I meant to post this yesterday but I fell asleep. I had a 5 hour study session before my practical where we used different methods including wet powder (example shown) to identify fingerprints!

I was very nervous because I missed my last 2 practicals and thought I was too far behind but as it turns out I’m completely fine

Today I have a human anatomy practical that I need to study for as well, then I’m on break!

Fingerprint development methods are techniques used to enhance and visualize latent fingerprints, which are impressions left by the ridges of the fingers on surfaces. There are various methods for fingerprint development, including:

1. Powder Dusting: This method involves applying a fine powder, such as black powder or magnetic powder, to the surface containing the latent fingerprints. The powder adheres to the oils and moisture left behind by the fingers, making the prints visible.

2. Chemical Reagents: Chemical reagents are substances that react with the components of latent fingerprints, causing them to become visible. Examples include ninhydrin, which reacts with amino acids in the sweat, and cyanoacrylate fuming (Super Glue fuming), which creates a white polymer on the print.

3. Dye Stains: Dye stains involve applying a colored solution to the surface containing the latent fingerprints.

4. Physical Developers: Physical developers are solutions containing metallic salts that react with the components of latent fingerprints to form a visible deposit. Silver nitrate and zinc chloride are common examples of physical developers.

5. Laser and Alternative Light Sources: Laser and ALS, such as ultraviolet (UV) light or infrared (IR) light, can be used to visualize latent fingerprints that may not be visible to the naked eye. These sources can enhance contrast between the fingerprint and the surface, making them easier to detect.

6. Nanoparticle Techniques: Nanoparticle-based techniques involve using nanoparticles that specifically adhere to the components of latent fingerprints, making them visible under specific lighting or imaging conditions.

Each fingerprint development method has its advantages and limitations, and the choice of method depends on factors such as the surface type, the age of the prints, and the resources available in the forensic investigation.

Wanna play game? Here’s another piece of finger art inspired by popular characters I like.. now jigsaw might want to rip off your fingers until you learn your lesson but I just want to draw on them bc it’s fun and also I’m bored. 😂

The Merced Sun-Star, 24 February 1922

NEW YORK, Feb. 18. — Back yonder, when a famous scientist dumbfounded the world with his belief that man was descended from the monkey, there were those—and many there are now—who couldn’t see it that way. It may be interesting, then, to tell about Gabong’s finger prints. Gabong is an orang-utan, present habitat the Zoological Park in the Bronx. Now, Gabong hasn’t done anything criminal, but just the same his finger prints are on file in police headquarters. Furthermore, those police experts who have been on the finger printing job for years can’t tell at a glance the difference between the prints of Gabong and his alleged human brethren. Raymond Ditmars, curator of mammals and reptiles at the zoo, was anxious to get a real imprint of one of the orang-utan’s fingers. After trying successfully [I think they meant to write "unsuccessfully"] with vaseline and graphite, he called at headquarters, explaining the finger printing of monkeys wasn’t as easy as handling pickpockets and such. Monkeys squirmed too much. Sergeant William H. Hamersley, of the identification bureau thought the prisoners did a little squirming of their own and then explained how disobliging prisoners are caught off their guard. It isn’t necessary to ink their fingers. They touch a sheet of paper unthinkingly, which is then dusted with a powder that brings out the lines in complete detail. Mr. Ditmars returned to the zoo and tried it out on Gabong. The orang’s hands are as large as those of a man, and his thumb is similarly shaped. When the curator went again to headquarters with a print of Gabong’s thumb and one of his own and asked Sergeant Hamersley which of the two was the human print the expert couldn’t say. The sergeant referred the two prints to fourteen other experts in the identification bureau, none of them could say “this is Gabong,” or “this is Mr. Ditmars.” The police experts produced from the files a score of thumb prints with practically the same arrangement of whorls and ellipses that Gabong's thumb showed. A magnifying glass was necessary to find the difference in them.
