Spatial Control of Light‐Responsive Proteins and Optogenetics Within Hydrogels via Volumetric Bioprinting

Advanced Materials, EarlyView.
Spatiotemporal control over cell behavior within bioprinted constructs remains a key challenge in biofabrication. Volumetric bioprinting using multi‐wavelength light sources permits to activate light‐sensitive intracellular proteins as well as optogenetic gene and protein expression circuits in bioprinted cells, in addition to enabling fast printing of

Fe-mediated DOM components drive effective arsenic immobilization in tea plantation soils: Mechanisms and quantitative insights

Ecotoxicology and Environmental Safety
In iron (Fe)-rich tea plantation environments, the composition and behaviour of dissolved organic matter (DOM) differ markedly from those observed in other land use systems. Despite its importance, research on DOM in tea plantation soils remains limited,

Fluorescent dissolved organic matter in the dark ocean

, 2012
A dissolved organic matter (DOM) fraction absorbs ultraviolet and visible radiation that partially also emits fluorescence when irradiated with ultraviolet light. To identify the most relevant fluorophores present in deep waters, 429 excitation-emission matrixes (EEMs) from the bathypelagic layer of the Atlantic, Indian and Pacific oceans were recorded

Fluorescence Analysis for Measurement of Dissolved Organic Matter in Environmental Water

Journal of Japan Society on Water Environment, 2004
A fluorescence analysis method, which focuses on the fluorescence intensity of fulvic-like organic matter measured at λex320nm/λem430nm, was applied to evaluate the characteristics of dissolved organic matter (DOM) in environmental waters. The duplicated analyses of a clean river water sample showed that this method was more sensitive by one order of ...
