Biomimetic Carbon‐Based Nanomaterials: From Design Strategies to Next‐Generation Biosensing and Theranostic Applications

Small, EarlyView.
This review summarizes biomimetic design strategies for carbon‐based nanomaterials, including graphene oxide, carbon dots, and nanotubes, highlighting their tunable physicochemical properties for advanced biosensing and theranostic systems. Defined approaches such as DNA templating, peptide‐assisted assembly, and fluorescence switching are discussed ...

Functional and structural mimics of superoxide dismutase enzymes [PDF]

, 2008
Superoxide dismutase (SOD) enzymes form important defence line in living organisms. Through a dismutation reaction they transform the highly reactive superoxide radical ion to oxygen and hydrogen peroxide.

Rapid and Precise Determination of Zero-Field Splittings by Terahertz Time-Domain Electron Paramagnetic Resonance Spectroscopy

, 2017
Zero-field splitting (ZFS) parameters are fundamentally tied to the geometries of metal ion complexes. Despite their critical importance for understanding the magnetism and spectroscopy of metal complexes, they are not routinely available through general

High-resolution electrochemical STM of redox metalloproteins [PDF]

, 2017
Electrochemical studies of redox active metalloproteins have become an increasingly fruitful area of study in recent years, particularly with the single-molecule resolution capability of electrochemical scanning tunnelling microscopy (EC-STM) which ...

Uranyl Binding to Proteins and Structural-Functional Impacts

Biomolecules, 2020
The widespread use of uranium for civilian purposes causes a worldwide concern of its threat to human health due to the long-lived radioactivity of uranium and the high toxicity of uranyl ion (UO22+).

In Vitro Hemocompatibility of the BiVACOR Total Artificial Heart in Continuous and Pulsatile Flow

Artificial Organs, EarlyView.
BiVACOR's total artificial heart generates remarkably similar hemocompatibility when operated with a pulse or during continuous flow. Under both conditions, hemolysis and von Willebrand Factor multimers were similar to a commercial reference device after 6 h in vitro evaluation.

Probing a Complex of Cytochromecand Cardiolipin by Magnetic Circular Dichroism Spectroscopy: Implications for the Initial Events in Apoptosis [PDF]

, 2011
Oxidation of cardiolipin (CL) by its complex with cytochrome c (cyt c) plays a crucial role in triggering apoptosis. Through a combination of magnetic circular dichroism spectroscopy and potentiometric titrations, we show that both the ferric and ferrous

Cryptococcus neoformans Iron-Sulfur Protein Biogenesis Machinery Is a Novel Layer of Protection against Cu Stress

mBio, 2017
Copper (Cu) ions serve as catalytic cofactors to drive key biochemical processes, and yet Cu levels that exceed cellular homeostatic control capacity are toxic. The underlying mechanisms for Cu toxicity are poorly understood.

CPOP1 is a key enzyme required for nodule microenvironment control and successful symbiotic nitrogen fixation in Lotus japonicus

Journal of Integrative Plant Biology, EarlyView.
The enzyme coproporphyrinogen III oxidase plastid related 1 (CPOP1) creates a low‐oxygen nodule environment for nitrogen fixation within nodules of Lotus japonicus. CPOP1 makes heme, which helps control oxygen, and acts in infected cells; its knockout raises oxygen levels, suppresses nitrogen‐fixing enzyme activity, and halts nitrogen fixation ...
