Direct Surface Modification of the Epidermis Using Mussel‐Inspired Polydopamine with Multiple Anti‐Biofouling Functions

Advanced Healthcare Materials, EarlyView.
Surface modification using mussel‐derived polydopamine (PDA) is a versatile and robust biocompatible strategy that enables direct application to various epidermal surfaces, regardless of their morphological complexity or surface characteristics. The PDA‐coated epidermis exhibits multiple anti‐biofouling functionalities, including antibacterial and anti‐

Tumor Microenvironment‐responsive Nanocatalyst for Targeted Chemodynamic Cancer Therapy

Advanced Healthcare Materials, EarlyView.
An Tumor microenvironment‐responsive nanocatalyst system composed of PLGA‐encapsulated Ca–Fe peroxide and polyarginine enables sustainable Fenton reaction in tumors. Low levels of H2O2 (50–100 µm) initiate the nanoparticle degradation, while polyarginine‐derived nitric oxide accelerates Fe3+ reduction, leading to self‐amplifying •OH generation for ...

A Targeted Redox‐Active Dual‐Action Pt(IV)‐Mn(II) Prodrug Displays Enhanced In Vivo Anticancer Activity

Advanced Healthcare Materials, EarlyView.
A new oxaliplatin‐based Pt(IV) prodrug bearing a Mn(II) superoxide dismutase mimic is synthesized and studied, in vitro and in vivo, in the context of colorectal cancer. Encapsulation of this prodrug in an easy‐to‐implement PEGylated micelle formulation demonstrated the highest in vivo anticancer activity among all the tested conditions, supporting the

Antitumoral Efficacy of AuNRs‐Laden ECFCs In Vitro and In Vivo: Decoding the Heat and Rays Combo Treatment in Breast Cancer and Melanoma Cells

Advanced Healthcare Materials, EarlyView.
Endothelial Colony Forming Cells (ECFCs) acted as cellular cyborgs, stealthily transporting gold nanorods (AuNRs) into tumors to enable targeted near‐infrared (NIR) hyperthermia combined with radiotherapy. This approach triggers ferroptosis in melanoma and inhibits autophagy in breast cancer, revealing a tumor‐specific response to nanomaterial‐assisted
