  • Microgel particles formed from β-lactoglobulin (Blg) are able to stabilize Pickering emulsions, yet their interfacial properties have not been fully characterized. In this study, quartz crystal microbalance with dissipation (QCM-D) was employed to investigate adsorption behavior of Blg microgels on a hydrophobic solid surface. The QCM-D results showed that adsorption efficiency of the microgels was strongly dependent on the particle charge and the ionic strength of the aqueous phase. The adsorption of weakly charged Blg microgels (pH 5.6) was characterized by highly covered particles, producing a relative rigid monolayer at the interface…

  1. Name:The effect of end‐group substitution on surface self‐assembly of peptides
AuthorsAlona Dolid and Meital Reches
JournalJournal of Peptide Science
  • 10.1002/psc.3212
  • Biofouling, the undesirable accumulation of organisms onto surfaces, affects many areas including health, water, and energy. We previously designed a tripeptide that self‐assembles into a coating that prevents biofouling. The peptide comprises three amino acids: DOPA, which allows its adhesion to the surface, and two fluorinated phenylalanine residues that direct its self‐assembly into a coating and acquire it with antifouling properties. This short peptide has an ester group at its C‐terminus. To examine the importance of this end group for the self‐assembly and antifouling properties of the peptide, we synthesized and characterized tripeptides with different end groups (ester, amide, or carboxylic group) …

  1. Name:Exploiting mammalian low-complexity domains for liquid-liquid phase separation-driven underwater adhesive coatings
AuthorsMengkui Cui, Xinyu Wang, Bolin An, Chen Zhang, Xinrui Gui, Ke Li, Yingfeng Li, Peng Ge, Junhu Zhang, Cong Liu and Chao Zhong
JournalScience Advances
  • 10.1126/sciadv.aax3155
  • Many biological materials form via liquid-liquid phase separation (LLPS), followed by maturation into a solid-like state. Here, using a biologically inspired assembly mechanism designed to recapitulate these sequential assemblies, we develop ultrastrong underwater adhesives made from engineered proteins containing mammalian low-complexity (LC) domains. We show that LC domain–mediated LLPS and maturation substantially promotes the wetting, adsorption, priming, and formation of dense, uniform amyloid nanofiber coatings on diverse surfaces (e.g., Teflon), and even penetrating difficult-to-access locations such as the interiors of microfluidic devices…

  1. Name:Supramolecular Presentation of Hyaluronan onto Model Surfaces for Studying the Behavior of Cancer Stem Cells
AuthorsXinqing Pang, Clare O'Malley, João Borges, Muhammad M. Rahman, Dominic W. P. Collis, João F. Mano Ian C. Mackenzie and Helena S. Azevedo
JournalAdvanced Biosystems
  • 10.1002/adbi.201900017
  • The supramolecular presentation of extracellular matrix components on surfaces provides a platform for the investigation and control of cell behavior. Hyaluronan (HA) is one of the main components of the extracellular environment and has been shown to play an important role in different cancers and their progression. However, current methods of HA immobilization often require its chemical modification. Herein, a peptide‐based self‐assembled monolayer (SAM) is used as an anchor to immobilize unmodified HA on a bare gold surface, as demonstrated by the quartz crystal microbalance with dissipation monitoring…

  • Antimicrobial resistance (AMR) has been identified as a major threat to public health worldwide. To ensure appropriate use of existing antibiotics, rapid and reliable tests of AMR are necessary. One of the most common and clinically important forms of bacterial resistance is to β-lactam antibiotics (e.g., penicillin). This resistance is often caused by β-lactamases, which hydrolyze β-lactam drugs, rendering them ineffective. Current methods for detecting these enzymes require either time-consuming growth assays or antibiotic mimics such as nitrocefin …

  • The solubilization of membranes by detergents is critical for many technological applicationsand has become widely used in biochemistry research to induce cell rupture, extract cell constituents,and to purify, reconstitute and crystallize membrane proteins. The thermodynamic detailsof solubilization have been extensively investigated, but the kinetic aspects remain poorlyunderstood. Here we used a combination of single-vesicle Förster resonance energy transfer(svFRET), fluorescence correlation spectroscopy and quartz-crystal microbalance with dissipationmonitoring to access the real-time kinetics and elementary solubilization steps of sub-micronsized vesicles, which are inaccessible by conventional diffraction-limited optical methods…

  1. Name:PPEGMEMA-based cationic copolymers designed for layer-by-layer assembly
AuthorsTao Jiang, Saeed Zajforoushan Moghaddam and Esben Thormann
JournalRSC Advances
  • 10.1039/C9RA05464B
AbstractWe have synthesized three PPEGMEMA-based cationic copolymers with similar amine contents but with systematic variation in the average length of the PEG side chains. The positively charged copolymers were paired with alginate to fabricate layer-by-layer assembled multilayered films. It was demonstrated that the polymeric design, in terms of the systematic variation in the average length of the PEG units, affects the polyelectrolyte multilayer growth mechanism and can be used to tune the structural properties and the water content of the layers…

  • 10.1016/j.compositesb.2019.107399
  • Carboxylated nanofibrillated cellulose (CNFC) has emerged as a promising green dispersant to prepare stable aqueous individual montmorillonite (MMT) suspensions. Nevertheless, its underlying dispersive mechanism remains elusive. Herein, we attempt to unveil the dispersive mechanism of CNFC for individual MMTs in water by characterizing the interfacial interactions between the two components using a quartz crystal microbalance with dissipation monitoring (QCM-D) and an atomic force microscopy (AFM). Both electrostatic repulsion and steric hindrance contribute to the excellent stability of homogeneous individual MMT suspensions, and their individual contributions are dependent upon the dosage of CNFC dispersant…

  • Achieving solute selectivity has always been a goal of membrane development studies. The continuing growth of global consumption of scarce metals by different industries has put a strain on traditional sources of these species. Achieving cation selectivity in membranes, especially among monovalent cations, is a major step in introducing alternative sources for scarce metals such as lithium…

  1. Name:Impact of polyethylene glycol polymers on the physicochemical properties and mucoadhesivity of itraconazole nanoparticles
AuthorsRicardoMachado Cruz, MariaJose Santos-Martinez and LidiaTajber
JournalEuropean Journal of Pharmaceutics and Biopharmaceutics
  • 10.1016/j.ejpb.2019.09.004
  • Itraconazole (ITR) is a broad-spectrum antifungal drug with a very low solubility. In this work, the application of a heat induced evaporative antisolvent nanoprecipitation process yielded disordered nanoparticles (NPs) of ITR. The inclusion of different types of poly(ethylene glycol) (PEG) allowed PEGylation of NPs by adsorption to be achieved. The NP dispersions were composed of monodispersed particles in a nanometric size range (<290 nm) and although PEGylation had no impact on the average particle size, the surface potential was partially neutralised in the modified NPs…

  1. Name:Metal Chelating Polymer Thin Films by Surface-Initiated ROMP and Modification
AuthorsXuanli Deng, Liudmyla Prozorovska and Gannon Kane Jennings
JournalThe Journal of Physical Chemistry C
  • 10.1021/acs.jpcc.9b06410
  • We report the surface initiated ring-opening metathesis polymerization (SiROMP) of hydroxamic-acid containing, metal-chelating polymer thin films. SiROMP of trans-5-norbornene-2,3-dicarbonyl chloride (NBDAC) is introduced as a versatile platform to achieve many functional polymer films via simple exposure of the pNBDAC film to reagents. This modification strategy owes its success to the fast and high-yield reaction of acyl chlorides with alcohols, amines, water, and other molecules…
