A general rule in optics is that light is insensitive to features which are much smaller than the optical wavelength. However, a new experiment shows that even features that are more than 100 times smaller than the wavelength can still be sensed by light.
Researchers propose a new way of performing in vitro tests on nanoparticles that could enhance a correlation to in vivo results. This involves reproducing in the lab the dynamic and fluidic variations that these particles experience in the human body.
Scientists have fabricated antibody-coated porous silicon nanoparticles that can actively target cells through binding to specific cell-surface
receptors. These nanoparticles were demonstrated to selectively deliver multiple therapeutics to human B cells in vitro.
Scientists have developed an Earth-abundant catalyst based on copper-oxide nanowires modified with tin oxide. A solar-driven system set up using this catalyst was able to split CO2 with an efficiency of 13.4%.
Researchers demonstrate the design and fabrication of stretchable tactile sensors that are 3D printed under ambient conditions via a combination of nanocomposite ink optimization, 3D imaging, and multimaterial 3D printing.
Researchers create a huge variety of programmed three-dimensional shapes out of single strands of synthetic DNA, a process known as DNA origami. These nanoparticles may ultimately be deployed as structural scaffolds to deliver vaccines, drugs, or even gene-editing tools such as CRISPR-Cas9 to specific parts of the body, he says.
Nondestructive scanning near-field thickness resonance acoustic microscopy (SNTRAM) with sharp phase contrast and mechanical sensitivity provides a wide range of applications in nanomechanical imaging of semiconductor structures and a wide range of other materials.
Researchers present a facile approach to overcoming hysteresis to less than 0.5% of the gate-source voltage sweep range: rather than to eliminate traps, they aim to reduce the effect that traps have on the CNTs.
