[Heavy particle radiation therapy].
The characteristics of radiation formed by heavy particles make it a highly useful tool for therapeutic use. Protons, helium nuclei or carbon ions are being successfully employed in radiotherapy installations throughout the world. This article sets out the physical and technological foundations that make these radiation particles suitable for attacking

Particle beams such as protons and heavier ions show an increase in nergy deposition with penetration depth up to a maxi-mum at the end of their range, the so-called Bragg perk. Almost no dose is deposited in normal tissue beyond the Bragg peak. The particle range is determined by the energy of the incoming particles.

Nanodiamond Quantum Sensors for Probing Free Radical Biology
Free radicals play key roles in cellular signaling and disease but remain difficult to measure in living systems. Nanodiamonds (NDs) with nitrogen‐vacancy (NV) centers enable quantum sensing of local magnetic noise via T₁ relaxometry, providing nondestructive radical detection in living cells.

Gold bipyramids can act as efficient plasmonic nanoheaters, but they often reshape during laser heating. This study shows that oxygen nanobubbles drive oxidative etching and that surface ligands control stability. CTAB‐ and citrate‐coated particles blunt and lose optical performance, whereas polystyrene sulfonate preserves shape and heating by ...
