A minimalistic cyclic ice-binding peptide from phage display

Harm-Anton Klok, Luciano Andres Abriata, Matthew Gibson, Xudong Kong, Corey Alfred Stevens

Developing molecules that emulate the properties of naturally occurring ice-binding proteins (IBPs) is a daunting challenge. Rather than relying on the (limited) existing structure–property relationships that have been established for IBPs, here we report ...

Impact of polymer-modified gold nanoparticles on brain endothelial cells: exclusion of endoplasmic reticulum stress as a potential risk factor

Harm-Anton Klok, Matthew Gibson

A library of polymer-coated gold nanoparticles (AuNPs) differing in size and surface modifications was examined for uptake and induction of cellular stress responses in the endoplasmic reticulum (ER stress) in human brain endothelial cells (hCMEC/D3). ER s ...

Selective detection of epimeric pentose saccharides at physiological pH using a fluorescent receptor

Matthew Gibson, Joao Pedro De Almeida Neres, Elizabeth Fullam

Epimerisation between ribofuranose and arabinofuranose sugars is crucial in several biosynthetic pathways, but is typically challenging to monitor. Here, we have screened for fluorescent boronic acids that can be used as molecular probes for the specific d ...

Personalising speech-to-speech translation: Unsupervised cross-lingual speaker adaptation for HMM-based speech synthesis

John David Scott Dines, Hui Liang, Lakshmi Babu Saheer, Matthew Gibson, Simon King

In this paper we present results of unsupervised cross-lingual speaker adaptation applied to text-to-speech synthesis. The application of our research is the personalisation of speech-to-speech translation in which we employ a HMM statistical framework for ...

Fast three-dimensional imaging of gold nanoparticles in living cells with photothermal optical lock-in Optical Coherence Microscopy

Theo Lasser, Christian Santschi, Martin Villiger, Christophe Pache, Arno Pino Bouwens, Corinne Berclaz, Noelia Laura Bocchio, Matthew Gibson, Joan Goulley

We introduce photothermal optical lock-in Optical Coherence Microscopy (poli-OCM), a volumetric imaging technique, which combines the depth sectioning of OCM with the high sensitivity of photothermal microscopy while maintaining the fast acquisition speed ...

Size- and Coating-Dependent Uptake of Polymer-Coated Gold Nanoparticles in Primary Human Dermal Microvascular Endothelial Cells

Harm-Anton Klok, Matthew Gibson

A library-orientated approach is used to gain understanding of the interactions of well-defined nanoparticles with primary human endothelial cells, which are a key component of the vasculature. Fifteen sequentially modified gold nanoparticles (AuNPs) based ...

Side-Chain Peptide-Synthetic Polymer Conjugates via Tandem "Ester-Amide/Thiol-Ene" Post-Polymerization Modification of Poly(pentafluorophenyl methacrylate) Obtained Using ATRP

Harm-Anton Klok, Maarten Danial, Matthew Gibson

Herein the concept of tandem postpolymerization modification as a versatile route to synthesize well-defined, highly functionalized polymers is introduced. Poly(pentafluorophenyl methacrylate) obtained by atom transfer radical polymerization was first modi ...

Sequentially Modified, Polymer-Stabilized Gold Nanoparticle Libraries: Convergent Synthesis and Aggregation Behavior

Harm-Anton Klok, Maarten Danial, Matthew Gibson

This manuscript describes a versatile, yet experimentally facile, method for producing libraries of polymer coated (core-shell type) gold nanoparticles. The synthetic principle relies on two, sequential postmodification reactions, which ensures homogeneity ...

Size-Dependent LCST Transitions of Polymer-Coated Gold Nanoparticles: Cooperative Aggregation and Surface Assembly

Harm-Anton Klok, Dusko Paripovic, Matthew Gibson

Nanoparticles working together. Thermoresponsive polymer-coated nanoparticles are shown to display size dependent, cooperative, lower critical solution temperature behavior. This is exploited to direct the assembly of appropriate nanoparticles onto complem ...

Experimentally Facile Controlled Polymerization of N-Carboxyan hydrides (NCAs), Including O-Benzyl-L-threonine NCA

Matthew Gibson

It is demonstrated here that three different alpha-amino N-carboxyanhydrides (NCAs), including for the first time O-benzyl-L-threonine NCA, can be polymerized in a controlled/"living" fashion without the need for transition metal catalysts or complex custo ...
