Control and Characterization of the Compactness of Single-Chain Nanoparticles

Francesco Stellacci, Luciano Andres Abriata, Lixia Wei, Suiyang Liao

Polymers when self-cross-linked into single-chain nanoparticles bear some resemblance to folded proteins; yet proteins have clear energy landscapes that determine precisely folded structures, while single-chain polymer nanoparticles (SCNPs) have more undef ...

A simple micropreparative gel electrophoresis technique for purification of proteins, nucleic acids, and bioconjugates

Ardemis Anoush Boghossian, Sayyed Hashem Sajjadi, Shang-Jung Wu, Vitalijs Zubkovs

The biochemical and biomedical fields hinge on the ability to effectively separate and purify biological macromolecules. Though this need is largely addressed with a variety of chromatographic and electrophoretic purification techniques, such techniques ar ...

An Instrumented High-Speed Rotor with Embedded Telemetry for The Continuous Spatial Pressure Profile Measurement in Gas Lubricated Bearings: A Proof of Concept

Jürg Alexander Schiffmann, Karim Magdi Zakaria Abdelrahman Shalash

Pressure is one of the constitutional quantities governing the flow field in gas lubricated bearings. Knowledge of the pressure is of principal importance in the fundamental understanding of such bearings and for the calibration of reduced order models. Th ...

On the effect of ligand shell heterogeneity on nanoparticle/protein binding thermodynamics

Francesco Stellacci, Ahmet Bekdemir, Suiyang Liao

Nonspecific protein adhesion to nanoparticle (NP) has been proven to have important implications in nanomedicine. However, there are only a few examples of careful studies relating protein binding thermodynamics to NP physicochemical features. In particula ...

Studies on fluid dynamics of the flow field and gas transfer in orbitally shaken tubes

Florian Maria Wurm, David Hacker, Xiao Shen, Dominique Terry Monteil Jr, Likuan Zhu

Orbitally shaken cylindrical bioreactors [OrbShake bioreactors (OSRs)] without an impeller or sparger are increasingly being used for the suspension cultivation of mammalian cells. Among small volume OSRs, 50-mL tubes with a ventilated cap (OSR50), origina ...

A centrifugation-based physicochemical characterization method for the interaction between proteins and nanoparticles

Francesco Stellacci, Ahmet Bekdemir

Nanomedicine requires in-depth knowledge of nanoparticle-protein interactions. These interactions are studied with methods limited to large or fluorescently labelled nanoparticles as they rely on scattering or fluorescence-correlation signals. Here, we hav ...

A Multilaboratory Comparison of Calibration Accuracy and the Performance of External References in Analytical Ultracentrifugation

Jutta Christine Wandrey, Ahmet Bekdemir, Helmut Coelfen

Analytical ultracentrifugation (AUC) is a first principles based method to determine absolute sedimentation coefficients and buoyant molar masses of macromolecules and their complexes, reporting on their size and shape in free solution. The purpose of this ...
