Ten Minute COVID-19 Detection Test Using Nanoparticles

Scientists from the University of Maryland School of Medicine (UMSOM) developed an experimental diagnostic test for COVID-19 that can visually detect the presence of the virus in 10 minutes. It uses a simple assay containing plasmonic gold nanoparticles to detect a color change when the virus is present. The test does not require the use of any advanced laboratory techniques, such as those commonly used to amplify DNA, for analysis. Once a nasal swab or saliva sample is obtained from a patient, the RNA is extracted from the sample via a simple process that takes about 10 minutes. The test

That’s right, a Freddy Fazbear’s Pizza has mysteriously appeared in Hollywood. Like in the game and upcoming film, it’s a run-down spot that’s been closed down due to some mysterious activity within.

Check out the video captured by deadboifilms on TikTok below at the location on Sunset Blvd in Hollywood (near the Chateau Marmont Hotel). If you want to encounter the animatronic band of fuzzy and totally friendly creatures from the game, you’ll have to visit Universal Studios Hollywood Halloween Horror Nights, there’s a walk-through in the DreamWorks theater lobby that’s been taken over by Blumhouse which features the real Jim ...
