This article is about an advance in technology that has helped us discover news way in removing and identifying fingerprints. Researcher Alex Goddard has discovered a natural technique to remove a fingerprint without disturbing the construction of it. The way that he does this involves studying the chemical and physical interactions occurring between the metal and the fingerprint sweat deposit. Using advanced surface imaging techniques, such as an atomic force microscope, observations of fingerprinted brass samples can identify optimum conditions to promote the natural enhancement of the fingerprint, vastly improving their recovery rate.
This article can help many crimes be solved. The way in which this article can help that is because of the major advance in technology presented in it. This technology will allow many crimes to be solved with even partial prints because it will be able to lift the print off of a bullet without destroying it.
In the world today this is extremely useful because now many of the murders that happen everyday will be solved and the people who break the law and harm others. In the world today this may help the crime rate in cities go down because criminals will start to think about the advancements in technology that might catch them for their crimes.

3. interesting topic
2. lots of detail
1. good explanation
2. maybe a little more about how the new technology works
1. more about the researcher
1. i learned that there are several ways of identifying fingerprints
3. Explaining the topic
2. Explaining the way they get the fingerprint.
1. excellent detail.
2. A lot more about the Dr.
1. How they get the fingerprint off the bullet.
1. that criminals might stop and think about there actions now.
The aspects of this review that were well presented were when he was describing how the technology works, how it can help solve crimes, and its potential impact on the future of forensic science.
This review could have been made better by explaining how previous methods of fingerprinting damaged the bullet, and how tested this new technology is.
I learned that less than 1% of fingerprints on bullets are recovered.
Three Aspects
1. Explanation of how this may help crime-scene investigators
2. Stating the researcher who discovered this technique
3. The reaction between metal and fingerprints.
Two Sugesstions
1. Explain how they lifted the fingerprints
2. Explain more about the chemical and physical reactions of metal and fingerprint sweat deposit
One Thing I've learned
1. Fingerprint evidence can be found on a bullet even after its been shot.
3. Explained what the scientists looked for to get fingerprints
2. How the new technology will deter criminals
1. Told who came up with the idea
2. Explain more about the new technology.
1. What does the atomic force microscope do.
1. I want to know what the atomic force microscope does.
There were many aspects of this review that were well presented. What I thought were most well presented was how the fingerprints can be uncovered using this new procedure and what machinery is utilized to do so. Another would be the affects this new technique will have on the criminal world and how it can lower crime rates. Third, is maybe the most important, that is that this new technique will greatly improve how forensic scientists uncover fingerprints and how it will help the future of crime investigations.
One way this review could be better is if it talked about how fingerprints used to be uncovered and how this new ways is drastically different and more advanced. Something like a compare and contrast of how the old way is different from the new and what similarities the new way has kept from the old way. It would also be better if it went more in depth about the chemical process of extracting the fingerprints from the bullets. I would like to know what chemical and physical reactions take place that make allow the fingerprints to be uncovered.
One thing I learned from reading this article was that, before this new technique was discovered, the previous discovery methods used powder to uncover the fingerprint. By doing this, the powder actually damages the print. I knew that powder was used to allow the fingerprints to be seen, but I did not know that the powder can damage the fingerprint. Overall I thought the article was very interesting.
1.Explanation of how this may help crime-scene investigators
2.Stating the researcher who discovered this technique
3.excellent detail.
1. talk more about how the technology works.
1. i learned all the different ways of identifying finger print
Three Aspects
1. Explanation of how the fingerprints can be uncovered using this new procedure
2. Stating the researcher who discovered this technique
3. How the new technology will deter criminals
Two Sugesstions
1. Explain how they lifted the fingerprints
2. Explain what the atomic force microscope does
One Thing I learned
I learned from the article that less than one percent of fingerprints on bullets are recovered.
Three Aspects:
-This article explains in depth how the technology works while making fingerprint removal from metals easier.
-It also explains how this new technology will be used in crime scene investigations.
-It also shows how previous methods could damage the evidence, and this new method promotes a naturally occurring process which is not damaging at all.
Two Suggestions:
-The article could have stated more information about how this new method was discovered, and information about the forensic scientist who discovered it.
-It also could have had more detail about how this method was used in crime scene investigations.
One Thing I've Learned:
-I learned that components of the sweat deposit survive washing and wiping of the surface.
3. Interesting and well explained topic
2. Good amount of description along with how things work to help solve crimes
2. This could have been better if there was more description on other ways to solve crimes
1. Explain more about the technology and how it works.
1. I learned that there are many different ways to find out who did what in a crime. Many different ways that criminals would not think of.
