Dynamic Nanoindentation Analysis using Generalized Maxwell Model for Viscoelastic Materials Characterization

Yuya P.A., Patel N.G., Clarkson University, US

Nanoindentation has become a very useful tool for materials properties characterization at nanoscale. The Kelvin-Voigt (two-parameter) solid has been used as the conventional model for the tip-sample forces for viscoelastic contact where the sample stiffness [...]

Self-Assembly of Fluorescent Silica (glass) Beads

Kievesky Ya., Sokolov I., Clarkson University, US

We report self-assembly of fluorescent silica (glass) bids. The bids are a few microns glass nanoporous particles which contain florescent dyes imbedded in the pores. The pores are self-closed, so the dye does not leak [...]

Fluorescent Silica Beads for Detection of Cervical Cancer

Iyer S., Kievesky Ya., Woodworth C.D., Sokolov I., Clarkson University, US

We present the use of self-assembled fluorescent silica (glass) bids for detection of cervical cancer. The cells from three different individuals (3 normal and 3 tumor) were tested for affinity by using the bids, a [...]

Loss of Elasticity of Ageing Epithelial Cells, and Its Possible Reversal

Sokolov I., Woodworth C.D., Clarkson University, US

We investigated human epithelial cells of different age in-vitro by means of the atomic force microscopy. We found that older cells are considerably (~2-10 times) more rigid that younger cells. This helps to explain why [...]
