A group of Brazilian researchers has developed a nanomaterials-based ointment to treat skin cancer in its early and intermediate stages.

The team of researchers at the Universidad de São Paulo, responsible for development, has tested the product in three Brazilian hospitals during a year, giving some very encouraging results.

Nanomaterials of ointment bind selectively to cancer cells, after which a laser light is applied to generate a series of chemical reactions.

This technique has a lower toxicity, remaining in the body significantly less time than other alternatives. This photodynamic therapy is not effective against more aggressive tumours such as malignant melanomas and should be subjected to another series of tests prior to marketing.

The detection of cancer through blood or saliva samples would facilitate early detection and make it less traumatic for the patient.

This is the goal of a group of Argentine researchers who are developing a nanobiosensor from carbon nanotubes.

This nanobiosensor consists of two microelectrodes connected by a bridge of nanotubes with antibodies. Since electrical signals produced by the union of a tumour with the sensor molecule biosensor it detects the appearance of a tumour.

The development is part of the project Nodo Nanotec, funded by the Comisión Nacional de Energía Atómica and the Agencia de Promoción Científica y Tecnológica. The Universidad Nacional de Bahía Blanca and the Instituto de Investigaciones Científicas y Técnicas para la Defensa are also collaborating.

NN-Labs (Nanomaterials & Nanofabrication Laboratories) has developed an alternative to cadmium seleneide-based quantum dots (CdSe) free of heavy metals. This alternative, indium phosphide, introduced in April this year, provides high performance while eliminating the use of cadmium.

The company NN-Labs, which was born as a spin-off from the University of Arkansas, has announced the release, in May this year, a U.S. patent entitled ‘Synthetic Control of Metal Oxide Nanocrystal Shapes and Sizes’ to describe a method to synthesize metal oxide nanocrystals by controlling their size, shape and distribution.

During this month of June, the mentioned company has received a Phase I SBIR award from the National Science Foundation for a project entitled ‘Highly luminescent Maganese-Doped Zinc Selenide Quantum Dots to Enhance Silicon Solar Cell Spectral Efficiency Through Down-Conversion’ which attempts to demonstrate the enrichment efficiency of a polycrystalline silicon solar cell through spectral downconverter overlayer containing metal ion-doped quantum dot nanocrystals.

A spin-off from the University of Twente, called Ostendum, developed the first prototype of a biosensor that can detect within minutes if someone is infected with a virus. The company expects to have his version in the market in 2010.

The device consists of two parts: a lab-on-a-chip system, and a detector. The chip contains tiny channels coated with receptors. With the help of a fluidic system is transported to blood or saliva to the canals. Then substances in saliva or blood can bind to receptors on the chip. A laser light is guided through the channels. The phase of this light is altered by any substance bound to the receptors in any of the channels. Such change will be manifested in the pattern of inference, thereby demonstrating the presence of a virus. The method is highly sensitive and may detect the presence of a viral particle.
