High-Intensity Focused Ultrasound in Interventricular Septal Myocardial Ablation.

International heart journal, 2022
High-intensity focused ultrasound (HIFU) can cause necrotic damage in deep tissues through thermal ablation and cavitation, without significant damage to the surrounding tissues. High blood perfusion of heart affects the energy deposition. This study aimed to evaluate the effect of cooling of coronary blood flow for HIFU ablation.Continuous and pulsed ...

Multifunctional Microstructured Surfaces by Microcontact Printing of Reactive Microgels

Advanced Functional Materials, EarlyView.
Reactive poly(N‐vinylcaprolactam‐co‐glycidyl methacrylate) microgels are used as functional inks to create surface‐grafted arrays on glass via microcontact printing. The patterns (10–50 µm widths and spacings) enable stable binding and post‐functionalization with dyes and peptides.
