Intrinsic Photoactive Star ZnPc–Poly(glutamate) Nanoplatforms for Multimodal Glioblastoma Therapy and Brain‐Targeted Delivery

Advanced Functional Materials, EarlyView.
An intrinsic photoactive star‐shaped zinc phtalocyanine‐poly(L‐glutamic acid) (ZnPc‐PGA) nanoplatform for multimodal glioblastoma (GBM) therapy and brain‐targeted elivery. A ZnPc‐PGA‐based multifunctional theranostic nanocarrier platform enables image‐guided, multimodal GBM therapy. ZnPc‐PGA nanocarriers support the integration of fluorescence imaging,

Chiral Phase Change Nanomaterials

Advanced Functional Materials, EarlyView.
This work demonstrates reversible, non‐volatile phase transitions in chiral Ge2${\rm Ge}_2$Sb2${\rm Sb}_2$Te5${\rm Te}_5$ (GST) nanohelices for high‐speed optical modulation of chirality and dynamic control of the state of polarization (SOP). The chiral nanostructures are fabricated using a highly directional, wafer‐scale physical vapor deposition ...

Bioinspired Mechanically Robust Organic–Inorganic Hybridized Bio‐Adhesives With up to 50% Inorganic Components by Bi‐Continuous Phase Engineering

Advanced Functional Materials, EarlyView.
A robust plant protein adhesive was prepared by fabricating a bi‐continuous organic–inorganic hybrid structure. Compared with traditional organic–inorganic hybrid adhesives, the addition amount of inorganic phase is increased from 0.2%–3.0% to 50%, and the strength and toughness are increased by 6 and 121 times, respectively.

Controlled Engineering of 2D Alkali‐Iron‐Chloride Compounds and Lateral Quantum Heterostructures Within Confined Graphene Nanoreactors

Advanced Functional Materials, EarlyView.
This work presents a programmable atomic engineering strategy for 2D materials using Å‐scale nanoreactors formed by bilayer graphene (BLG) intercalation. A new class of alkali‐iron‐chloride compounds, along with lateral heterostructures composed of monolayer alkali halides and iron chlorides, is revealed.
