NTSB Challenges and Expectations for 2021 | Holland & Knight LLP

The National Transportation Safety Board (NTSB) investigates, reports on and determines the probable causes of transportation accidents in all modes of transportation, from planes, trains and automobiles, to pipelines, ships and other accidents of a catastrophic or recurring nature, such as commercial space transportation accidents and accidents involving hazardous materials.
1 When the NTSB identifies safety issues, it can make safety recommendations aimed at furthering its ultimate mission of preventing future accidents and reducing injuries from accidents that do occur.
Every two years, the NTSB publishes a Most Wanted List of safety improvements that the agency determines are important to preventing accidents, minimizing injuries and saving lives across all modes of transportation. On the eve of the Biden-Harris inauguration, Holland & Knight spoke with NTSB Chairman Robert Sumwalt about current agency sa ....

Rapid Antibody Testing For COVID-19

Rapid Antibody Testing For COVID-19

An advanced nanomaterial-based biosensing platform has been found by the researchers that detects antibodies specific to SARS-CoV-2, the virus responsible for the COVID-19 pandemic within seconds. Additional to testing, this platform will help to quantify patient immunological response to the new vaccines with precision.
The study conducted by researchers at Carnegie Mellon University in collaboration with University of Pittsburgh (Pitt) and the UPMC is published in the journal
Advanced Materials.
The testing platform identified the presence of two virus antibodies- spike S1 protein and receptor binding domain (RBD), in a very small drop of blood. Antibody concentrations can also be detected in low concentrations and this detection happens through an electrochemical reaction within a handheld microfluidic device which sends results almost immediately to ....

Microfluidic chip detects COVID antibodies in seconds

“We utilised the latest advances in materials and manufacturing such as nanoparticle 3D printing to create a device that rapidly detects COVID-19 antibodies,” said Rahul Panat, an associate professor of mechanical engineering at Carnegie Mellon who uses specialised additive manufacturing techniques across his biomedical research.
To create the device, the team used an additive technique known as aerosol jet 3D printing. Tiny, inexpensive gold micropillar electrodes were printed at nanoscale by thermally sintering aerosol droplets together. This causes a rough, irregular surface that provides increased surface area of the micropillars and an enhanced electrochemical reaction, where antibodies can latch on to antigens coated on the electrode. The specific geometry allows the micropillars to load more proteins for detection, resulting in very accurate, quick results. ....

Researchers at Carnegie Mellon University have developed an advanced nanomaterial-based biosensing platform that detects, within seconds, antibodies specific to SARS-CoV-2 or the coronavirus. It also helps to assess patient immunological response to the new vaccine.
The study, published in the journal
Advanced Materials, is Carnegie Mellon’s collaboration with the University of Pittsburgh (Pitt) and the UPMC.
The testing platform identifies the presence of two of the virus’ antibodies, spike S1 protein and receptor binding domain (RBD), in a very small drop of blood (about 5 microliters). Antibody concentrations can be extremely low and still detected below one picomolar (0.15 nanograms per milliliter). This detection happens through an electrochemical reaction within a handheld microfluidic device which sends re ....
