Simple, Effective Method to Untangle DNA

Simple, Effective Method to Untangle DNA

Researchers have long sought an efficient way to untangle DNA in order to study its structure – neatly unraveled and straightened out – under a microscope. Now, chemists and engineers at KU Leuven, in Belgium, have devised a strikingly simple and effective solution: they inject genetic material into a droplet of water and use a pipet tip to drag it over a glass plate covered with a sticky polymer. The droplet rolls like a ball over the plate, sticking the DNA to the plate surface. The unraveled DNA can then be studied under a microscope. The researchers described the technique in the journal ACS Nano. [More]
Garden Center Spider Could Inspire New Way to Make Nanofibers

Garden Center Spider Could Inspire New Way to Make Nanofibers

A spider commonly found in garden centres in Britain is giving fresh insights into how to spin incredibly long and strong fibres just a few nanometres thick. [More]
Rapid Diagnostic Test for Ebola and Other Fevers Using Multicolored Nanoparticles

Rapid Diagnostic Test for Ebola and Other Fevers Using Multicolored Nanoparticles

When diagnosing a case of Ebola, time is of the essence. However, existing diagnostic tests take at least a day or two to yield results, preventing health care workers from quickly determining whether a patient needs immediate treatment and isolation. [More]
Intercellular Nanotubes Help Bacteria Exchange Nutrients

Intercellular Nanotubes Help Bacteria Exchange Nutrients

Bacteria usually live in species-rich communities and frequently exchange nutrients and other metabolites. Until now, it was unclear whether microorganisms exchange metabolites exclusively by releasing them into the surrounding environment or whether they also use direct connections between cells for this purpose.

Tiny Molecule Holds Potential to Decrease Likelihood of Alcohol-Related Cancers in At-Risk Population

Tiny Molecule Holds Potential to Decrease Likelihood of Alcohol-Related Cancers in At-Risk Population

Researchers at the Stanford University School of Medicine have found that by changing the selectivity of an enzyme, a small molecule could potentially be used to decrease the likelihood of alcohol-related cancers in an at-risk population. [More]
DNA Minicircles Show Promise for Early Detection of Cancer

DNA Minicircles Show Promise for Early Detection of Cancer

Imagine: You pop a pill into your mouth and swallow it. It dissolves, releasing tiny particles that are absorbed and cause only cancerous cells to secrete a specific protein into your bloodstream. Two days from now, a finger-prick blood sample will expose whether you've got cancer and even give a rough idea of its extent. [More]
Researchers Devise Innovative Clot-Busting Technique Using Magnetic Nanoparticles

Researchers Devise Innovative Clot-Busting Technique Using Magnetic Nanoparticles

By loading magnetic nanoparticles with drugs and dressing them in biochemical camouflage, Houston Methodist researchers say they can destroy blood clots 100 to 1,000 times faster than a commonly used clot-busting technique. [More]
New, Low-Cost Method to Build DNA Nanotubes Block by Block

New, Low-Cost Method to Build DNA Nanotubes Block by Block

Researchers at McGill University have developed a new, low-cost method to build DNA nanotubes block by block - a breakthrough that could help pave the way for scaffolds made from DNA strands to be used in applications such as optical and electronic devices or smart drug-delivery systems. [More]
Durable Nanocomposite Antibacterial Coatings to Reduce Rate of Infections

Durable Nanocomposite Antibacterial Coatings to Reduce Rate of Infections

Ruthless with bacteria, harmless to human cells. New, durable antibacterial coatings of nanocomposites, developed at the Institute of Physical Chemistry of the Polish Academy of Sciences in Warsaw, will in future help to improve the hygiene of sportswear, and used in medicine, will reduce the rate of infections and shorten the times of in-patient hospital admissions.

Latest Insights on Cellulose Nanocrystal Toxicity

Latest Insights on Cellulose Nanocrystal Toxicity

Novel nanomaterials derived from cellulose have many promising industrial applications, are biobased and biodegradable, and can be produced at relatively low cost. Their potential toxicity--whether ingested, inhaled, on contact with the skin, or on exposure to cells within the body--is a topic of intense discussion, and the latest evidence and insights on cellulose nanocrystal toxicity are presented in a Review article in Industrial Biotechnology, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers. The article is available on the Industrial Biotechnology website. [More]
