Journal ArticleDOI
Ultrastable Iron Oxide Nanoparticle Colloidal Suspensions Using Dispersants with Catechol-Derived Anchor Groups
TL;DR: Catechol-derivative anchor groups which possess irreversible binding affinity to iron oxide and thus can optimally disperse superparamagnetic nanoparticles under physiologic conditions are found, which leads to ultrastable iron oxide nanoparticles.
Journal ArticleDOI
Stabilization and functionalization of iron oxide nanoparticles for biomedical applications
TL;DR: This review details how dispersants have been optimized to gain close control over iron oxide NP stability, size and functionalities by independently considering the influences of anchors and the attached sterically repulsive polymer brushes.
Journal ArticleDOI
Triggered release from liposomes through magnetic actuation of iron oxide nanoparticle containing membranes
Esther Amstad,Joachim Kohlbrecher,Elisabeth Müller,Thomas Schweizer,Marcus Textor,Erik Reimhult,Erik Reimhult +6 more
TL;DR: Stealth liposomes comprising self-assembled superparamagnetic iron oxide nanoparticles individually stabilized with palmityl-nitroDOPA incorporated in the lipid membrane are demonstrated to be able to control timing and dose of repeatedly released cargo from such vesicles.
Journal ArticleDOI
Colloidal stabilization of nanoparticles in concentrated suspensions.
TL;DR: This study synthesized dispersants with a molecular architecture that enables better control over the particle adlayer thickness that facilitates the fabrication of a wide range of products and intermediates in materials technology, cosmetics, pharmacy, and in all areas where concentrated nanoparticle suspensions are required.
Journal ArticleDOI
25th Anniversary Article: Double Emulsion Templated Solid Microcapsules: Mechanics And Controlled Release
Sujit S. Datta,Alireza Abbaspourrad,Esther Amstad,Jing Fan,Shin-Hyun Kim,Mark B. Romanowsky,Ho Cheung Shum,Bingjie Sun,Andrew S. Utada,Maike Windbergs,Shaobing Zhou,David A. Weitz +11 more
TL;DR: How droplet microfluidics can be used to fabricate solid-shelled microcapsules having precisely controlled release behavior is described and used to tune the compositions and geometrical characteristics of the microcapsule with exceptional precision.
