Analysis of αB-crystallin polydispersity in solution through native microfluidic electrophoresisIn this paper, the authors utilise microfluidic diffusional sizing and electrophoresis to characterise the oligomeric states of the chaperone protein alphaB-crystallin.

On-chip label-free protein analysis with downstream electrodes for direct removal of electrolysis productsSaar et al designed and demonstrated a single step lithography approach to fabricate microfluidic devices that can be used to apply high electric fields without the formation of any electrolysis products in the electrophoresis area.

Gradient-free determination of isoelectric points of proteins on chipLapinska et al. using a microfluidic system built in house design a new technique to determine a protein's isoelectric point (pI) based on microfluidic free-flow electrophoresis (μFFE). The approach exploits temporal rather than spatial pH gradients. To demonstrate the effectiveness of this method the pI of 7 different proteins of known pI were tested; β-lactoglobulin, ribonuclease A, ovalbumin, human transferrin, ubiquitin and myoglobin. The paper shows that this method is successful in determining the pI using this new technique without the requirement of generating and maintaining pH gradients which is often challenging for other techniques. The technique requires low voltages and low sample consumption. The paper also shows that using this technique it is possible to estimate the pI values for a wide range of proteins measuring at only two pH values, suggesting that this technique is rapid and accurate on small volume samples.

Putative interaction site for membrane phospholipids controls activation of TRPA1 channel at physiological membrane potentials.Macikova et al use Microfluidic Diffusional Sizing (MDS) along with other techniques to understand the role phosphatidylinositol-4,5-bisphosphate (PIP2) has in the regulation of transient receptor potential ankyrin 1 (TRPA1) channel. The Fluidity One was used to create binding curves of the interactions between two specific peptides (L992-N1008 and T1003-P1034) and model lipid membranes in the presence of PIP2.

Secondary nucleation and elongation occur at different sites on Alzheimer’s amyloid-β aggregatesIn this paper MDS was used to identify two molecular chaperones which suppress secondary nucleation processes and inhibit the elongation of Aβ fibrils seen in Alzheimer's disease.

α-Synuclein-derived lipoparticles in the study of α-Synuclein amyloid fibril formationThis paper probes the interactions of α-synuclein with lipid particles using the Fluidity One and various other methods, to investigate the link between these interactions and α-synuclein aggregation.

Cooperative Assembly of Hsp70 Subdomain ClustersWright et al use Microfluidic Diffusional Sizing to probe the oligomerisation of the SBD641 substrate of human Hsp70. The Fluidity One was employed to verify if the fluorescent label used had an affect on measured hydrodynamic radius during the tests.

Protein Aggregate-Ligand Binding Assays Based on Microfluidic Diffusional SeparationZhang et al again demonstrate the utility of Microfluidic Diffusional Sizing to monitor Nanobody binding to ɑ-synuclein, but this time also use MDS to monitor ɑ-synuclein fibril formation.

Microfluidic diffusion viscometer for rapid analysis of complex solutions.Arosio et al demonstrate the utility of a diffusion viscometer, showing that by including tracer particles and tracking mass transport, the viscosity of complex solutions can be determined using only low quantities of sample material, with a short analysis time and can be integrated into other microfluidic elements on a chip.

Microfluidic diffusion analysis of the sizes and interactions of proteins under native solution conditions.In this paper from Arosio et al microfluidic diffusional sizing (MDS) is used in combination with pre-labelled fluorescent biomolecules to size and quantify proteins in complex mixtures. Initially, MDS is compared to Dynamic Light Scatter (DLS) - and a good correlation is observed for monodispersed solutions.
