  • Interfacial forces across ionic liquid solutions : effect of ion concentration and water domains 

    Adibnia, Vahid; Mirbagheri, Marziye; Latreille, Pierre-Luc; De Crescenzo, Gregory; Rochefort, Dominic; Banquy, Xavier (American Chemical Society, 2019-07-23)
    Using the surface force apparatus (SFA), the interaction forces between mica surfaces across ionic liquid (IL) solutions are studied. The IL solution, 1-hexyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide in propylene carbonate solvent, is used ...

  • Mechanistic insights into the directed assembly of hydrogel blocks mediated by polyelectrolytes or microgels 

    Hanauer, Nicolas; Latreille, Pierre-Luc; Banquy, Xavier (2017-04-18)
    In this study, we report the directed assembly of hydrogel blocks mediated by electrostatic interactions. We compared two different assembly mechanisms, one mediated by microgel particles and another mediated by direct interaction between ...

  • A multi-modal miniature surface forces apparatus (µSFA) for interfacial science measurements 

    Kristiansen, Kai; Donaldson, Stephen; Berkson, Zachariah J.; Scott, Jeffrey; Su, Rongxin; Banquy, Xavier; Dong Woog, Lee; de Aguiar, Hilton B.; McGraw, Joshua; Degen, George D.; Israelachvili, Jacob N. (American Chemical Society, 2019-07-30)
    Advances in the research of intermolecular and surface interactions result from the development of new and improved measurement techniques and combinations of existing techniques. Here, we present a new miniature version of the Surface Force Apparatus ...

  • Plasmon-free polymeric nanowrinkled substrates for surface-enhanced raman spectroscopy of two-dimensional materials 

    Mirbagheri, Marziye; Kaur, Jasneet; Pham, Hoang Vu; Adibnia, Vahid; Zarrin, Hadis; Banquy, Xavier; Hwang, Dae Kun (American Chemical Society, 2020-12-21)
    We report plasmon-free polymeric nanowrinkled substrates for surface-enhanced Raman spectroscopy (SERS). Our simple, rapid, and cost-effective fabrication method involves depositing a poly(ethylene glycol)diacrylate (PEGDA) prepolymer solution droplet ...

  • Synergy between zwitterionic polymers and hyaluronic acid enhances antifouling performance 

    Xia, Yinqiang; Adibnia, Vahid; Shan, Cancan; Huang, Renliang; Qi, Wei; He, Zhimin; Xie, Guojun; Olszewski, Mateusz; De Crescenzo, Gregory; Matyjaszewski, Krzysztof; Banquy, Xavier; Su, Rongxin (American Chemical Society, 2019-09-03)
    Challenges associated with nonspecific adsorption of proteins on sensor surfaces have steered the development of novel antifouling materials and strategies. Inspired by human synovial fluid composition and structure, we designed synergistic antifouling ...

  • Unified scaling of the structure and loading of nanoparticles formed via diffusion-limited coalescence 

    Rode García, Teresita; García Ac, Araceli; Lalloz, Augustine; Lacasse, Francois-Xavier; Hildgen, Patrice; Rabanel, Jean-Michel; Banquy, Xavier (American Chemical Society, 2018-04-30)
    The present study establishes the scaling laws describing the structure of spherical nanoparticles formed by diffusion-limited coalescence. We produced drug-loaded nanoparticles from a poly(ethylene glycol)-poly(d,l-lactic acid) diblock polymer (PEG-b-PLA) ...
