Artificial Cell Catalysts for Biotransformation: Design Principles and Process Integration

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Artificial cell catalysts are emerging as programmable biocatalytic platforms for sustainable molecular conversion. By reconstituting enzymes and functional modules within synthetic compartments, they combine the selectivity of biological catalysis with the design flexibility of synthetic materials.

Multimodal Imaging of Live Cells and Tumor Spheroids by a G‐Quadruplex DNA Selective Ru(II)Polypyridyl Probe

Chemistry – A European Journal, EarlyView.
Harnessing the light‑switch properties of Ru‑PDC3, we demonstrate that it binds to G‑quadruplex DNA within the nuclei of living cells where it can act as a probe for real‑time imaging or at higher concentrations/illumination it can act as photosensitizer inducing phototoxicity.

Polyphenolic Platform Ameliorated Sanshool for Skin Photoprotection

Advanced Science
Natural evolution has nurtured a series of active molecules that play vital roles in physiological systems, but their further applications have been severely limited by rapid deactivation, short cycle time, and potential toxicity after isolation.

Purification, Fluorescent Labeling, and Detyrosination of Mammalian Cell Tubulin for Biochemical Assays

Cytoskeleton, EarlyView.
ABSTRACT Microtubules play essential roles in numerous cellular processes. All microtubules are built from the protein tubulin, yet individual microtubules can differ spatially and temporally due to their tubulin isotype composition and post‐translational modifications (PTMs).

Sustainable plant‐leaf‐derived carbon dots with deep‐red emission enable 1‐min photodynamic therapy of tumors

FlexMat, EarlyView.
In this study, plant‐derived carbon dots (CDs) were prepared using natural plant leaves as raw materials through solvothermal method. These CDs retain the porphyrin structure from chlorophyll and can simultaneously generate I and II types of reactive oxygen species. A 660 nm laser irradiation for only 1 min can achieve efficient photodynamic anti‐tumor
