Dissimilar Deformation of Fluid- and Gel-Phase Liposomes upon Multivalent Interaction with Cell Membrane Mimics Revealed Using Dual-Wavelength Surface Plasmon Resonance

Publication year: 2022
Authors: Norling K. a, Sjöberg M. a, Bally M b., Zhdanov V.P. a,c , Parveen N.* a, Höök F* a.
Published in: Langmuir 2022 38 (8), 2550-2560

The mechanical properties of biological nanoparticles play a crucial role in their interaction with the cellular membrane, in particular for cellular uptake. This has significant implications for the design of pharmaceutical carrier particles. In this context, liposomes have become increasingly popular, among other reasons due to their customizability and easily varied physicochemical properties. With currently…

Adhesion and Structural Changes of PEGylated Lipid Nanocarriers on Silica Surfaces

Publication year: 2021
Authors: Grad P. 1, Edwards K. 1, Hernández V.A. 2
Published in: Physchem, 2021, Vol. 1(2), p. 133-151

PEGylated lipid nanoparticles have a continuously expanding range of applications, particularly within pharmaceutical areas. Hereby, it is shown with the help of the Quartz Crystal Microbalance with Dissipation monitoring (QCM-D) and other surface sensitive techniques that, at room temperature, PEGylated liposomes and lipodisks adhere strongly to silica surfaces resulting in the displacement of the hydration…

Surface Plasmon Resonance Monitoring of Mono-Rhamnolipid Interaction with Phospholipid-Based Liposomes

Publication year: 2021
Authors: Belkilani M. 1,2.3, Shokouhi M. 4, Farre C. 1, Chevalier Y. 1, Minot S. 1, Bessueille F. 1, Abdelghani A. 3, Jaffrezic-Renault N. 1, Chaix C. 1
Published in: Langmuir, 2021, Vol. 37 (26), p. 7975–7985

The interactions of mono-rhamnolipids (mono-RLs) with model membranes were investigated through a biomimetic approach using phospholipid-based liposomes immobilized on a gold substrate and also by the multiparametric surface plasmon resonance (MP-SPR) technique. Biotinylated liposomes were bound onto an SPR gold chip surface coated with a streptavidin layer. The resulting MP-SPR signal proved the efficient binding…

Non-labelled surface sensitive techniques as platforms for pharmaceutical nanotechnology research

Publication year: 2013
Authors: Huamin Liang, 2013
Published in: Doctoral dissertation (article-based)

Insufficient delivery of drugs to the target sites like tumors and cells has been a barrier for achieving satisfying therapeutic effects in many diseases. Distribution and exposure of drugs to normal and healthy tissues may enhance the possibility of side effects and toxicity in vivo. Nanoparticle (NP) drug delivery systems have been developed to enable…

Fluid dynamics modeling for synchronizing surface plasmon resonance and quartz crystal microbalance as tools for biomolecular and targeted drug delivery studies

Publication year: 2012
Authors: Tapani Viitala (a); Huamin Liang (a); Mayur Gupta (a), (b); Thomas Zwinger (c); Marjo Yliperttula (a); Alex Bunker (d); (e); ⇑
Published in: Journal of Colloid and Interface Science, Vol. 378 (2012), p. 251–259

We have used computational fluid dynamics modeling (CFD) to synchronize the flow conditions in the flow channels of two complementary surface-sensitive characterization techniques: surface plasmon resonance (SPR) and quartz crystal microbalance (QCM). Since the footprint of the flow channels of the two devices is specified by their function, the flow behavior can only be varied…

Real-Time Label-Free Monitoring of Drug- or Nanoparticle-Cell Interactions

Publication year: 2012
Authors: Tapani Viitala, Niko Granqvist, Huamin Liang, Marjo Yliperttula
Published in: Newsletter of the Controlled Release Society, 2012, Vol. 29, No. 6, p. 14-16

Efficient drug delivery is one of the major challenges in modern pharmaceutical research. There is a constant need for developing new formulation strategies for new drug delivery systems because new chemical entities tend to have low solubility, and biotechnology drugs (e.g., DNA, oligonucleotides, antibodies, and proteins) permeate poorly to the target sites, limiting or even…
