Researchers at the University of Sheffield in the U.K have developed a gel that will glow under ultraviolet light. How does it work? The article says when the gel comes in contact with a bacteria such as E Coli, it attaches to it which changes the shape of the bacteria. This allows it to glow under the ultraviolet light. You're probably wondering why this is important, but the time savings of being able to detect such things quickly as opposed to sending it to the lab and waiting for results is certainly beneficial.
This is an emerging technology that should be explored but what comes to mind are the side effects. Will this gel do any harm to me in the long run? Sure it will detect the bacteria faster, but will it cause any issues such as accelerating the time it takes to spread to other areas of the body? I can see this being used in detecting viruses or could it just become a gel or spray that could do at home detection? Could this be used to see the amount of bacteria on produce before it is sent to stores for mass consumption? Would it be able to be used on furniture or machinery to detect bacteria before it spreads further? Maybe this would become a safety requirement?
In addition, what areas would it brush off into... it may become a safety requirement or standard in workplaces or by the CDC. If it is detected, what would consumers do? Would a whole line of cleaners or wipes be created to remove the bacteria? Or would a company need to come in and remove? This is a very interesting idea but I believe there are still a number of questions that need to be answered before consumers will trust using such a gel although the benefits could be life saving!
Yes, as crazy as it sounds this may be coming an airport near you! One potential use of this technology are airport screenings as well as checkpoints at border crossings and large venues. What if it detects you or I as a criminal when we most certainly are not one, nor are planning on committing a crime in the future. How would you go about arguing that? I know I would be more than upset if I went to the airport and was not allowed on a flight because the machine set off one of the alarms when I know it is false. If you were wrongly accused, would this affect your credit or security clearance? 
Have you ever been in a hospital and seen someone with tubes going every which way? If you haven't, you've surely seen someone either in person or on TV. What if one of those tubes could be eliminated by using wireless technology? Sounds crazy but those at the University of Utah in Salt Lake City successfully tested this theory by noticing variations in a wireless signal strength being triggered by a person breathing. They used 2.4 gigahertz radio waves across the hospital bed and were able to estimate a persons breathing rate up to 0.4 breaths per minute! 
This would allow patients added comfort and sounds appealing. The article mentions this only occurs at certain areas in a room. So if a patient were to move to area where this did not work and stopped breathing, would it go undetected and possible cause a death? Those at the University of South Florida argue that the benefit of the tubes is that it monitors the amount of carbon dioxide in exhaled gases, wireless monitoring would not allow for that. On the surface this technology sounds great but when you are talking life or death, not sure I would feel comfortable with the wireless technology.
