Preparation and characterization of PEG-coated silica nanoparticles for oral insulin delivery
(Elsevier B.V., 2014-10-01)
The present study reports the production and characterization of PEG-coated silica nanoparticles (SiNP-PEG) containing insulin for oral administration. High (PEG 20,000) and low (PEG 6000) PEG molecular weights were used ...
Poly(ethylene glycol) decorated poly(methylmethacrylate) nanoparticles for protein adsorption
(ELSEVIER SCIENCE BV, 2011)
Poly(ethylene glycol) decorated poly( methyl methacrylate) particles were synthesized by means of emulsion polymerization using poly(ethylene glycol) sorbitan monolaurate (Tween-20) as surfactant. PMMA/PEG particles presented ...
Avaliação da influência de polietilenoglicol (PEG) na hidrólise enzimática de fibra de coco verde pré-tratada com ácido fosfórico
(Universidade Federal do Rio Grande do NorteBrasilUFRNEngenharia QuímicaEngenharia Química, 2021-12-01)
Global population growth, the advance of industrialization, the growing scarcity of fossil energy sources and the need for sustainable means of development are some of the main motivations for the search for renewable ...
Understanding the impact of crosslinked PCL/ PEG/GelMA electrospun nanofibers on bactericidal activity
(2018-12-01)
Herein, we report the design of electrospun ultrathin fibers based on the combination of three different polymers polycaprolactone (PCL), polyethylene glycol (PEG), and gelatin methacryloyl (GelMA), and their potential ...
Ação da mangaba (Hancornia speciosa) adsorvida em polietilenoglicol (PEG) sobre células do câncer de mama (MCF-7)
(Universidade Federal de Mato GrossoBrasilInstituto de Ciências Exatas e da Terra (ICET) – AraguaiaUFMT CUA - AraguaiaPrograma de Pós-Graduação em Ciência de Materiais, 2018-05-04)
The action of biomolecules in the human organism can be limited by two factors: diffusion
speed and period of degradation. The adsorption of these biomolecules in polyethylene glycol
(PEG) based microspheres allows to ...
Efeitos de nanodoses de Bário adsorvidos a microesferas de polietilenoglicol (PEG) sobre cocultura de células mononucleares do sangue humano e linhagens de células de câncer de mama (MCF-7)
(Universidade Federal de Mato GrossoBrasilInstituto de Ciências Exatas e da Terra (ICET) – AraguaiaUFMT CUA - AraguaiaPrograma de Pós-Graduação em Ciência de Materiais, 2017-06-27)
In recent decades due to the increasing number of diseases related to heavy metals, there has
been great interest in the biological effects of these compounds. Among these heavy metals,
Barium (Ba) is highly toxic because ...
