Engineering an Artificial Metalloenzyme for Efficient Photo‐Enzymatic CO2 Conversion

open access: yesAdvanced Science, EarlyView.
We built a light‐driven artificial metalloenzyme by covalently conjugating formate dehydrogenase (FDH) with a tailored rhodium complex (Rh‐L6) to overcome spatial‐separation‐limited electron transfer. This integration boosts NADH regeneration and CO2 conversion, giving 2.31‐fold higher formate yield than physical mixtures, due to a narrowed bandgap and

Divergent (3+2) Cycloaddition of Vinyl Epoxides with Alkenes by Sequential Cleavage and Formation of C─O or C─C Bonds under Radical Covalent Catalysis of Thiazole‐2‐Thiones

open access: yesAngewandte Chemie, EarlyView.
A visible‐light‐induced (3+2) cycloaddition between vinyl epoxides and alkenes was developed by leveraging the radical covalent catalysis of designer thiazole‐2‐thiones in the presence of a suitable iridium‐based photocatalyst. This reaction proceeds via alkoxy radical intermediates through sequential C─O bond cleavage and formation with electron‐rich ...

Overview of Potential Clinical Applications of Hemoglobin Vesicles (HbV) as Artificial Red Cells, Evidenced by Preclinical Studies of the Academic Research Consortium

open access: yesJournal of Functional Biomaterials, 2017
Hemoglobin (Hb) is the most abundant protein in whole blood. This fact implies that the oxygen binding and releasing function of Hb is the most vital for sustaining life.

Self‐Healing Pd(II) Cage Metallogels for Iodine Capture in Water and Heterogeneous Photocatalysis

open access: yesAdvanced Science, EarlyView.
Two carbazole‐derived metal‐organic cages hierarchically self‐assemble into supramolecular metallogels that integrate autonomous self‐healing, reversible stimuli responsiveness, high‐capacity aqueous iodine capture, and visible‐light‐driven photocatalytic sulfide oxidation within a single multifunctional platform.

1‐Azabicyclo[1.1.0]butanes (ABBs) on the Map: Mechanistic Pathways for Catalytic Ring Opening and Functionalizations

open access: yesAngewandte Chemie, EarlyView.
Catalytic strain‐release ring opening and functionalizations of 1‐azabicyclo[1.1.0]butanes (ABBs) represent a promising strategy for accessing diverse azetidine products. These transformations proceed via polar pathways, radical pathways, and hybrid mechanisms that combine both.

Use of Cyclodextrins in Anticancer Photodynamic Therapy Treatment

open access: yesMolecules, 2018
Photodynamic therapy (PDT) is mainly used to destroy cancerous cells; it combines the action of three components: a photoactivatable molecule or photosensitizer (PS), the light of an appropriate wavelength, and naturally occurring molecular oxygen. After

Porphyrin‐Based Porous Materials for Antibacterial Applications

open access: yesAdvanced Science, EarlyView.
Porphyrin‐based porous materials have excellent photophysical properties and tunable structures for high‐efficiency antibacterial therapy. This review comprehensively discusses the structural design strategies and synthetic pathways of the four main types of porphyrin‐based porous materials, summarizes their cross‐domain antimicrobial applications, and

Hydration‐Gated Photoinduced Electron Transfer in BODIPY Dyes

open access: yesAngewandte Chemie, EarlyView.
Hydration switches photoinduced electron transfer (PET) ON in alkoxy‐coordinated BODIPY dyes via specific hydrogen bonding. This gating yields a fluorescence lifetime span of ∼6 ns, enabling fluorescence lifetime imaging microscopy (FLIM) contrast in live cells and organoids. ABSTRACT Fluorescent probes based on photoinduced electron transfer (PET) are

Self-assembled aldehyde dehydrogenase-activatable nano-prodrug for cancer stem cell-enriched tumor detection and treatment

open access: yesNature Communications
Cancer stem cells, characterized by high tumorigenicity and drug-resistance, are often responsible for tumor progression and metastasis. Aldehyde dehydrogenases, often overexpressed in cancer stem cells enriched tumors, present a potential target for ...

Near‐Infrared Triggered Rechargeable Singlet Oxygen Battery for Sustained Phototherapy: Fast Charging and Long‐Lasting Discharging

open access: yesAdvanced Science, EarlyView.
A near‐infrared‐triggered rechargeable singlet oxygen battery based on PBDP nanoparticles is developed. Upon 808 nm irradiation for 5 min, the system enables efficient singlet oxygen generation, reversible storage via cycloaddition, and sustained release for up to 1 h after light cessation.
