Poly(methyl methacrylate) with Oleic Acid as an Efficient Candida albicans Biofilm Repellent

Poly(methyl methacrylate) (PMMA), widely used in dentistry, is unfortunately a suitable substrate for Candida (C.) albicans colonization and biofilm formation. The key step for biofilm formation is C. albicans ability to transit from yeast to hypha (filame ...

Controlling structural and magnetic properties of IONPs by aqueous synthesis for improved hyperthermia

Heinrich Hofmann, Alla Arakcheeva, Marijana Mionic Ebersold, Débora Bonvin

Iron oxide nanoparticles (IONPs) were synthesized by a novel aqueous synthesis route which combines co-precipitation (CP) and hydrothermal (HT) treatment, termed CP + HT, and compared with IONPs obtained by the standard CP method. Properties of both types ...

Protein Corona: Impact of Lymph Versus Blood in a Complex In Vitro Environment

Heinrich Hofmann, Ulrich Aschauer, Marc Moniatte, Diego Chiappe, Marijana Mionic Ebersold, Duncan Thomas Lindsay Alexander, Débora Bonvin

In biological environments, the surface of nanoparticles (NPs) are modified by protein corona (PC) that determines their biological behavior. Unfortunately, in vitro tests still give different PC than in vivo tests causing in vitro-in vivo discrepancy; hen ...

Versatility of Pyridoxal Phosphate as a Coating of Iron Oxide Nanoparticles

Heinrich Hofmann, Ulrich Aschauer, Marijana Mionic Ebersold, Débora Bonvin, Josefina Adriana Maria Bastiaansen

Pyridoxal 5'-phosphate (PLP) is the most important cofactor of vitamin B-6-dependent enzymes, which catalyses a wide range of essential body functions (e.g., metabolism) that could be exploited to specifically target highly metabolic cells, such as tumour ...

Folic acid on iron oxide nanoparticles: platform with high potential for simultaneous targeting, MRI detection and hyperthermia treatment of lymph node metastases of prostate cancer

Heinrich Hofmann, Marijana Mionic Ebersold, Débora Bonvin, Josefina Adriana Maria Bastiaansen

The overexpression of the folate receptor in most cancers has been widely exploited to specifically deliver folic acid (FA) coupled nanomedicines to tumors. However, complex coupling chemistry is often used to bind FA to the nanoparticles. Furthermore, ver ...

Assessment of nanoparticles’ safety: corrected absorbance-based toxicity test

Heinrich Hofmann, Marijana Mionic Ebersold, Débora Bonvin

We developed a method to correct absorbance-based toxicity tests to remove the influence of the deposited dose of nano-particles. As a model of absorbance-based toxicity tests, we chose the frequently used MTS test. The corrected cell viabilities obtained ...

Chelating agents as coating molecules for iron oxide nanoparticles

Heinrich Hofmann, Marijana Mionic Ebersold, Débora Bonvin, Josefina Adriana Maria Bastiaansen

Due to their high chemical affinity towards metal ions, chelating agents (CAs) have been used for decades for water purification, but also for protection against metal intoxication and in nanomedicine as linking molecules at the surface of nanoparticles. H ...

Methods of protein corona isolation for magnetic nanoparticles

Heinrich Hofmann, Marc Moniatte, Diego Chiappe, Marijana Mionic Ebersold, Débora Bonvin

Nanoparticles (NPs) in contact with a biological environment get covered by proteins and some are loosely bound and some are tightly bound. The latter form a hard protein corona (HPC) which is known to determine their biological behavior. Therefore, in ord ...

Optimisation of aqueous synthesis of iron oxide nanoparticles for biomedical applications

Heinrich Hofmann, Marijana Mionic Ebersold, Débora Bonvin

Iron oxide nanoparticles (IONPs) were prepared via aqueous synthesis which combines alkaline co-precipitation (CP) of ferric and ferrous precursors with mild hydrothermal (HT) treatment without cupping agents (CA). In this novel synthesis route, CP + HT, w ...

A toolbox of oligopeptide-modified polymers for tailored elastomers

Joël Cugnoni, Véronique Michaud, Emmanuel Croisier, Marijana Mionic Ebersold, Holger Frauenrath, Su Liang, Ruben Anton Snellings, Thomas Schweizer

Biomaterials are constructed from limited sets of building blocks but exhibit extraordinary and versatile properties, because hierarchical structure formation lets them employ identical supramolecular motifs for different purposes. Here we exert a similar ...
