The built-in tools of ants have been imaged in atomic detail for the first time by materials scientist Arun Devaraj.
Using DNA, scientists organized bioactive proteins in desired 2-D and 3-D ordered arrays—promising for structural biology, biomedicine, and more.
The Engineering Division of the Council on Undergraduate Research announces the 2021 recipients of its Mentoring Awards and winners of its Student Video Competition.
In APL Bioengineering, researchers have developed materials that can interface with an injured spinal cord and provide a scaffolding to facilitate healing. To do this, scaffolding materials need to mimic the natural spinal cord tissue, so they can be readily populated by native cells in the spinal cord, essentially filling in gaps left by injury. The researchers show how the pores improve efficiency of gene therapies administered locally to the injured tissues, which can further promote tissue regeneration.
David Kaplan, the Stern Family Professor of Engineering at Tufts University School of Engineering, has been elected to the National Academy of Engineering in recognition of his contributions to silk-based materials for tissue engineering and regenerative medicine.
Advances in the fields of biomaterials and nanotechnology could lead to big breakthroughs in the fight against dangerous viruses like the novel coronavirus that causes COVID-19. In APL Bioengineering, researchers from the Indian Institute of Science describe possibilities being explored by scientists, combining biomaterials and nanotechnology, to make vaccines more effective and build surfaces that could fight and kill viruses on their own.
Lawrence Livermore National Laboratory scientists have developed a new method for 3D printing living microbes in controlled patterns, expanding the potential for using engineered bacteria to recover rare-earth metals, clean wastewater, detect uranium and more.
Examining the structure of a sunflower stem as it matures can help both the plant scientist and the biomaterials engineer.
Researchers combined gas foaming and 3D molding technologies to quickly transform electrospun membranes into complex 3D shapes for biomedical applications. The new approach demonstrates significant improvements in speed and quality compared with other methods, and is the first successful demonstration of formation of 3D neural tissue constructs with an ordered structure through differentiation of human neural progenitor/stem cells on these transformed 3D nanofiber scaffolds. They discuss their work in this week’s Applied Physics Reviews.
Rutgers’ RUCDR Infinite Biologics received an amended emergency use authorization from the FDA late Thursday for the first SARS-CoV-2 coronavirus test that will allow people to collect their own saliva at home and send to a lab for results. The decision follows the FDA’s recent emergency approval to RUCDR Infinite Biologics for the first saliva-based test, which involves health care workers collecting saliva from individuals at testing sites.
Rutgers’ RUCDR Infinite Biologics has launched a test for the SARS-CoV-2 coronavirus and is using its automation experience and infrastructure to test as many as tens of thousands of samples daily. RUCDR has also submitted an emergency use authorization request for a saliva collection method that will allow for broader population screening.
Biohydrogels have been studied closely for their potential use in biomedical applications, but they often move between sols and gels, depending on their temperature, changes that can pose issues depending on the intended use. In Physics of Fluids, researchers discuss their work studying the effect of temperature on hydrogels. They found that creating hydrogels at room temperature or below results in more robust materials that function more effectively when used in the body.
Proteins are the building blocks of life and scientists have long studied how to improve them or design new ones. Traditionally, new proteins are created by mimicking existing proteins or manually editing their amino acids. This process is time-consuming, and it is difficult to predict the impact of changing an amino acid. In APL Bioengineering, researchers explore how to create new proteins by using machine learning to translate protein structures into musical scores, presenting an unusual way to translate physics concepts across domains.
Scientists at the Department of Energy’s Oak Ridge National Laboratory have developed a new method to peer deep into the nanostructure of biomaterials without damaging the sample. This novel technique can confirm structural features in starch, a carbohydrate important in biofuel production.
Two biophysicists at the University of Wisconsin-Milwaukee have introduced a method that could turn protein hydrogels into smart materials with shape-memory capabilities. The work opens the door for a wider use of protein hydrogels in both conventional and new fields, like soft robotics.
