Using Mathematics to Predict Geometries of Nanoparticles Could Help Scientists Design New Vaccines

Scientists at the Universities of York and Torino have used mathematics as a tool to provide precise details of the structure of protein nanoparticles, potentially making them more useful in vaccine design.

Innovative Microscopic Nanoparticle of Indomethacin Could Help Control Preterm Birth

Innovative Microscopic Nanoparticle of Indomethacin Could Help Control Preterm Birth

Using nanoparticles to engineer a special drug, a team of researchers has demonstrated in mice a new way to both reduce preterm birth and avoid the risks of medication in pregnancy to unborn babies.

Flexible Cellulose Nanogenerators Could Potentially Power Biomedical Devices Inside the Body

Flexible Cellulose Nanogenerators Could Potentially Power Biomedical Devices Inside the Body

Implantable electronics that can deliver drugs, monitor vital signs and perform other health-related roles are on the horizon. But finding a way to power them remains a challenge. Now scientists have built a flexible nanogenerator out of cellulose, an abundant natural material, that could potentially harvest energy from the body -- its heartbeats, blood flow and other almost imperceptible but constant movements. Their report appears in the journal ACS Applied Materials & Interfaces.

New Handheld, Miniature Microscope Could Help Surgeons Identify Cancerous Cells

New Handheld, Miniature Microscope Could Help Surgeons Identify Cancerous Cells

Surgeons removing a malignant brain tumor don’t want to leave cancerous material behind. But they’re also trying to protect healthy brain matter and minimize neurological harm.

UT Southwestern Scientists Create Synthetic 'Dendrimer' Nanoparticles that Can Deliver Drugs to Tumor Cells

UT Southwestern Scientists Create Synthetic 'Dendrimer' Nanoparticles that Can Deliver Drugs to Tumor Cells

UT Southwestern Medical Center chemists have successfully used synthetic nanoparticles to deliver tumor-suppressing therapies to diseased livers with cancer, an important hurdle scientists have been struggling to conquer.

New Lattice Filter Could Be Powerful Tool for Analysing Low Contrast Cryo-Images of 3D Protein Nanocrystals

New Lattice Filter Could Be Powerful Tool for Analysing Low Contrast Cryo-Images of 3D Protein Nanocrystals

When cryoEM images are obtained from protein nanocrystals the images themselves can appear to be devoid of any contrast. A group of scientists from the Netherlands have now demonstrated that lattice information can be revealed and enhanced by a specialized filter.

New Light-Activated Nanotherapy Suggested for Terminating Antibiotic-Resistant Bacteria

New Light-Activated Nanotherapy Suggested for Terminating Antibiotic-Resistant Bacteria

Scientists at the University of Colorado Boulder have proposed a light-activated and adaptive nanotherapy. They propose that the new therapy will help humans to fight-off drug-resistant bacteria.

Exosomes Show Better Cancer-Killing Effect with Less Chemo

Exosomes Show Better Cancer-Killing Effect with Less Chemo

The cancer drug paclitaxel just got more effective. For the first time, researchers from the University of North Carolina at Chapel Hill have packaged it in containers derived from a patient’s own immune system, protecting the drug from being destroyed by the body’s own defenses and bringing the entire payload to the tumor.

Development of Novel Nanoprobe Leads to Greater Understanding of How Proteins Attach to DNA

Development of Novel Nanoprobe Leads to Greater Understanding of How Proteins Attach to DNA

New research directed by Dr Neil Kad, of the School of Biosciences, has led to the use of the nanoprobe to study how individual proteins interact with DNA. Invisible to the human eye, this tiny triangular probe can be captured using laser tweezers and then moved around inside a microscope chamber.
