Journal ArticleDOI
Low viscosity hydrogel of guar gum: preparation and physicochemical characterization.
Pablyana L.R. Cunha,Rondinelle Ribeiro Castro,Francisco Airton Castro Rocha,Regina C.M. de Paula,Judith P.A. Feitosa +4 more
TL;DR: The low viscosity, the small amount of remained glutaraldehyde, and the thermal stability indicates that the guar hydrogel has potential to be applied as biomaterial with specific rheological requirements.
Journal ArticleDOI
Purification of guar gum for biological applications
TL;DR: Commercial guar gum was purified by four different methods and characterized by gel permeation chromatography (GPC), thermogravimetric analysis and the determination of monosaccharides composition, protein and copper content, turbidity, intrinsic viscosity and rheological parameters.
Journal ArticleDOI
Isolation and characterization of galactomannan from Dimorphandra gardneriana Tul. seeds as a potential guar gum substitute
Pablyana L.R. Cunha,Ícaro Gusmão Pinto Vieira,Ângela M.C. Arriaga,R.C.M. de Paula,Judith P.A. Feitosa +4 more
TL;DR: A galactomannan was obtained from mature seeds of Dimorphandra gardneriana Tul., the plant from which rutin is extracted as discussed by the authors, using manual separation of the endosperm, water dissolution, centrifugation and precipitation with ethanol.
Journal ArticleDOI
Sulfated chitosan as tear substitute with no antimicrobial activity.
Natalia da Rocha Pires,Pablyana L.R. Cunha,Jeanny S. Maciel,Alysson L. Angelim,Vania Maria Maciel Melo,Regina C.M. de Paula,Judith P.A. Feitosa +6 more
TL;DR: The derivative with DS 0.67 had a higher solubility, less chain depolymerization, higher yield and better thermal stability in comparison with chitosan-S-0.87, and offered the greatest potential for use in formulations of tear substitutes.
Journal ArticleDOI
Novel and Fast Microwave-Assisted Synthesis of Carbon Quantum Dots from Raw Cashew Gum
Natalia da Rocha Pires,Clara M. W. Santos,Rayane R. Sousa,Regina C.M. de Paula,Pablyana L.R. Cunha,Judith P.A. Feitosa +5 more
TL;DR: Carbon quantum dots (C-dots) with average size of 9 nm were synthesized from an aqueous solution of raw cashew gum (RCG) using a novel and fast microwave-assisted technique which involves two steps as mentioned in this paper.
