials of Barringer have publicly stated their unit can detect TNT, RDX, PETN, Semtex, nitrates, NG, HMX and other chemicals in concentrations as small as 50 picograms (billionths of a gram).

How does Trichostatin a work?
Trichostatin A is a potent and reversible inhibitor of Histone Deacetylase (HDAC), therefore acting as an epigenetic modifier by preventing the removal of acetyl groups from lysine residues on histone tails.
Why does TSA scan your phone?
TSA said the screening “is solely intended to verify that there has been no physical tampering or hidden threat placed within the electronic device.”
Why did TSA swab my phone?
How are Bombs detected at airports?
The most commonly deployed explosives detection systems are walk-through metal detectors, AIT (or body scanners), multi-view X-ray machines used in conjunction with explosives trace detection (ETD) systems, and canine teams. Most air travelers in the developed world will be familiar with ETD systems.
