Super-resolution microscopes achieve nanometer resolution without traditional on/off switching
Use the diffraction maximum and minimum light to solve two inelastic point scatterers. Credit: Nature Physics (2025). doi:10.1038/s41567-024-02760-1 Overcoming resolution limitations with light microscopes at approximately half the wavelength of light (approximately 250 nanometers) is one of the most important developments in optics. Due to the nature of the light waves, even the best lenses cannot produce light spots smaller…

New perovskite growth method enables ultra-high resolution micro-LED displays
Remotely epitaxial crystalline perovskites for ultra-high resolution micro-LED displays. Credit: Professor Wu Yuchen’s group Microscale light-emitting diodes (micro-LEDs) are emerging as the next generation display technology for optical communications, augmented and virtual reality, and wearable devices. Metal halide perovskites show great potential for efficient light emission, long-range carrier transport, and scalable fabrication, and could be ideal candidates for bright LED…

Atomic force microscopy reveals microtubule defects with submolecular resolution
Figure 1. High-resolution AFM images of the inner and outer surfaces of microtubules. Credit: Nano Letters (2024). DOI: 10.1021/acs.nanolett.4c04294 In a study recently published in the journal Nano Letters, researchers at Kanazawa University Nano Life Science Institute (WPI-NanoLSI) used frequency-modulated atomic force microscopy to examine the inner surfaces of microtubules (MTs) and microtubules. We revealed the submolecular structure of the…
