• of gold nanorods (AuNR) by thiolated cyclodextrin (CD) host molecules. As a result of the complete removal of the precursor capping agent cetyltrimethylammonium bromide (CTAB) by a tetraethylene glycol derivative, competitive binding to the host cavity was prevented, and reversible, light-responsive

Especially gold nanorods (AuNR) are of interest because of their good synthetic availability and their unique optical properties. Due to their anisotropy AuNR possess a transversal SPR (TSPR) band in the visible and

• different bacterial adhesion. Indeed, gold nanorods presented a bacteria detection limit of 0.03 ± 0.01 µg/mL, 80-folds more sensitive than spherical and star shaped AuNPs. This discrepancy has been ascribed to the difference in the relative amount of mannose involved in the NP-bacteria interaction. The

Lactose- and polyethylene glycol (PEG)-functionalized gold nanorods demonstrated similar ability in reducing the interaction with proteins, when compared to
