Metal–Organic Frameworks for Gaseous Pollutant Management: From Capture to Neutralization and Reutilization

Advanced Functional Materials, EarlyView.
This review maps how MOFs can manage hazardous gases by combining adsorption, neutralization, and reutilization, enabling sustainable air‐pollution control. Covering chemical warfare agent simulants, SO2, NOx, NH3, H2S, and volatile organic compounds, it highlights structure‐guided strategies that boost selectivity, water tolerance, and cycling ...

Development of Lactococcus lactis Biosensors for Detection of Sulfur-Containing Amino Acids

Frontiers in Microbiology, 2020
The sulfur-containing amino acids methionine and cysteine play an important role in food industry. These amino acids are used to confer a sulfur smell or meat-related aroma to food products.

Effective Penetration of the Oxidized Keratin‐Rebonding Materials Into Hair Shafts Based on Charge Conversion

Advanced Healthcare Materials, EarlyView.
We have developed a smart hair‐repair ingredient based on β‐carboxylic acid amide that undergoes negative‐to‐positive charge conversion under mildly acidic conditions. The initial negative charge facilitates deep penetration into the hair fiber, while the subsequent positive charge enables re‐bonding with sulfonate groups in damaged hair keratin.

Enzymatic Synthesis of Amino Acids Endcapped Polycaprolactone: A Green Route Towards Functional Polyesters

Molecules, 2018
ε-caprolactone (CL) has been enzymatically polymerized using α-amino acids based on sulfur (methionine and cysteine) as (co-)initiators and immobilized lipase B of Candida antarctica (CALB) as biocatalyst.

Antioxidant Effects of Sulfur-Containing Amino Acids

Yonsei Medical Journal, 2004
Sulfur is an essential element for the entire biological kingdom because of its incorporation into amino acids, proteins and other biomolecules. Sulfur atoms are also important in the iron-containing flavoenzymes. Unlike humans, plants can use inorganic sulfur to synthesize sulfur-containing amino acids.

A Biomimetic Buffering Hydrogel Scaffold for Long‐Term Culture of Patient‐Derived Tumor Organoids

Advanced Healthcare Materials, EarlyView.
A biomimetic fibrous buffering hydrogel controls the local acidification at the tumoroid/hydrogel interface at the physiologically relevant level over 21‐day culture. The buffering effect promotes cancer cell proliferation in the tumoroids and supports the structural integrity and mechanical properties of the hydrogel scaffold over long‐term tumoroid ...

Nutrilyzer: A Tool for Deciphering Atomic Stoichiometry of Differentially Expressed Paralogous Proteins

Journal of Integrative Bioinformatics, 2012
Organisms try to maintain homeostasis by balanced uptake of nutrients from their environment. From an atomic perspective this means that, for example, carbon:nitrogen:sulfur ratios are kept within given limits.

The compositional and evolutionary logic of metabolism

, 2012
Metabolism displays striking and robust regularities in the forms of modularity and hierarchy, whose composition may be compactly described. This renders metabolic architecture comprehensible as a system, and suggests the order in which layers of that ...

Evaluation of the Dual Impact of Nanotechnologies on Health and Environment Through Alternative Bridging Models

Advanced Healthcare Materials, EarlyView.
This review explores how alternative invertebrate and small‐vertebrate models advance the evaluation of nanomaterials across medicine and environmental science. By bridging cellular and organismal levels, these models enable integrated assessment of toxicity, biodistribution, and therapeutic performance.
