Researchers Develop Sensitive Ricin Biosensors Based on Aptamers

Researchers Develop Sensitive Ricin Biosensors Based on Aptamers

Tiny rocketlike particles that move around on their own in a hydrogen peroxide solution can detect trace amounts of the lethal toxin ricin within minutes (ACS Sens. 2016, DOI: 10.1021/acssensors.5b00300). They could someday provide a quick, easy way to detect the bioterrorism agent in food and water samples without having to bring them back to a lab. The particles, made of graphene oxide and platinum, carry sensor molecules that glow when they bind to ricin.

New Nanoparticle Therapy Holds Potential for Safe Treatment of Liver Cancer

New Nanoparticle Therapy Holds Potential for Safe Treatment of Liver Cancer

Researchers from UT Southwestern Medical Center have reported on an experimental nanoparticle therapy, which incorporates low-density lipoproteins (LDL) and fish oil to selectively destroy liver cancer cells without affecting the healthy cells.

Researchers Develop Nanoparticles to Help Restrict Growth of Cancerous Tumors

Researchers Develop Nanoparticles to Help Restrict Growth of Cancerous Tumors

A new technique to restrict the growth of cancerous tumors has been developed by a group of engineers from the Washington University in St. Louis. The group used nanoparticles from the core ingredient in the commonly used antacid tablets.

Hollow Crystal Spheres Could Lead to New Drug Delivery Platform

Hollow Crystal Spheres Could Lead to New Drug Delivery Platform

A Drexel University materials scientist has discovered a way to grow a crystal ball in a lab. Not the kind that soothsayers use to predict the future, but a microscopic version that could be used to encapsulate medication in a way that would allow it to deliver its curative payload more effectively inside the body.

Researchers Demonstrate Safe Interaction of Graphene with Nerve Cells

Researchers Demonstrate Safe Interaction of Graphene with Nerve Cells

Graphene is a two-dimensional form of carbon, and successful demonstrations have been carried out by researchers to prove the possibility of interfacing graphene with nerve cells, or neurons, without affecting their integrity.

Blood Serum Proteins Prompt Gold Nanoparticles to Aggregate

Blood Serum Proteins Prompt Gold Nanoparticles to Aggregate

Blood serum proteins have been observed combining one-to-one with gold nanoparticles and prompting them to aggregate, scientists at Rice University reported.

Researchers from MGH Develop New Nanoparticle for Treating Pancreatic Cancer

Researchers from MGH Develop New Nanoparticle for Treating Pancreatic Cancer

Nature Nanotechnology, an online manual, has published a report outlining the concept of combining nanoparticles with molecular and photodynamic therapies in order to deliver anticancer treatment, and obtain improved results for patients with pancreatic cancer and other treatment-resistant tumors. The concept has been developed by a team of researchers from the Wellman Center for Photomedicine at Massachusetts General Hospital (MGH).

New Method for Fast and Precise DNA Sequencing is Simulated

New Method for Fast and Precise DNA Sequencing is Simulated

An innovative method for fast and precise gene sequencing has been proposed by scientists at the National Institute of Standards and Technology (NIST).

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.

A Method of Producing DNA-Encoded Nanoparticles has been Developed

A Method of Producing DNA-Encoded Nanoparticles has been Developed

A novel technique that uses DNA to encode information on the surface of gold nanoparticles has been developed. This new method can be used to control the 3D structure of nanoparticle assemblies in nanodevice fabrication or to produce nanoparticles that will bind to and kill tumor cells.
