DNA Origami Uptake in Y‐79 Retinoblastoma Cells Driven by Oligolysine Coating

Small Structures, Volume 7, Issue 10, October 2026.
We show that polymeric coating can enable DNA origami nanoparticle internalization into ocular retinoblastoma cells. Not only are the coated nanoparticles well‐tolerable to the cells, but they also remain mobile in the vitreous of a porcine ex vivo model.

Reactivatable stimulated emission depletion microscopy using fluorescence-recoverable nanographene

Nature Communications
Stimulated emission depletion (STED) microscopy, a key optical super-resolution imaging method, has extended our ability to view details to resolution levels of tens of nanometers.

Click Chemistry with Cell-Permeable Fluorophores Expands the Choice of Bioorthogonal Markers for Two-Color Live-Cell STED Nanoscopy

Cells
STED nanoscopy allows for the direct observation of dynamic processes in living cells and tissues with diffraction-unlimited resolution. Although fluorescent proteins can be used for STED imaging, these labels are often outperformed in photostability by ...

Nanorulers for Super‐Resolution Microscopy

ChemBioChem, Volume 27, Issue 18, 28 September 2026.
Nanorulers serve as essential calibration standards to validate optical super‐resolution microscopy down to the Ångström scale. Complementary DNA‐, protein‐, and virus‐based scaffolds provide unique strategies to benchmark spatial resolution, evaluate quantitative labeling efficiency, and mini‐mize linkage errors.
