Nanotechnology drug delivery shows promise for improved melanoma treatment

Researchers have developed a new three-drug delivery system for cancer treatment, especially metastatic melanoma, the deadliest form of skin cancer - and shown that the system may have particular value with cancers like this that often spread through the lymphatic system.

Superhydrophobic coating protects without the price

A new class of superhydrophobic nanomaterials might simplify the process of protecting surfaces from water.

Nanostructured metal coatings let the light through for electrical devices

Light and electricity dance a complicated tango in devices like LEDs, solar cells and sensors. A new anti-reflection coating lets light through without hampering the flow of electricity, a step that could increase efficiency in such devices.

Fluorescent nanotubes help assess meat spoilage

Scientists report a simple method that uses nanotubes to quickly detect spoilage. It could help make sure meats are safe when they hit store shelves.

Ratiometric sensing of toxins using quantum dots

Botulinum neurotoxin (BoNT) presents a significant hazard under numerous realistic scenarios. BoNT is the most toxic substance known. Current tests for BoNT are slow (2 days), lab-based, and complex. A new scheme offers quick, specific quantification by non-specialized personnel such as first responders in the field.

New nanoparticles pack one-two punch against cancer

Layer-by-layer nanoparticles enable efficient delivery of multiple drugs into cancer cells.

Detecting and identifying explosives with quantum dots

The proof-of-concept sensor is designed to quickly identify and quantify five commonly used explosives in solution to help track toxic contamination in waste water and improve the safety of public spaces.

Highly efficient biomimetic membrane can potentially lower cost of water purification by 30 per cent

Inspired by the mangrove plant and human kidney, this novel biomimetic membrane is mechanically stronger and allows only water molecules to pass through.

New nanotechnology manufacturing technique advances imaging, biosensing technology

Researchers invented a novel way to build nanolenses in large arrays using a combination of chemical and lithographic techniques.
