The Korea Research Institute of Standards and Science has successfully developed a length measurement system that achieves a ...

Micrometer-scale patterned surfaces were produced using a contact mask in conjunction with a frequency-doubled argon ion laser (λ = 244 nm). Near-field optical exposure was carried out by coupling the ...

The scale of nano-sized objects requires very precise position determination. The state-of-the-art manipulators involve accurate nanometer positioning. This paper presents the design, fabrication ...

Here we report on a bioresorbable fluorescence sensor for in vivo pH monitoring. The sensor leverages a nanometer-thick multilayer stack of polyelectrolytes labelled with a pH-insensitive fluorophore ...

These new chips will make devices last longer on battery and run much faster, which is good for everything from phones to big computers. The demand for 3 nm chips is growing fast, especially in areas ...

With a light microscope, we can distinguish objects at the scale of the wavelengths of visible light just under a micrometer. Around 1870 Ernst Abbe, who laid the foundation of modern optics, ...

Micro/nanoplastics (MNPs), plastic particles and fibers with sizes ranging from nanometers (≥ 1 nm) to micrometers (≤ 5 mm) have become emerging environmental pollutants and are widely ...

Nanophotonic sensors offer precision, remote read-out, and immunity to electromagnetic interference but face adoption challenges due to complex, costly readout instrumentation, typically based on high ...
