Poly(styrene- co -maleic anhydride) nanoparticles as protein carriers

Materials Letters, 2018
Abstract Considering the increasing interest for protein immobilization on nanoparticles, in this work, we demonstrate the preparation of poly(styrene-co-maleic anhydride) (PSMA) nanoparticles and their capability to conjugate the proteolytic enzyme papain.

Reaction effect on the properties of poly(ethylene terephthalate) and poly(styrene- co -maleic anhydride) blends

Polymer, 2000
Poly(ethylene terephthalate) (PET) was blended with polystyrene (PS) and poly(styrene-co-maleic anhydride) (PScMA). The two blend systems were immiscible based on the glass transition temperatures measured by differential scanning calorimetry (DSC). In the case of 70 and 90% PScMA blends, the reaction between ester groups of PET and maleic anhydride ...

Applications of DEPT experiments to the carbon-13 NMR of copolymers: poly(styrene-co-maleic anhydride) and poly(styrene-co-acrylonitrile)

Macromolecules, 1984
The DEPT technique for the generation of CH, CH, and CH C NMR subspectra has enabled the resolution and assignment of broad and overlapping aliphatic resonances in copolymers. For styreneacrylonitrile copolymers, the CH resonances gave dyad fractions that were in agreement with the previously established copolymer structure.

Temperature and pH-responsive properties of poly(styrene-co-maleic anhydride)-grafting poly(oxypropylene)-amines

Journal of Colloid and Interface Science, 2009
A series of temperature- and pH-responsive copolymers were prepared by grafting poly(oxypropylene)-diamines (POP-amine) onto poly(styrene-co-maleic anhydride) (SMA) copolymers. Owing to the presence of poly(oxypropylene)-segments in the pendants and their expressive hydrogen bonding properties, the copolymers exhibited lower critical solution ...

Preparation and Characterization of Poly (Styrene-Co-Maleic Anhydride)-Modified Boron Particles

Journal of Dispersion Science and Technology, 2010
The surface modification of boron powder with poly (styrene-co-maleic anhydride) (SMA) has been achieved through the reactions between the hydroxy groups on the surface of boron and the maleic anhydride groups in SMA. This novel polymerically modified boron was characterized using IR, TGA, TEM, and laser grain size analyzer.

Multivalent mannose-displaying nanoparticles constructed from poly{styrene-co-[(maleic anhydride)-alt-styrene]} [PDF]

Organic & Biomolecular Chemistry, 2009
Micellar mannose nanoparticles were constructed from poly{styrene-co-[(maleic anhydride)-alt-styrene]} with fluorophores or quenchers doped into the hydrophobic inner cores, allowing the direct monitoring of multivalent lectin-glycan interactions. The mannose-displaying nanoparticles bind Con A and sperm surface lectins with high affinity, suggesting ...

Vibration welding of glass-filled poly(styrene-co-maleic anhydride)

Journal of Adhesion Science and Technology, 2001
Vibration welding is used to assess the weldability of 16 wt% glass-filled poly(styrene-comaleic anhydride) (16-GF-SMA). Data are presented on the strengths of butt welds for two specimen thicknesses and T-welds for one specimen thickness. The maximum weld strength of butt joints is shown to be only 35% of the tensile strength of the material. T-joints

Electrospun polystyrene–poly(styrene-co-maleic anhydride) nanofiber as a new aptasensor platform

Biosensors and Bioelectronics, 2012
Here, we report the use of an aptamer-immobilized electrospun polystyrene-poly(styrene-co-maleic anhydride) (PS-PSMA) nanofiber as a new aptasensor platform for protein detection. Two thrombin-binding aptamers (TBA29 and TBA15) were used as a model platform to facilitate efficient detection of thrombin in a sandwich manner.
