Imaging system helps surgeons remove tiny ovarian tumors

Ovarian cancer is usually diagnosed only after it has reached an advanced stage, with many tumors spread throughout the abdomen. Most patients undergo surgery to remove as many of these tumors as possible, but because some ...

'Nanofiber yarn' makes for stretchy, protective artificial tissue

The human body is held together by an intricate cable system of tendons and muscles, engineered by nature to be tough and highly stretchable. An injury to any of these tissues, particularly in a major joint like the shoulder ...

New nanomedicine slips through the cracks

In a recent study in mice, researchers found a way to deliver specific drugs to parts of the body that are exceptionally difficult to access. Their Y-shaped block catiomer (YBC) binds with certain therapeutic materials forming ...

Nanoscale magnetic imaging of ferritin in a single cell

In life sciences, the ability to measure the distribution of biomolecules inside a cell in situ is an important investigative goal. Among a variety of techniques, scientists have used magnetic imaging (MI) based on the nitrogen ...

A light-activated remote control for cells

What if doctors had a remote control that they could use to steer a patient's own cells to a wound to speed up the healing process? Although such a device is still far from reality, researchers reporting in the ACS journal ...

Carriers deliver controllable cancer chemotherapy

Cancer kills more than half a million men, women, and children each year in the U.S, and chemotherapy is only slightly more discriminating than the disease it treats. As a result, many cancer treatments kill cells throughout ...

Harnessing microorganisms for smart microsystems

A research team at the Department of Mechanical Engineering at Toyohashi University of Technology has developed a method to construct a biohybrid system that incorporates Vorticella microorganisms. The method allows movable ...

Black nanoparticles slow the growth of tumors

The dark skin pigment melanin protects against the sun's damaging rays by absorbing light energy and converting it to heat. This could make it a very effective tool in tumor diagnosis and treatment, as demonstrated by a team ...

Magnetic nanoparticles can 'burn' cancer cells

Unfortunately, cancer isn't simply a single disease, and some types, like pancreas, brain or liver tumours, are still difficult to treat with chemotherapy, radiation therapy or surgery, leading to low survival rates for patients. ...

Nanomaterials give plants 'super' abilities

Science-fiction writers have long envisioned human¬-machine hybrids that wield extraordinary powers. However, "super plants" with integrated nanomaterials may be much closer to reality than cyborgs. Today, scientists report ...

Next-generation single-dose antidotes for opioid overdoses

The U.S. opioid epidemic is being driven by an unprecedented surge in deaths from fentanyl and other synthetic opiates. Fentanyl's powerful effects are long-lasting, and even tiny amounts of the drug can lead to an overdose. ...

Nanovaccine boosts immunity in sufferers of metabolic syndrome

A new class of biomaterial developed by Cornell researchers for an infectious disease nanovaccine effectively boosted immunity in mice with metabolic disorders linked to gut bacteria – a population that shows resistance ...

Lipid vesicles transmit luminous or electrical signals

Liposomes are small spherical vesicles with walls comprising two layers of lipids and containing an aqueous core. These artificial structures have been developed for drug delivery or as carriers of active substances in cosmetic ...

Cellular microRNA detection with miRacles

MicroRNAs (miRNAs) are short noncoding regulatory RNAs that can repress gene expression post-transcriptionally and are therefore increasingly used as biomarkers of disease. Detecting miRNAs can be arduous and expensive as ...
