The Spinning Manny Indexed Overlay System for VMAT total body irradiation
Journal of Applied Clinical Medical Physics, Volume 27, Issue 1, January 2026.Abstract Purpose While modern intensity‐modulated techniques for total body irradiation (TBI) offer superior organ sparing and improved dose coverage compared to conventional TBI, their complexity has limited widespread adoption. Specifically, when treating individuals with Volumetric Modulated Arc Therapy (VMAT‐TBI), a transition between the head ...

Cell Shuttling in Multifunctional Microsized Needles
Small Structures, Volume 7, Issue 1, January 2026.We report the bottom‐up synthesis of microsized needles with high volume to area ratio where cells attach preferentially, being explored as a platform for cell delivery. Microsized platforms are crucial for injectable cell delivery systems acting as cell carriers to improve the delivery and retention efficacy at the injury site.
