Quick COVID breathalyzer could allow mass screening in public places | 21st Century Innovative Technologies and Developments as also discoveries, curiosity ( insolite)... | Scoop.it

Gust MEES's insight:

Quick COVID breathalyzer could allow mass screening in public places
(Nanowerk News) According to experts, bringing an end to the pandemic will require rapid screening of people attending large gatherings, such as conferences and weddings. Even those who are asymptomatic can still transmit COVID-19 to others, making it important to identify and isolate them until they are no longer contagious.
Now, researchers reporting in ACS Nano ("Noninvasive and Point-of-Care Surface-Enhanced Raman Scattering (SERS)-Based Breathalyzer for Mass Screening of Coronavirus Disease 2019 (COVID-19) under 5 min") have developed a prototype “breathalyzer” that can sensitively and accurately diagnose COVID-19, even in asymptomatic individuals, in less than 5 minutes.

Nanorobotic agents open the blood-brain barrier, offering hope for new brain treatments | 21st Century Innovative Technologies and Developments as also discoveries, curiosity ( insolite)... | Scoop.it

From www.nanowerk.com - March 25, 2015 12:05 PM

Gust MEES's insight:

(Nanowerk News) Magnetic nanoparticles can open the blood-brain barrier and deliver molecules directly to the brain, say researchers from the University of Montreal, Polytechnique Montréal, and CHU Sainte-Justine ("Remote control of the permeability of the blood–brain barrier by magnetic heating of nanoparticles: A proof of concept for brain drug delivery"). This barrier runs inside almost all vessels in the brain and protects it from elements circulating in the blood that may be toxic to the brain.

The research is important as currently 98% of therapeutic molecules are also unable to cross the blood-brain barrier.
“The barrier is temporary opened at a desired location for approximately 2 hours by a small elevation of the temperature generated by the nanoparticles when exposed to a radio-frequency field,” explained first author and co-inventor Seyed Nasrollah Tabatabaei. “Our tests revealed that this technique is not associated with any inflammation of the brain.

New nanotechnology method sneaks drugs into cancer cells before triggering release | 21st Century Innovative Technologies and Developments as also discoveries, curiosity ( insolite)... | Scoop.it

From www.nanowerk.com - May 9, 2014 8:47 AM

Gust MEES's insight:

Biomedical engineering researchers have developed a nanotechnology anti-cancer drug delivery method that essentially smuggles the drug into a cancer cell before triggering its release ("Enhanced Anticancer Efficacy by ATP-Mediated Liposomal Drug Delivery"). The method can be likened to keeping a cancer-killing bomb and its detonator separate until they are inside a cancer cell, where they then combine to destroy the cell.

'Glowing' new nanotechnology guides cancer surgery, also kills remaining malignant cells | 21st Century Innovative Technologies and Developments as also discoveries, curiosity ( insolite)... | Scoop.it

From www.nanowerk.com - January 5, 2015 1:41 PM

Gust MEES's insight:

A new system developed at Oregon State University to improve cancer surgery uses a nanoparticle called a dendrimer to carry a drug into cancer cells, that can set the stage for improved surgery and also phototherapy. (Graphic courtesy of Oregon State University)

Technology such as this, scientists said, may have a promising future in the identification and surgical removal of malignant tumors, as well as using near-infrared light therapies that can kill remaining cancer cells, both by mild heating of them and generating reactive oxygen species that can also kill them.
