Positive: Latent fingerprints are unique to each individual, making them valuable for forensic identification. They can be used as evidence in criminal investigations to link a suspect to a crime scene.
Negative: Latent fingerprints can be challenging to collect and preserve due to factors like surface contamination or poor print quality. They may also be prone to errors during processing and analysis, potentially leading to misidentification.

What Is A Latent Fingerprint?
Latent fingerprint examiners are people who look at fingerprints left on a crime scene. Also register, search, analyze, and identify fingerprints in the Automated Fingerprint Identification System (AFIS). They also record criminal history and provides expert witness testimonies in court. They view animated or hard copies of fingerprints and they also prepare the print for computer entry. They also enhance the fingerprint with the computer. They also have to prepare displays of the latent fingerprint for testimonies.
What are latent prints?
Latent prints are fingerprints that are made and left behind by the deposit of oils and/or perspiration and they are invisible to the naked eye. They can be identified by using various physical and chemical detection techniques.
What chemical is used to catch red handed?
Ninhydrin is a common chemical used to develop latent fingerprints by reacting with amino acids in the print residue to produce a purple or pink color. This chemical is often referred to as a way to "catch red-handed" since it can reveal fingerprints left at a crime scene.
What requires more energy the latent heat vaporisation of water or the latent fusion of ice?
The latent heat of vaporisation of water requires more energy. This is because on melting, the intermolecular bonds in water are only weakened whereas on boiling, the bonds are completely broken, which requires a larger amount of energy.
What chemical bond possess low latent heat of fusion?
Latent heat of fusion (or enthalpy of fusion) is a characteristic of a substance, rather than a chemical bond. If you mean enthalpy of reaction then the lowest absolute values are for the bonds in H2, F2, and Cl2 as gases, which are zero. One low (and negative) value is for cuprous sulphate. Please see the link.
What is the name for hidden fingerprints?
latent fingerprints
Types of fingerprints that are usually found at a crime scene?
LATENT fingerprints.
What is a sentence for the word latent?
The forensic scientist tested the crime scene for latent fingerprints.
Do unknown latent fingerprints get stored in databases to get compared to future known fingerprints?
Yes.
What type of fingerprint that cannot be seen with the naked eye?
Latent fingerprints are the types of fingerprints that aren't visible to the naked eye.
What does ninhydrin do to the fingerprints?
Ninhydrin reacts with amino acids present in the sweat from fingerprints, producing a purple or blue color. This allows for the visualization and development of latent fingerprints on surfaces.
How are imprints collected in a crime scene?
Imprints at a crime scene can be collected using various methods such as dusting for latent fingerprints, using chemical techniques to enhance the visibility of footwear impressions, or capturing tire tread impressions using casting materials. These imprints can provide valuable evidence to help identify individuals or vehicles involved in the crime.
How do you find latent fingerprints?
Latent fingerprints can be found using techniques such as dusting, powdering, cyanoacrylate fuming, and ninhydrin. These methods help reveal hidden prints on surfaces by making the ridges of the fingerprint visible for examination and comparison.
What does a latent print specialist do?
specializes in collecting fingerprints etc from a crime scene or a criminal.
What does latent figerprints mean?
There is a good chance that fingerprints are present, but they cannot, or have not been found.
What should you do after photographing a processed latent fingerprint?
The photograph of the latent print should be transmitted to a central office where it can processed by comparing it with existing known fingerprints in order to identify the person responsible for the latent prints
Can you get a fingerprint off money?
Yes, there are several chemicals that can be used to develop latent fingerprints on currency.
