Spheroid Cell Aggregation Enhanced by Enzyme‐Free Ultrasound‐Detached Cells

Advanced Biology, EarlyView.
This study demonstrates that ultrasound‐based, enzyme‐free cell detachment accelerates spheroid formation by preserving surface proteins, reducing variability, and enhancing cell aggregation. Comparable engraftment and improved spatial organization in co‐cultured spheroids are observed.

Antimicrobial Titanium–Copper Alloys: The Role of Microstructure in Arc‐Melted Compositions

Advanced Engineering Materials, EarlyView.
Copper‐containing titanium alloys show promise in combating orthopedic implant infections. This study explores the influence of heat treatment on Ti‐11.5Cu and Ti‐33Cu alloys, revealing that larger Ti2Cu precipitates (≈5 μm) enhance antimicrobial efficacy through increased surface contact. Results suggest contact sterilization is the primary mechanism,
