Researchers at the National University of Singapore have developed a high-throughput method to identify gold nanoparticles capable of delivering therapies directly to mitochondria (the energy centres inside cancer cells). By tagging nanoparticles with unique DNA “barcodes”, the team was able to track and compare dozens of designs simultaneously in living tumour models, rapidly identifying those most effective at reaching this critical subcellular target.

The researchers coupled the vehicle-track dynamics model with the UIUC model to provide a comprehensive description of vehicle-induced ballast settlement — encompassing both its full evolution and cumulative dynamic effects. Special emphasis was placed on the influence of sleeper voids.

Researchers in Japan showed that growing Eu-doped GaN on a semipolar GaN plane selectively forms highly efficient Eu luminescent centers while suppressing inefficient Eu clusters. The approach increased room-temperature red emission by 3.6 times, reduced efficiency droop, and points to brighter, wavelength-stable red LEDs for monolithically integrated full-color micro-LED displays using the GaN materials platform.
