Enhancing Magnetic Hyperthermia at the Cell Membrane by Anchoring 92R‐Functionalized Magnetic Nanoparticles to Low‐Endocytic CCR9 Surface Receptors

open access: yesAdvanced Healthcare Materials, EarlyView.
We present a strategy to enhance magnetic hyperthermia therapy by modulating nanoparticle–cell interactions. Antibody‐functionalized magnetic nanoparticles targeting the low‐internalizing CCR9 receptor enable spatially controlled membrane anchoring, reducing aggregation and maximizing heat generation under alternating magnetic fields.

Living Materials Approach for In Situ Bio‐Polymers Production Using Bacillus Paralicheniformis in Microneedles

open access: yesAdvanced Healthcare Materials, EarlyView.
Dissolvable microneedle (MN) device containing Bacillus paralicheniformis. The polymeric matrix encapsulates and protects the bacteria, preserving their viability while enabling in situ production and release of γ‐polyglutamic acid. The bacteria are delivered into the skin via 500 µm‐long microneedles, and remain detectable on the skin 24 h post ...
