Challenges in the Characterisation of Therapeutic Protein Formulations

Ball S., Pothecary M., Clarke P., Murphy C., Malvern Instruments, UK

In recent years, the stability of proteins in solution has attracted significant scientific and commercial interest due to the exponential growth in the use of proteins as biotherapeutic drugs. Since knowledge of formulation stability and [...]

Passive Microrheology : Non Contact Measurement of Viscoelastic Properties of Biopolymers

Tisserand C., Kotzev A., Fleury M., Brunel L., Bru P., Brunel L., Meunier G., Formulaction, FR

This work presents a new technique of the passive microrheology for the study of the microstructure properties of soft materials. Our technology uses Multi Speckle DWS (MS-DWS) set-up in backscattering with a video camera. It [...]

Passive Microrheology : Non Intrusive Measurement of the Emulsions Stability

Tisserand C., Fleury M., Brunel L., Bru P., Brunel L., Meunier G., Formulaction, FR

This work presents a new technique of the passive microrheology for the study of the microstructure properties of soft materials like emulsions. Our technology uses Multi Speckle DWS (MS-DWS) set-up in backscattering with a video [...]

Magnetic nanoparticles with variable size and shape and surface functionality as switchable building blocks for soft nanotechnology

Dietsch H., Malik V., Reufer M., Schurtenberger P., Fribourg Center fro Nanomaterials, FriMat, CH

Alpha-Fe2O3 (hematite) particles can be synthesized by forced hydrolysis of iron salts. The chosen iron salt dissolves and leads to a first crystalline structure called akaganeite (Beta-FeOOH), which, reorganized and combined with more iron precursor [...]

Protein binding to particle surfaces determines intracellular interaction and uptake kinetics

Ehrenberg M., McGrath J.L., University of Rochester, US

People are exposed to nanoparticles in from varying sources and in many ways. The goal of our research is to simplify this diverse problem by establishing a systematic understanding of the properties of particles that [...]
