Is there any kind of material that fingerprints can't be left behind on.?

Answer 1

Assuming that the question refers to solid materials, fingerprints are left behind on any solid material where oil can be transferred. Technically speaking, fingers will leave oil deposits in the form of a fingerprint on any solid material they touch.

However, it is one thing to leave a print, but something completely different for (1) that print to remain intact, and (2) someone to lift that print in a way that would allow it to be processed.

In order for the print to remain intact, the solid object must also stay intact. If a print were somehow left on ice, it would naturally not remain intact if the ice melts at all or if it breaks apart. Likewise, prints left on small objects like sand or soil particles will not remain intact if those particles move. The same goes for certain types of fabric, which can be a huge challenge because the fibers themselves may not always stay in the same place or configuration.

In order for the print to be able to be lifted in a way that makes it useful, there needs to be enough of a print for the system to be able to process it and compare it with other prints in a meaningful way. Therefore, extremely porous objects (some fabrics, certain types of masonry, etc.) can be challenging, since the ridges and holes on the surface can make print retrieval somewhat complicated. (It can still be done, though, depending on the nature of the object.) Once again, prints left on very small objects like sand and soil cannot easily be retrieved in a meaningful way, since the sand and soil the print is left behind on will be lifted right along with the print. (From a technical standpoint, this could still be done, but the process would be much more complicated than a standard print lifting.)

Answer 2

Liquid or gas, but if you are talking solid surfaces, nope. Because the ridges in your fingerprints hold oil, and are textured, almost anything will hold the print. And because of the oil, they will stay in tact for a very long time. That's one reason why fingerprints can be used to ID someone at crime scenes. Each persons are different, so they are almost as certain as DNA.

Answer 3

I had a peeping tom once. I asked the police to dust for fingerprints and they told me they wouldn't be able to get any from the aluminum siding.

Answer 4

Only a liquid.

The print will be left in the liquid and disappear after the finger is lifted.

(guess that goes for a gas as well...)

Answer 5

lets see......

1. water or any type of liquid
2. fiber...unless you leave behind some sort of dna which can be considered a "genetic finger print"
3. air and any form of gas.
4. fire...unless you want to get burned lol

Answer 6

Answer 9

i don't know probably cloth
