Responsive Materials

, ,
Continuous advances in polymer chemistry are enabling the synthesis of novel responsive biomaterials. This class of biomaterials are polymers able to undergo significant changes in their properties in response to external stimuli. Depending on their [...]

Fabrication of magnetic bio-Au nanoclusters by using SlaA-layer ghosts of Sulfolobus acidocaldarius as a template

, , , , , ,
We demonstrate that the outermost proteinaceous surface layer SlaA of the thermo acidophilic archaeon Sulfolobus acidocaldarius is an excellent matrix for preparation of bio-Au nanoclusters. The archaeal bio-Au nanoparticles are significantly bigger and possess considerably [...]

Synthesis and characterization of new nanoparticles formed by milk whey proteins submitted to a thermal gelation process

, , , , ,
In this work, nanostructures formed by the two whey proteins (alpha-lactoalbumin and beta-lactoglobulin) were synthesized througha thermal gelation process. The obtained proteic nanoparticles were characterized by using dynamic light scattering, transmission electron microscopy and atomic [...]

Biological effects of PLA-TCP nanocomposites on osteoblastic cells

, , , , , , , , , , , , , ,
Composite substrates are considered as prospective matrix to populate and support cells in the bioengineering field. Synthetic degradable biomaterials, including poly(lactic acid) (PLA) and tricalcium phosphate (TCP), are widely used for matrix scaffold. In present [...]

Synthesis and Characterization of Anti-CD4 monoclonal antibody-conjugated Magnetic Poly (glycidyl methacrylate) Particles and their Application on CD4+ Lymphocyte Separation

, , , , ,
To develop an efficient magnetic system for separation of CD4+ lymphocytes, we design a simple, specific, and cost-effective CD4 separation system without the need for column separation technique. Novel immunomagnetic particles have been prepared for [...]

Characterization of Nanostructural Modifications Introduced into a Model Pectic Homogalacturonan by Esterases or Chemical Saponification and Modeling of Enzyme Mode of Action

, , , , , , ,
Pectin functionality is largely dependent on the ratio of methylesterified/demethylesterified galacturonic acid (GalA) residues present in its polymeric homogalacturonan region (40 – 60 nm in length, 100 – 150 GalA residues) and how the two [...]
