Adsorption of doxorubicin on poly(methyl methacrylate)-chitosan-heparin-coated activated carbon beads.

Jianjun Miao et al.

Langmuir : the ACS journal of surfaces and colloids, 28(9), 4396-4403 (2012-02-09)

Extracorporeal filter cartridges, filled with an activated carbon bead (ACB) adsorbent, have been used for removal of overdosed cancer drugs from the blood. Coatings on adsorbent matrices, poly(methyl methacrylate) (PMMA)/activated carbon bead and PMMA/chitosan/heparin/ACB composites, were tested to improve their

Mathematical modeling of gallic acid release from chitosan films with grape seed extract and carvacrol.

Javiera F Rubilar et al.

International journal of biological macromolecules, 104(Pt A), 197-203 (2017-06-08)

Controlled release of antimicrobial and antioxidant compounds from packaging films is of utmost importance for extending the shelf-life of perishable foods. This study focused on the mathematical modeling of gallic acid release into an aqueous medium from three chitosan films

Exogenous mineralization of hard tissues using photo-absorptive minerals and femto-second lasers; the case of dental enamel.

A D Anastasiou et al.

Acta biomaterialia, 71, 86-95 (2018-02-21)

A radical new methodology for the exogenous mineralization of hard tissues is demonstrated in the context of laser-biomaterials interaction. The proposed approach is based on the use of femtosecond pulsed lasers (fs) and Fe3+-doped calcium phosphate minerals (specifically in this

A quantitative method for the high throughput screening for the soil adhesion properties of plant and microbial polysaccharides and exudates.

Jumana Akhtar et al.

Plant and soil, 428(1), 57-65 (2018-01-01)

Understanding the structures and functions of carbon-based molecules in soils is an important goal in the context of soils as an ecosystem function of immense importance. Polysaccharides are implicated in maintaining soil aggregate status but have not been extensively dissected

Characterization and Optimization of Chitosan-Coated Polybutylcyanoacrylate Nanoparticles for the Transfection-Guided Neural Differentiation of Mouse Induced Pluripotent Stem Cells.

Martin Hsiu-Chu Lin et al.

International journal of molecular sciences, 22(16) (2021-08-28)

Gene transfection is a valuable tool for analyzing gene regulation and function, and providing an avenue for the genetic engineering of cells for therapeutic purposes. Though efficient, the potential concerns over viral vectors for gene transfection has led to research
