The GibsonGroup's latest research into the use of biomaterials to increase the availability of donor cells has been published in Angewandte Chemie. Donor cells (e.g blood, bone marrow) are crucial to modern healthcare but due to their short shelf life they must be frozen using organic solvents as 'antifreezes'. The Gibson group has pionnered the use of synthetic polymers which inhibit ice crystal growth and their application to cryopreservation. In this work, a collaboraiton with Prof. Steve Armes at Sheffield, the team used biomimetic block copolymer micelles to provide a hydrated 'matrix' around the cells, which in combination with ice inhibiting polymers enable succesful cryopreservation of red blood cells. This is the first example of a cryopreservation system using entirely synthetic polymer materials, providing control and additional functionality into the system. Post-thawing, the micelles warm up, and become 'worm-like' which enabled the direct formation of a hydrogel, which is of interest for tissue engineering.

The manuscript entitled Control of vesicle membrane permeability with catalytic particles by the BonLab has been selected for the jan-feb 2016 cover of Materials Horizons, a premier scientific journal published by the Royal Society of Chemistry which features first reports of exceptional significance across the breadth of materials research at the cutting-edge interface with chemistry, physics, biology and engineering.

Prof.dr.ir. Stefan Bon, head of the BonLab, says: "We are absolutely delighted that our research has made the cover of Materials Horizons. Rong Chen and especially Ross Jaggers worked very hard in the BonLab to fabricate giant polymer vesicles which have membrane-embedded catalytically active manganese oxide particles, hereby using droplet-based microfluidics. We demonstrate that these colloidal particles can regulate the membrane permeability of the polymersomes upon their exposure to, and catalytic reaction with, small amounts of dissolved hydrogen peroxide. Not only can we trigger complete release whereby the vesicle gets destroyed through membrane rupture by the formed oxygen bubbles as illustrated on the cover, exposure to small amounts of dissolved hydrogen peroxide leads to temporary enhanced release until all hydrogen peroxide is consumed by the catalytic particles after which the membrane permeability restores itself to its passive characteristic value."

More on this can be read on the blog of the BonLab site.

An Angew. Chem. VIP from Lewandowski group investigates the influence of different intermolecular interactions on protein dynamics. The paper presents first ever extensive site-specific relaxation measurements on a large non-crystalline protein-antibody complex in a few nanomole quantities. The study paves the way for direct characterization of dynamics in biologically important but sensitivity-limited samples of proteins within large complexes.

Ordered growth of vanadyl phthalocyanine (VOPc) on an iron phthalocyanine (FePc) monolayer

A recent paper by the GibsonGroup in Chem Commun has been highlighted in the RSC Magazine 'Chemistry World'. The Gibson Group have a research program focussed on mimicking the function of Antifreeze Proteins which are found in Polar fish species. These proteins can slow the rate of ice growth, which has been identified as a challenge in the cryopreservation of donor cells and tissue for transplantation. In this work they showed a facile route to new cryoprotective polymers, using cheap, commodity polymer starting materials. These polymers were shown to have ice growth inhibition activity and to signficantly reduce the ice-induced damage during red blood cell freeze/thaw storage. In a second paper, the group also reported signficantly enhanced cryopreservation using poly(vinyl alcohol).

Józef Lewandowski in collaboration with Lyndon Emsley (EPFL, Lausanne/ENS-Lyon) and Martin Blackledge (IBS, Grenoble) reports in Science on a direct observation of hierarchy of protein and solvent motions in protein conformational energy landscape. The findings of the study employing a series of variable temperature magic angle spinning multinuclear NMR relaxation measurements on a nanocrystalline protein reconcile divergent interpretations from techniques that are individually sensitive to dynamic phenomena occurring on different time scales and at different locations in protein-solvent systems.
