Acoustofluidic Patterning for Improved Microtissue Histology

Advanced NanoBiomed Research, EarlyView.
Microtissue histology is widely used to characterize microtissue phenotype and morphology. However, conventional microtissue histology workflows are inefficient and time‐consuming. This work introduces a novel embedding technique that uses acoustofluidics to improve the efficiency of microtissue histology and reduce the time required for data analysis.

Magnetic Supraparticles as Identifiers in Single‐Layer Lithium‐Ion Battery Pouch Cells

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
As an alternative to externally applied optical identifiers, magnetic supraparticles (SPs) can be used for contactless identification of lithium‐ion battery pouch cells via magnetic particle spectroscopy. This study validated the integration and detection of magnetic markers in three model scenarios.
