“…The deposition time was adjusted to get the desired thickness of gold. 27 Thin ZnO-Au nanostructures were obtained: the Au layer was deposited on the substrate and then coated with a ZnO layer. The thickness of ZnO was 50 nm and was kept constant for all depositions.…”

We have explored the potential of using gold nanoparticles (Au-NPs) in optical and bare-eye discrimination of (a) proteins (such as bovine serum albumin and lysozyme), (b) homo-polynucleotides (such as poly-adenylic acid, polycytidylic acid, poly-uridylic acid and poly-inosinic acid), and (c) long chain DNA (from salmon, herring and thym). Such biomacromolecules can be detected and discriminated due to their ability to prevent the formation of blue aggregates from red (non-aggregated) citrate capped Au-NPs on addition of NaCl. The effect of these biomacromolecules on the aggregation was investigated by colorimetry and UV-vis spectrometry. The results show that the two proteins can be differentiated by colorimetry, and also salmon ssDNA and dsDNA. The AuNPs can also discriminate the dsDNAs of salmon and herring. We conclude that the use of Au-NPs represent a viable candidate to future methods of DNA analysis on the basis of visual testing, particularly in the area of food analysis.

Abstract:Electrospinning is a versatile technique to produce micron or nano sized fibers using synthetic or bio polymers. The unique structural characteristic of the electrospun mats (ESM) which mimics extracellular matrix (ECM) found influential in regenerative tissue engineering application. ESM with different morphologies or ESM functionalizing with specific growth factors creates a favorable microenvironment for the stem cell attachment, proliferation and differentiation. Fiber size, alignment and mechanical properties affect also the cell adhesion and gene expression. Hence, the effect of ESM physical properties on stem cell differentiation for neural, bone, cartilage, ocular and heart tissue regeneration will be reviewed and summarized. Electrospun fibers having high surface area to volume ratio present several advantages for drug/biomolecule delivery. Indeed, controlling the release of drugs/biomolecules is essential for sustained delivery application. Various possibilities to control the release of hydrophilic or hydrophobic drug from the ESM and different electrospinning methods such as emulsion electrospinning and coaxial electrospinning for drug/biomolecule loading are summarized in this review.
