New microscope chemically identifies micron-sized particles

Researchers have developed a microscope that can chemically identify individual micron-sized particles. The new approach could one day be used in airports or other high-security venues as a highly sensitive and low-cost way ...

Graphene plasmons reach the infrared

Graphene's unique properties can be both a blessing and a curse to researchers, especially to those at the intersection of optical and electronic applications. These single-atom thick sheets feature highly mobile electrons ...

New sensor could help fight deadly bacterial infections

Scientists have built a new sensor that can detect the potentially deadly E.coli bacteria in 15-20 minutes, much faster than traditional lab tests. E.coli can be transmitted in contaminated food and water, posing particular ...

Scientists produce microresonators with unprecedented precision

Researchers from Aston University and ITMO University demonstrated a new method to fabricate optical microresonators with unprecedented precision of less than the diameter of a single hydrogen atom and 100 times less than ...
