Impact of Surface Functionalization on NV Quantum Properties: Implications for Biosensing with Fluorescent Nanodiamonds

open access: yesAdvanced Functional Materials, EarlyView.
Fluorescent nanodiamonds (fNDs) have emerged as an invaluable quantum sensing platform for biological and biochemical systems. This paper investigates the influence of common surface functionalization strategies for bioconjugation on the quantum properties of nitrogen vacancy (NV) centers in nanodiamonds.

Modulation of TRP Channel Activity by Hydroxylation and Its Therapeutic Potential

open access: yesPharmaceuticals, 2017
Two transient receptor potential (TRP) channels—TRPA1 and TRPV3—are post-translationally hydroxylated, resulting in oxygen-dependent regulation of channel activity.

Preparation and Modification of Activated Carbon for the Removal of Pharmaceutical Compounds via Adsorption and Photodegradation Processes: A Comparative Study

open access: yesApplied Sciences, 2023
In the present research, the removal of pharmaceutical contaminants based on atenolol (AT) and propranolol (PR) using modified activated carbon (AC) in a liquid solution was studied. Two methods, adsorption and photodegradation, were used to eliminate AT

Regioselective Biocatalytic Hydroxylation of Fatty Acids by Cytochrome P450s

open access: yesCatalysis Letters, 2018
Cytochrome P450 enzymes catalyze a broad set of C–H activation reactions, the most prominent being hydroxylation. This review provides an overview of the regioselectivity (CH3-terminal, in-chain, and carboxylate-terminal) and the optical purity of the ...

Living Liquid Metal Composites Embedded with Electrogenic Endospores for Next‐Generation Bioelectronics

open access: yesAdvanced Functional Materials, EarlyView.
A new class of living liquid metal composites is introduced, embedding Bacillus subtilis endospores into eutectic gallium–indium (EGaIn). The spores enhance droplet coalescence, strengthen interfacial conductivity, and provide on‐demand electrogenic functionality after germination. The composites exhibit high conductivity, self‐healing, patternability,

Proline hydroxylation in collagen supports integrin binding by two distinct mechanisms

open access: yesJournal of Biological Chemistry, 2018
Collagens are the most abundant extracellular matrix proteins in vertebrates and have a characteristic triple-helix structure. Hydroxylation of proline residues is critical for helix stability, and diminished prolyl hydroxylase activity causes wide ...

Insigths into the tribochemistry of silicon-doped carbon based films by ab initio analysis of water/surface interactions

open access: yes, 2015
Diamond and diamond-like carbon (DLC) are used as coating materials for numerous applications, ranging from biomedicine to tribology. Recently, it has been shown that the hydrophilicity of the carbon films can be enhanced by silicon doping, which highly ...

Metabolism and toxicity of two new benzodiazepine-type antileishmanial agents in hepatocytes and macrophages [PDF]

open access: yes, 2007
With increasing reports of resistance of Leishmania to antimonials (Thakur et al., 2004) and other traditional antileishmanial drugs, the need for the discovery of new antileishmanial agents is rising.
