Exploiting Mannuronan C-5 Epimerases in Commercial Alginate Production

Marine Drugs, 2020
Alginates are one of the major polysaccharide constituents of marine brown algae in commercial manufacturing. However, the content and composition of alginates differ according to the distinct parts of these macroalgae and have a direct impact on the ...

A Biochemical Logic Approach to Biomarker-Activated Drug Release [PDF]

J. Mater. Chem. 22, 19709-19717 (2012), 2013
The present study aims at integrating drug-releasing materials with signal-processing biocomputing systems. Enzymes alanine transaminase (ALT) and aspartate transaminase (AST)---biomarkers for liver injury---were logically processed by a biocatalytic cascade realizing Boolean AND gate. Citrate produced in the system was used to trigger a drug-mimicking

Improving The Antioxidant Activity of Sodium Alginate from Sargassum sp. by Thermal Heating and Chemical Methods

Jurnal Kelautan Tropis, 2020
The relationship between molecular structure and bioactivity was evaluated for sodium alginates obtained under different degradation treatment (raw alginates, heat-treated, and chemical-treated) from Sargassum sp. This study was conducted to identify the

Alginate reduces the increased uptake of cholesterol and glucose in overweight male subjects: a pilot study [PDF]

, 2008
Dietary fibers are of particular interest in the prevention and management of obesity and consequent pathologies. Among the proposed mechanisms of action of fiber is the modulation of nutrient uptake from the small intestine.

Towards a better understanding on agglomeration mechanisms and thermodynamic properties of TiO2 nanoparticles interacting with natural organic matter [PDF]

Water Research 80, 139 - 148 (2015), 2015
Interaction between engineered nanoparticles and natural organic matter is investigated by measuring the exchanged heat during binding process with isothermal titration calorimetry. TiO2 anatase nanoparticles and alginate are used as engineered nanoparticles and natural organic matter to get an insight into the thermodynamic association properties and ...

HUVECs-encapsulation via Millimeter-sized Alginate Droplets [PDF]

arXiv, 2023
Droplet microfluidics are a powerful approach for hydrogel cell encapsulations. Much of the field has focused on single-cell encapsulations with pico-nanoliter droplet volumes necessary for single-cell sequencing or high-throughput screening. These small volumes, however, limit the use of hydrogel droplets for tissue engineering or cell therapies.

Strong deformation of ferrofluid-filled elastic alginate capsules in inhomogenous magnetic fields [PDF]

Langmuir 34, 13534-13543 (2018), 2019
We present a new system based on alginate gels for the encapsulation of a ferrofluid drop, which allows us to create millimeter-sized elastic capsules that are highly deformable by inhomogeneous magnetic fields. We use a combination of experimental and theoretical work in order to characterize and quantify the deformation behavior of these ferrofluid ...

Nitrogen sorption as a tool for the characterisation of polysaccharide aerogels [PDF]

, 2011
Supercritically dried aerogels of several polysaccharides (chitin, chitosan, alginate, alginic acid, k- carrageenan, and agar) have been characterised by physisorption ofN2. Surface areas as high as 570m2 g−1 have been measured.
