SYNTHESIS OF ARTICLE
An engineer at Drexel University came up with a hand held device that can determine if something is containing any sort of bacteria. Regular devices to determine if E Coli. Is present will take up to 24 hours; the device created at Drexel only takes 10 minutes. With this device, meat suppliers can send their products out a day earlier than before, allowing them to supply more product and make more profit at a time. The “ Drexel “ device allows quick and easy diagnosis, letting business move along with their shipment. Also giving humans faster results on if they were to have a bacterial infection.
This device could eventually put scientists out of their job, by no longer needed a human taking up to 48 hours or longer to analyze a certain bacteria.
Small sensor that detects bacteria
*Vocabulary *
Bioterrorism: Terrorism that relies on spreading diseases, such as anthrax and smallpox.
Imperative: something that demands attention or action; an unavoidable obligation
Spectrometer: an optical device for measuring wavelengths
Piezoresistance: describes the changing electrical resistance of a material due to applied mechanical stress
MEMS : is the technology of the very small, and merges at the nano-scale into nanoelectromechanical systems (NEMS)
NEMS: is used to describe devices integrating electrical and mechanical functionality on the nanoscale
SEI analysis
RELIABILITLY: the device that is used to detect bacteria is reliable because of its never ending battery, will allow the device to always be processing information, protecting people and could as well save business from law suits

Heyyyyyyy Girl! Im lovin it.
ReplyDeleteThis is a great resource to have.
Instead of waiting 24 hours to tell you if something is editable or not is a waste really when you could find out with this in just 10 minutes. That helps the business with the time and cost and lets the consumer get the meat sooner.
Your right with reliability because if a company purchases this sensor and it tells them false readings it could lose them meat if the sensor says meat is bad when its really not but also if it doesn’t detect if the meat does contain any bacteria which could cause people to become sick. If that was to happen to the company it could get tons of law suits from the people. So these people have to depend on these machines to tell them if the product is healthy enough to eat because lawsuits could cause many people to lose their jobs because of the budget cuts.
Also could part of the meat be contaminated, but the other half is tested would it still show that the meat is contaminated?

So, wait. This thing is inserted into meat? I don't understand how this device works. If it was to be implanted into the meat then what happens when someone eats the sensor? And how can it tell whether the E. Coli is really dangerous. There's definitely a difference between detecting E. Coli and detecting harmful E. Coli. And even if they do detect it before it gets shipped, how do they get rid of the bacteria? There are too many unanswered questions that come to mind when I read about things like this. However, it it pretty amazing that the sensor is so small! I keep forgetting that things keep getting more and more advanced as time goes on. This would definitely be helpful when it comes to the way our foods are being handled now-a-days. There have been far too many preventable contaminations in the food industry for my tastes, it would be very interesting to see these sensors come into play. Good work, Katelynn.
