Hydrophobic Interaction and its Small Molecule effect

Protein stabilization has a crucial rule sustaining biological functionality, disease prevention, and pharmaceutical formulation stabilization, and yet its stabilization mechanism by small molecules such as amino acids is not fully understood. In this work ...

Magnetoplasmonic gold nanorods for the sensitive and label-free detection of glutathione

Ting Mao

This work exploits the magneto-optical activity of gold nanorods for the detection of sub-micromolar concentrations of glutathione using magnetic circular dichroism spectroscopy. Modulations of the magnetoplasmonic response of nanorods serve as the basis o ...

Cryogenic electron tomography to determine thermodynamic quantities for nanoparticle dispersions

Francesco Stellacci, Davide Demurtas, Quy Ong Khac, Xufeng Xu, Francesca Olgiati, Ting Mao, Paulo Henrique Jacob Silva, Anna Murello

Here we present a method to extract thermodynamic quantities for nanoparticle dispersions in solvents. The method is based on the study of tomograms obtained from cryogenic electron tomography (cryoET). The approach is demonstrated for gold nanoparticles ( ...

Experimental Method to Distinguish between a Solution and a Suspension

Francesco Stellacci, Quy Ong Khac, Xufeng Xu, Ting Mao, Paulo Henrique Jacob Silva

Dispersion of objects in a fluid phase can be classified as solutions (Gibbs free energy of mixing, Delta G(mix) < 0) or suspensions (Delta G(mix) > 0) depending on their thermodynamic stability. Small objects tend to form solutions, larger ones suspension ...

Monovalent ion-mediated charge-charge interactions drive aggregation of surface-functionalized gold nanoparticles

Francesco Stellacci, Quy Ong Khac, Francesca Olgiati, Ting Mao

Monolayer-protected metal nanoparticles (NPs) are not only promising materials with a wide range of potential industrial and biological applications, but they are also a powerful tool to investigate the behaviour of matter at nanoscopic scales, including t ...
