Nanotubes, nanoparticles and antibodies detect tiny amounts of fentanyl

Nanotechnology News

02 May 2024

A research team at the University of Pittsburgh led by Alexander Star, a chemistry professor in the Kenneth P. Dietrich School of Arts and Sciences, has developed a fentanyl sensor that is six orders of magnitude more sensitive than any electrochemical sensor for the drug reported in the past five...

Physicists arrange atoms in close proximity, paving way for exploring exotic states of matter

Quantum Physics News

02 May 2024

Proximity is key for many quantum phenomena, as interactions between atoms are stronger when the particles are close. In many quantum simulators, scientists arrange atoms as close together as possible to explore exotic states of matter and build new quantum materials....

Nano-drugs hitching a ride on bacteria could help treat pancreatic cancer

Nanotechnology News

02 May 2024

Many pancreatic tumors are like malignant fortresses, surrounded by a dense matrix of collagen and other tissue that shields them from immune cells and immunotherapies that have been effective in treating other cancers. Employing bacteria to infiltrate that cancerous fortification and deliver these...

Twisting and binding matter waves with photons in a cavity

Quantum Physics News

02 May 2024

Precisely measuring the energy states of individual atoms has been a historical challenge for physicists due to atomic recoil. When an atom interacts with a photon, the atom "recoils" in the opposite direction, making it difficult to measure the position and momentum of the atom precisely. This...

Researcher creates optical magnetometer prototype that detects errors in MRI scans

Quantum Physics News

02 May 2024

Hvidovre Hospital has the world's first prototype of a sensor capable of detecting errors in MRI scans using laser light and gas. The new sensor, developed by a young researcher at the University of Copenhagen and Hvidovre Hospital, can thereby do what is impossible for current electrical...
