Femtolitre Volume cryoEM Sample Preparation Using a Force‐Sensitive Microfluidic Cantilever

open access: yesAdvanced Materials Technologies, EarlyView.
Cryogenic electron microscopy enables structural imaging of biological molecules, but current methods lack targeted extraction of subcellular content for direct vitrification. This study introduces a force‐sensitive microfluidic cantilever pipette that aspirates and dispenses femtolitre volumes from individual cells onto electron microscopy grids.

A Dual‐Emissive DNA‐Templated Silver Nanocluster with Near‐Infrared I and II Emission

open access: yesAdvanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
This study presents a dual‐emissive DNA‐stabilized silver nanocluster with a nanosecond‐lived NIR‐I emission band and a microsecond‐lived NIR‐II emission band. Mass spectrometry establishes that the nanocluster has molecular formula (DNA)2[Ag17]11+. DNA sequence variations reveal critical nucleobases for stabilization, and modifications at the DNA 5 ...

Unraveling the Role of Surfactants in Micelle‐Templated Growth of Chiral Plasmonic Nanoparticles

open access: yesAdvanced Optical Materials, EarlyView.
Micelle template‐directed growth enables precise control over the chiroptical properties of gold nanorods. Comparison of surfactants with varying aliphatic tail lengths shows that longer tails increase groove inclination and reduce groove density. Optimized conditions for the longest‐tail surfactant (C18) yield slightly higher g‐factors than those ...
