Chitosan as a Bioadhesive Agent Between Porphyrins and Phospholipids in a Biomembrane Model
(AMER SCIENTIFIC PUBLISHERS, 2011)
Porphyrins are currently used in photodynamic therapy as photosensitizers. In this paper we studied the interaction of two charged porphyrins, 5, 10, 15, 20-mesotetrakis(N-metyl-4-pyridyl) porphyrin, (TMPyP/chloride salt) ...
Hydrophobic silver nanoparticles interacting with phospholipids and stratum corneum mimic membranes in Langmuir monolayers
(Academic Press Inc Elsevier Science, 2019-05)
The interaction of hydrophobic silver nanoparticles with different phospholipids and stratum corneum mimic (SCM) membranes is studied in Langmuir monolayers. Thus, silver nanoparticles coated with oleic acid (AgNP-OA) were ...
Combination of cyclic voltammetry and single-particle Brownian dynamics methodology to evaluate the fluidity of phospholipid monolayers at polarized liquid/liquid interfaces
(Pergamon-Elsevier Science Ltd, 2018-08)
The present work shows, for the first time, the use of single-particle Brownian dynamics methodology, followed by optical microscopy, coupled with electrochemistry techniques to evaluate the fluidity of phospholipid films ...
Interactions of gold nanoparticles with a phospholipid monolayer membrane on mercury
(American Chemical Society, 2014-06)
It is demonstrated that a compact monolayer of 1,2-dioleoyl-sn-glycero-3-phosphocholine<br />adsorbed to a hanging mercury drop electrode can serve as a simple electrochemical<br />model system to study biomembrane penetration ...
Porphyrin-phospholipid interaction and ring metallation depending on the phospholipid polar head type
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2010)
The interaction between a hydrophobically modified 5,10,15,20-tetrakis(4-N-tetradecyl-pyridyl) porphyrin and three phospholipids: two negatively charged, DMPA (the sodium salt of dimyristoyl-sn-glycero-phosphatidyl acid) ...
Interaction of horseradish peroxidase with Langmuir monolayers of phospholipids
(ELSEVIER SCIENCE BV, 2008)
The method employed to incorporate guest molecules onto phospholipid Langmuir monolayers plays an important role in the interaction between the monolayer and the guest molecules. In this paper, we show that for the interaction ...
Nicotinamide and picolinamide in phospholipid monolayers
(John Wiley & Sons Inc., 2012-09)
Molecular dynamics simulations have been performed to investigate the interactions between nicotinamide (NA) and picolinamide (PA) with Langmuir monolayers of zwitterionic lipids: dimyristoylphosphatidylcholine (DMPC) and ...
Distinctive Interactions of Oleic Acid Covered Magnetic Nanoparticles with Saturated and Unsaturated Phospholipids in Langmuir Monolayers
(American Chemical Society, 2014-04)
The growing number of innovations in nanomedicine and nanobiotechnology are posing new challenges in understanding the full spectrum of interactions between nanomateriales and biomolecules at nano-biointerfaces. Although ...
Study of the diclofenac/phospholipid interactions with liposomes and monolayers
(Elsevier B.V., 2004-07-01)
The interaction of diclofenae sodium (SD) with soya phosphatidylcholine (SPC) has been studied with floating Langmuir monolayers and liposomes. SD was either introduced into the subphase of SPC monolayers or co-spread with ...
Alkyl esters of l-ascorbic acid: Stability, surface behaviour and interaction with phospholipid monolayers
(Academic Press Inc Elsevier Science, 2015-11)
l-ascorbic acid alkyl esters (ASCn) are molecules of pharmaceutical interest for their amphiphilic nature and proposed antioxidant power. In contrast to l-ascorbic acid, ASCn with different acyl chain lengths behaved stably ...
