A study published in ACS Nano presents a novel biosensor for the isothermal, highly sensitive detection of bladder cancer biomarkers—miRNAs, short non-coding RNAs that regulate gene expression—using programmable pH-responsive triplex DNA nanostructures.

Skoltech researchers have fashioned a microstructure made of modified glass fiber that could in principle function as a tiny lantern for medical probes exploring the interior of blood vessels and other tubular cavities in the body.

Natural and engineered systems have a whole world of chemistry inside their tiny pores—known as nanopores—that changes depending on the chemical functional groups inside.

Vibrational sum-frequency generation (VSFG) is a nonlinear spectroscopic method widely used to investigate the molecular structure and dynamics of surface systems. However, in far-field observations, the spatial resolution of this method is constrained by

As demand for energy-intensive computing grows, researchers at the Department of Energy's Oak Ridge National Laboratory have developed a new technique that lets scientists see—in unprecedented detail—how interfaces move in promising materials for computi

A team of researchers from Brown University has developed a new nanotechnology-based approach that could improve treatment of fungal infections, particularly those caused by the increasingly drug-resistant Candida species.

RIKEN chemists have hit upon a fast and easy way to combine so-called nanobelts of carbon with sulfur-containing functional groups. The work is published in the journal Nature Communications.

Controlling the topology and structure of entangled molecular strands is a key challenge in molecular engineering, particularly when attempting to create large nanostructures that mimic biological systems. Examples found in nature, such as virus capsids a

The move from two to three dimensions can have a significant impact on how a system behaves, whether it is folding a sheet of paper into a paper airplane or twisting a wire into a helical spring. At the nanoscale, 1,000 times smaller than a human hair, on

Carbyne, a one-dimensional chain of carbon atoms, is incredibly strong for being so thin, making it an intriguing possibility for use in next-generation electronics, but its extreme instability causing it to bend and snap on itself made it nearly impossib

Ferroelectrics are a class of materials that exhibit so-called spontaneous electric polarization, which is the separation of electric charges that can be reversed when an external electric field is applied to them. The dipole moments (i.e., pairs of equal

Augmented-reality (AR) technology is rapidly finding its way into everyday life, from education and health care to gaming and entertainment. However, the core AR device remains bulky and heavy, making prolonged wear uncomfortable. A breakthrough from POST
