Intracellular Drug Delivery Nanocarriers of Glutathione-Responsive Degradable Block Copolymers Having Pendant Disulfide Linkages
17-05-2013 | Behnoush Khorsand; Gabriel Lapointe; Christopher Brett; Jung Kwon Oh, Biomacromolecules, 2013
Self-assembled micelles of amphiphilic block copolymers (ABPs) with stimuli-responsive degradation (SRD) properties have a great promise as nanotherapeutics exhibiting enhanced release of encapsulated therapeutics into targeted cells. Here, thiol-responsive degradable micelles based on a new ...
Covalent Core–Shell Architecture of Hemoglobin and Human Serum Albumin as an Artificial O2 Carrier
16-05-2013 | Daiki Tomita; Takuya Kimura; Hitomi Hosaka; Yuta Daijima; Risa Haruki; Kai Ludwig; Christoph Böttcher; Teruyuki Komatsu, Biomacromolecules, 2013
Covalent core–shell structured protein clusters of hemoglobin (Hb) and human serum albumin (HSA) (HbX-HSAm) (m = 2, 3) with novel physiological properties were generated by linkage of Hb surface lysins to HSA cysteine-34 via an α-succinimidyl-ε-maleimide cross-linker (X: 1 or 2). The ...
Barnacle Cement as Surface Anchor for “Clicking” of Antifouling and Antimicrobial Polymer Brushes on Stainless Steel
16-05-2013 | Wen Jing Yang; Tao Cai; Koon-Gee Neoh; En-Tang Kang; Serena Lay-Ming Teo; Daniel Rittschof, Biomacromolecules, 2013
Barnacle cement (BC) was utilized ‘beneficially’ as a surface anchor on stainless steel (SS) for coupling of functional polymer brushes via “click” reactions in both “grafting-to” and “grafting-from” processes. Ethylene sulfide (ES), propargyl carbonylimidazole (PPC) and azidoethyl ...
Antioxidative Carbohydrate Polymer from Enhydra fluctuans and Its Interaction with Bovine Serum Albumin
16-05-2013 | Debjani Ghosh; Sayani Ray; Kanika Ghosh; Valérie Micard; Udipta R. Chatterjee; Pradyot K. Ghosal; Bimalendu Ray, Biomacromolecules, 2013
Enhydra fluctuans leaves are traditionally sold on Indian markets for various health benefits. However, no phytochemical study on its high molecular weight compound has so far been performed. Chemical, chromatographic, ESI-TOF-MS, and NMR analyses of the water extracted carbohydrate polymer ...
Bioinspired, Calcium-Free Alginate Hydrogels with Tunable Physical and Mechanical Properties and Improved Biocompatibility
15-05-2013 | Changhyun Lee; Jisoo Shin; Jung Seung Lee; Eunkyoung Byun; Ji Hyun Ryu; Soong Ho Um; Dong-Ik Kim; Haeshin Lee; Seung ..., Biomacromolecules, 2013
Alginate hydrogels are for various biomedical applications including tissue engineering, cell therapy, and drug delivery. However, it is not easy to control swelling or viscoelastic and biophysical properties of alginate hydrogels prepared by conventional cross-linking methods (ionic ...
Ionization Behavior of Chitosan and Chitosan–DNA Polyplexes Indicate That Chitosan Has a Similar Capability to Induce a Proton-Sponge Effect as PEI
15-05-2013 | Isabelle Richard; Marc Thibault; Gregory De Crescenzo; Michael D. Buschmann; Marc Lavertu, Biomacromolecules, 2013
Polycations having a high buffering capacity in the endosomal pH range, such as polyethylenimine (PEI), are known to be efficient at delivering nucleic acids by overcoming lysosomal sequestration possibly through the proton sponge effect, although other mechanisms such as membrane disruption ...
Tuning the Structure of Protein Particles and Gels with Calcium or Sodium Ions
15-05-2013 | Tuan Phan-Xuan; Dominique Durand; Taco Nicolai; Laurence Donato; Christophe Schmitt; Lionel Bovetto, Biomacromolecules, 2013
The effect of the addition of NaCl or CaCl2 on the structure of protein particles and gels was investigated in detail for aqueous solutions of the globular milk protein β-lactoglobulin at 40g/L and pH 7.0. When heated in the presence of NaCl or at very low CaCl2 concentrations, the proteins ...
Copolymerization of 2-Methylene-1,3-dioxepane and Glycidyl Methacrylate, a Well-Defined and Efficient Process for Achieving Functionalized Polyesters for Covalent Binding of Bioactive Molecules
15-05-2013 | Jenny Undin; Anna Finne-Wistrand; Ann-Christine Albertsson, Biomacromolecules, 2013
The understanding of cell–material interactions is important for creating personalized implants for tissue engineering. This has resulted in an interest in developing polymers with functional groups with the possibility of controlling the macromolecular surface. We have in a one-pot reaction ...
Biobased Chitosan/Polybenzoxazine Cross-Linked Films: Preparation in Aqueous Media and Synergistic Improvements in Thermal and Mechanical Properties
14-05-2013 | Almahdi A. Alhwaige; Tarek Agag; Hatsuo Ishida; Syed Qutubuddin, Biomacromolecules, 2013
A novel class of polymer blends has been prepared from main-chain-type benzoxazine polymer (MCBP) and chitosan (CTS), a modified biomacromolecule. A water-soluble, main-chain-type benzoxazine polymer, MCBP(BA-tepa), was synthesized from the reaction of bisphenol A (BA), tetraethylenepentamine ...
Efficient Cell and Cell-Sheet Harvesting Based on Smart Surfaces Coated with a Multifunctional and Self-Organizing Elastin-Like Recombinamer
14-05-2013 | María Pierna; Mercedes Santos; Francisco J. Arias; Matilde Alonso; José C. Rodríguez-Cabello, Biomacromolecules, 2013
A wide range of smart surfaces with novel properties relevant for biomedical applications have been developed recently. Herein we focus on thermoresponsive surfaces that switch between cell-adherent and nonadherent states and their applications for cell harvesting. These smart surfaces are ...
