Novel photolithographic technology that enables control over functional shapes of microstructures

Researchers have developed a novel photolithographic technology enabling control over the functional shapes of micropatterns using oxygen diffusion.

Researchers develop a harmless artificial virus for gene therapy

Researchers managed to create artificial viruses, protein complexes with the ability of self-assembling and forming nanoparticles which are capable of surrounding DNA fragments, penetrating the cells and reaching the nucleus in a very efficient manner, where they then release the therapeutic DNA fragments. The achievement represents an alternative with no biological risk to the use of viruses in gene therapy.

Unraveling the origin of the pseudogap in a charge density wave compound

By combining a variety of different experimental techniques and theory, scientistsobtained unique insights into the nature of the pseudogap state in a canonical charge density wave material.

Scientists use ultrasound waves to produce fullerene

Researchers used a simple, fast and effective method to produce fullerene nanostructures by applying ultrasound waves.

Researchers deliver large particles into cells at high speed

Device can insert 'cargo' into 100,000 cells per minute, up from current standard of 1 per minute.

Scientists program the lifetime of self-assembled nanostructures

Researchers developed an aqueous system that uses a single starting point to induce self-assembly formation, whose stability is pre-programmed with a lifetime before disassembly occurs without any additional external signal - hence presenting an artificial self-regulation mechanism in closed conditions.

Engineers devise optical method for producing high-res, 3-D images of nanoscale objects (w/video)

The technique, called cathodoluminescence tomography, could assist in the development of high-efficiency solar cells and LEDS, or improve the way biological systems are visualized.
