Nano‐Topography Enhanced Topological‐Cell‐Analysis in Radiation‐Therapy

open access: yesAdvanced Healthcare Materials, EarlyView.
Radiotherapy, a treatment that implies exposition of cells to radiation, offers promise to treat cancer. Here, it is hypothesized that the nanoscale details of a scaffold can amplify the response of cells to radiation, measured through topological variables, providing ways to assess the efficacy of Radiotherapy treatment.

A short note on nowhere smooth critical points of polyconvex functionals in arbitrary dimension [PDF]

open access: yesarXiv
For any $M, n \geq 2$ and any open set $\Omega \subset \mathbb{R}^n$ we find a smooth, strongly polyconvex function $F\colon \mathbb{R}^{M\times n}\to \mathbb{R}$ and a Lipschitz map $u\colon \mathbb{R}^n \to \mathbb{R}^M$ that is a weak local minimizer of the energy \[ \int_{\Omega} F(Du). \] but with nowhere continuous partial derivatives.

Development of Itaconate Polymers Microparticles for Intracellular Regulation of Pro‐Inflammatory Macrophage Activation

open access: yesAdvanced Healthcare Materials, EarlyView.
This study develops itaconate‐based polymer microparticles (IA‐MPs) for macrophage‐targeted intracellular delivery, overcoming the limitations of traditional itaconate administration. IA‐MPs achieve controlled release through phagocytosis, reducing pro‐inflammatory cytokine expression and reprogramming macrophage metabolism toward glycolysis.

Hydrogel‐Impregnated Robust Interlocking Nano Connector (HiRINC) for Noninvasive Anti‐Migration of Esophageal Stent

open access: yesAdvanced Materials, EarlyView.
The development of hydrogel‐impregnated robust interlocking nano connector (HiRINC) aims to address stent migration by improving tissue adhesion and reducing mechanical mismatch in self‐expandable metallic stents (SEMSs). The network‐like porous layer of HiRINC enhances adhesion and energy dissipation, demonstrates through ex vivo and in vivo tests ...

Engineering Magnetotactic Bacteria as Medical Microrobots

open access: yesAdvanced Materials, EarlyView.
Magnetotactic bacteria (MTB) are living microorganisms that produce magnetosomes for navigation using the Earth's geomagnetic field. Their built‐in magnetic components, along with their intrinsic and/or modified biological functions, make them one of the most promising platforms for making future living and programmable microrobots.
