Complex self-assembly of reverse poly(butylene oxide)-poly(ethylene oxide)-poly(butylene oxide) triblock copolymers with long hydrophobic and extremely lengthy hydrophilic blocks
(2014)
Amphiphilic block copolymers have emerged during last years as a fascinating substrate material to develop micellar nanocontainers able to solubilize, protect, transport, and release under external or internal stimuli ...
Protein- and polysaccharide-based particles used for Pickering emulsion stabilisation
(2021-10-01)
A few protein- and polysaccharide-based particles can function as effective stabilisers in multi-phase food systems. Combining both polymer-based particles and tailoring the wettability of colloidal systems result in ...
Graft copolymers based on Poly(2-(dimethylamino)ethyl methacrylate) and Poly(ethyleneimine): synthesis and evaluation as vectors for DNA transfection
(Bogotá - Ciencias - Doctorado en Ciencias - QuímicaDepartamento de QuímicaUniversidad Nacional de Colombia - Sede Bogotá, 2020-02-14)
The first chapter reviews the most important aspects of the polymeric vectors used in gene therapy. This type of therapy involves the introduction of genetic material into specific cells to treat certain diseases, using ...
Lactosylated poly(ethylene oxide)–poly(propylene oxide) block copolymers for potential active targeting: synthesis and physicochemical and self-aggregation characterization
(Springer, 2013-01-12)
Aiming to develop polymeric self-assembly nanocarriers with potential applications in active drug targeting to the liver, linear and branched poly(ethylene oxide)- poly(propylene oxide) (PEO-PPO) amphiphiles were conjugated ...
Síntesis de copolímeros dibloque biodegradables conjugados con biomoléculas como plataforma de administración de fármacos
(Bogotá - Ciencias - Maestría en Ciencias - QuímicaDepartamento de QuímicaUniversidad Nacional de Colombia - Sede Bogotá, 2020-02-14)
En el presente trabajo de investigación se sintetizó una biblioteca de materiales basados en copolímeros en bloque anfifílicos de composiciones variables empleando monómeros biocompatibles y altamente biodegradables de ...
Complex self-assembly of reverse poly(butylene oxide)-poly(ethylene oxide)-poly(butylene oxide) triblock copolymers with long hydrophobic and extremely lengthy hydrophilic blocks
(2008)
This is a report of the "Health Policy and Programs Evaluative Research for Social Change" Ibero-American Symposium held in Guadalajara, Mexico November 1-3, 2006. Attendees represented eight countries, and were associated ...
Obtenção de nanopartículas de PMMAbPDMAEMA para sistemas de liberação controlada de moléculas bioativas
(Universidade Federal de São Paulo (UNIFESP), 2018-06-28)
The combination of PMMA, a polymer soluble in organic solvents, and with the watersoluble
PDMAEMA, generates an amphiphilic copolymer with pHdependent
properties and tendency to form micelles. The aim of this work is to ...
Hydrogels based on modified chitosan, 1 - Synthesis and swelling behavior of poly(acrylic acid) grafted chitosan
(WILEY-V C H VERLAG GMBH, 2000-06-20)
A large number of carboxylic groups were introduced onto chitosan by grafting with poly(acrylic acid) as an efficient way of modification. The reactions were carried out in a homogeneous aqueous phase by using potassium ...
