From RNA to DNA: How Cargo Identity Reprograms Lipid Nanoparticle Architecture and Function

open access: yesAdvanced Healthcare Materials, EarlyView.
The evolution of lipid nanoparticles (LNPs) spans from RNA‐LNPs, used in mRNA vaccines, to DNA‐LNPs, ideal for gene therapies. Emerging bionano architectures, decorated with DNA and plasma proteins, pave the way for advanced DNA‐based therapies that are more stable, targeted, and customizable.

Biomimetic Copper Nanoparticles Coated with ACE2‐Overexpressing Membranes for Selective SARS‐CoV‐2 Neutralization and Disinfection

open access: yesAdvanced Healthcare Materials, EarlyView.
By fusing ACE2‐overexpressing membrane‐integrated liposome (MIL) with copper nanoparticles, the biomimetic Cu@MIL nanostructures were created that directly hijack the SARS‐CoV‐2 entry pathway. These particles combine potent virus‐targeting precision with intrinsic antiviral activity, achieving rapid neutralization and disinfection.

In Situ Synthesis of Covalent Organic Frameworks Inside Cells for Triggering Ferroptosis and Immunotherapy

open access: yesAdvanced Materials, EarlyView.
We have developed an intracellular crystalline polymerization strategy involving acid‐catalyzed imine condensation to synthesize COFs in lysosomes. The generation of COFs in lysosomes damages their integrity, activates iron species, and induces immunogenic ferroptosis, thereby enhancing antitumor immunotherapy.

Electrically Readable Lateral Flow Assay Using Organic Transistors for Diagnostic Applications

open access: yesAdvanced Materials, EarlyView.
Electrolyte‐gated organic field‐effect transistors (EGOFETs) are integrated with lateral flow (LF) paper fluidics to create a reusable, portable, and low‐cost point‐of‐care (PoC) diagnostic test. The devices are validated for Human Immunoglobulin G detection, achieving high sensitivity (0.1 fm), selectivity, and reproducibility with rapid results in 20–

Asymmetric Bi and S Single Atoms Over Porous Single‐Crystal TiO2 for Efficient CO2 Photoreduction to Acetic Acid

open access: yesAdvanced Materials, EarlyView.
Photocatalytic CO2 to acetic acid is achieved over triadic synergy among asymmetric Bi–O4, S–O2 and 3D porous single‐crystal TiO2, harnessed by a selective extraction process. Particularly, the Bi sites lower the energy barrier for CHO* and C─C coupling, and the structure of S─O regulates Bi─O and Ti─O as a strong Lewis base site ((SO2–BiO4)δ−) to ...
