This concise survey delves into the capabilities of atomic force microscopy (AFM) for investigating the DNA/gold interface. It highlights how the precise control of the force applied by AFM enables its use as a nanolithography tool, allowing for localized sample modifications. The interface manipulation is functional to explore the DNA layer...

By using AFM as a nanografting tool, we grafted micrometer-sized DNA platforms into inert alkanethiol SAMs. Tuning the grafting conditions (surface density of grafting lines and scan rate) allowed us to tailor the molecular density of the DNA platforms. Following the nanografting process, AFM was operated in the low perturbative Quantitative...

Porous transition metal oxides are widely studied as biocompatible materials for the development of prosthetic implants. Resurfacing the oxide to improve the antibacterial properties of the material is still an open issue, as infections remain a major cause of implant failure. We investigated the functionalization of porous titanium oxide...
