一般描述

The nanoHA products are small-molecular weight hyaluronic acid oligomers prepared by chemoenzymatic synthesis using immobilized enzymes. The name of each nanoHA indicates the number of monosaccharide units in the oligomer. The reducing end contains N-acetyl-D-glucosamine.

应用

NanoHA has been used in a study to assess the nanomechanical properties of electrospun composite scaffolds. It has also been used in a study to investigate the influence of crystallite size of nanophased hydroxyapatite on fibronectin and osteonectin adsorption and on osteoblast adhesion and morphology.

其他说明

nanoHA7 is a heptasaccharide containing three hyaluronan disaccharide subunits (GlcNAcβ4GlcAβ3GlcNAcβ4GlcAβ3GlcNAcβ4GlcAβ3GlcNAcβ4).
To gain a comprehensive understanding of our extensive range of Oligosaccharides for your research, we encourage you to visit our Carbohydrates Category page.

外形

Supplied lyophilized as the ammonium and/or sodium salt.

分析说明

Sold on the basis of carbohydrate as determined by carbazole assay.

Fibrous nanocomposite scaffolds were electrospun from dispersions of hydroxyapatite nanoparticles (nanoHA) in polycaprolactone (PCL) with varying nanoHA contents (from 0% to 50% by weight). Such scaffolds were produced to mimic the nano-features of the extracellular matrix (ECM) for natural bone

The characteristic topographical features (crystallite dimensions, surface morphology and roughness) of bioceramics may influence the adsorption of proteins relevant to bone regeneration. This work aims at analyzing the influence of two distinct nanophased hydroxyapatite (HA) ceramics, HA725 and HA1000 on
Staphylococcus aureus and Staphylococcus epidermidis adhesion to nanohydroxyapatite in the presence of model proteins
