Facile meltPEGylation of flame-made luminescent Tb3+-doped yttrium oxide particles: hemocompatibility, cellular uptake and comparison to silica

23-May-2018 | Kerda Keevend; Guido Panzarasa; Fabian H. L. Starsich; Martin Zeltner; Anastasia Spyrogianni; Elena Tsolaki; Giusepp ..., Chemical Communication, 2018

Flame aerosol technology is a versatile method for scalable synthesis of nanoparticles. Since particles are produced and collected in a dry state, dispersibility and further functionalization could pose hurdles to their biomedical use. We report on a one-pot, scalable and robust procedure for the ...

Compatibility of PEGylated Polymer Nanoparticles with the Biophysical Function of Lung Surfactant

19-Dec-2017 | Moritz Beck-Broichsitter, Langmuir, 2017

To minimize an unwanted interference of colloidal drug delivery vehicles with the biophysical functionality of lung surfactant, the surface of polymer nanoparticles was modified with poly(ethylene glycol) (PEGylation). Plain poly(lactide) nanoparticles provoked a statistically relevant decrease ...

Polyethylene Glycol Based Changes to β-Sheet Protein Conformational and Proteolytic Stability Depend on Conjugation Strategy and Location

09-Oct-2017 | Steven R. E. Draper; Paul B. Lawrence; Wendy M. Billings; Qiang Xiao; Nathaniel P. Brown; Natalie A. Bécar; Derek J. ..., Bioconjugate Chemistry, 2017

The development of chemical strategies for site-specific protein modification now enables researchers to attach polyethylene glycol (PEG) to a protein drug at one or more specific locations (i.e., protein PEGylation). However, aside from avoiding enzyme active sites or protein-binding interfaces, ...
