The Cumberland County forensic lab's new Vacuum Metal Deposition can reveal latent fingerprints on materials, which used to be impossible to lift.

The machine deposits a thin layer of gold and zinc on the items under high-vacuum pressure. It can be used on paper money, plastic and fabric, and doesn't destroy DNA.

Glad you posted this is super cool. It also reminded me about something I meant to post the other day.

FBI Scientists Studying Wet Vacuum for DNA on Select Surfaces

The wet-vacuum method of collecting DNA from challenging surfaces, which has cracked a growing number of cold cases in some states, is being tested by scientists at the Federal Bureau of Investigation laboratory, according to a presentation two weeks ago at the Southern Association of Forensic Scientists annual meeting.

A whopping 47 times more DNA was pulled off the automotive carpet by the wet-vac system, as opposed to swabbing, according to the results. Twenty-eight times the genetic material was taken off the pine, seven times more was collected from the plywood, and five times more from the pressure-treated wood, according to a copy of the presentation.

I saw a demonstration of the wet vacuum system at CrimeCon last year. Very interesting technology.
