An Improved Method for Coating Gold Nanorods
Researchers have fine-tuned a technique for coating gold nanorods with silica shells, allowing engineers to create large quantities of the nanorods and giving them more control over the thickness of the shell. Gold nanorods are being investigated for use in a wide variety of biomedical applications.
New Technique Helps Probe Performance of Organic Solar Cell Materials
Researchers have developed a way to determine the role that a material’s structure has on the efficiency of organic solar cells, which are candidates for low-cost, next generation solar power. The finding will help guide future research and development efforts.
Wearable Sensor Smooths Path to Long-Term EKG, EMG Monitoring
Researchers have developed a wearable sensor that uses silver nanowires to monitor electrophysiological signals. The sensor is as accurate as the “wet electrode” sensors used in hospitals for EKGs and EMGs, but can be used for long-term monitoring and is more accurate than existing sensors when a patient is moving.
‘Flying Carpet’ Technique Uses Graphene to Deliver One-Two Punch of Anticancer Drugs
Researchers develop nanoscale “flying carpets” to deliver anticancer drugs directly to targeted parts of cancer cells.
Nanoparticle Allows Low-Cost Creation of 3-D Nanostructures
Researchers have developed a new lithography technique that uses nanoscale spheres to create 3-D structures with biomedical, electronic and photonic applications.
Nutrition, Safety Key To Consumer Acceptance of Nanotech, Genetic Modification In Foods
New research shows that the majority of consumers will accept the presence of nanotechnology or genetic modification technology in foods – but only if the technology enhances the nutrition or improves the safety of the food.
Researchers Find New Way to Move Atomically Thin Semiconductors for Use in Extremely Flexible Devices
Researchers have developed a new way to transfer thin semiconductor films, which are only one atom thick, onto arbitrary substrates, paving the way for flexible computing or photonic devices.
Bio-Inspired ‘Nano-Cocoons’ Offer Targeted Drug Delivery Against Cancer Cells
Researchers have developed a drug delivery system consisting of nanoscale “cocoons” made of DNA that target cancer cells and trick the cells into absorbing the cocoon before unleashing anticancer drugs.
Coating Nanotubes With Aluminum Oxide Lowers Risk of Lung Injury
A new study finds that coating multiwalled carbon nanotubes with aluminum oxide reduces the risk of lung scarring, or pulmonary fibrosis, in mice.
New Method Sneaks Drugs Into Cancer Cells Before Triggering Release
Biomedical engineering researchers have developed an anti-cancer drug delivery method that essentially smuggles the drug into a cancer cell before triggering its release. The method can be likened to keeping a cancer-killing bomb and its detonator separate until they are […]
