Oligonucleotide/poly(l-lysine) complexes attachment on poly(styrene/maleic acid) and poly(styrene/maleic anhydride polymeric surfaces
The immobilization efficiency of the complexes of oligonucleotide/poly(L-lysine) onto Poly(Styrene/Maleic Acid), PSMA, and Poly(Styrene/Maleic Anhydride), PSMAA, has been investigated using X-ray photoelectron spectroscopy and atomic force microscopy (AFM) in conjugation with fluorescence-based measurements of DNA attachment. A mono-molecularly thin layer of either electrostatically or covalent...
متن کاملMultivalent mannose-displaying nanoparticles constructed from poly{styrene-co-[(maleic anhydride)-alt-styrene]}.
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 their broad utility for modulating protein-c...
متن کاملControlled Release of Damascone from Poly(styrene-co-maleic anhydride)-based Bioconjugates in Functional Perfumery
Poly(styrene-co-maleic anhydride)s were modified with poly(propylene oxide (PO)-co-ethylene oxide (EO)) side chains (Jeffamine) with different EO/PO molar ratios, varying between 0.11 and 3.60. These copolymers were then further functionalized with a β-mercapto ketone of δ-damascone. The obtained poly(maleic acid monoamide)-based β-mercapto ketones were then studied as delivery systems for the ...
متن کاملMorphologies and Thermal Variability of Patterned Polymer Films with Poly(styrene-co-maleic anhydride)
Patterned films of poly(styrene-co-maleic anhydride) copolymers were deposited by dip-coating from acetone solutions. A qualitative study of the film morphologies shows the formation of polymer spheres with smaller diameters at higher amounts of maleic anhydride (MA), and long-fibrous features at higher molecular weights. Upon heating, the films progressively re-assemble with shortand long-fibr...
متن کاملpH-responsive poly(styrene-alt-maleic anhydride) alkylamide copolymers for intracellular drug delivery.
Many macromolecular therapeutics such as peptides, proteins, antisense oligodeoxynucleotides (ASODN), and short interfering RNA (siRNA) are active only in the cytoplasm or nucleus of targeted cells. Endocytosis is the primary route for cellular uptake of these molecules, which results in their accumulation in the endosomal-lysosomal trafficking pathway and loss of therapeutic activity. In this ...
