  • Title: Biomolecule and nanoparticle transfer on patterned and heterogeneously wetted superhydrophobic silicon nanowire surfaces.
    Author: Piret G, Coffinier Y, Roux C, Melnyk O, Boukherroub R.
    Journal: Langmuir; 2008 Mar 04; 24(5):1670-2. PubMed ID: 18251564.
    Abstract:
    We report on the use of patterned superhydrophobic silicon nanowire surfaces for the efficient, selective transfer of biological molecules and nanoparticles. Superhydrophilic patterns are prepared on superhydrophobic silicon nanowire surfaces using standard optical lithography. The resulting water-repellent surface allows material transfer and physisorption to the superhydrophilic islands upon exposure to an aqueous solution containing peptides, proteins, or nanoparticles.
