Ionically Paired Layer-by-Layer Hydrogels: Water and Polyelectrolyte Uptake Controlled by Deposition Time.

Gels (Basel, Switzerland)

Selin V, Ankner JF, Sukhishvili SA.
PMID: 30674783
Gels. 2018 Jan 11;4(1). doi: 10.3390/gels4010007.

Despite intense recent interest in weakly bound nonlinear ("exponential") multilayers, the underlying structure-property relationships of these films are still poorly understood. This study explores the effect of time used for deposition of individual layers of nonlinearly growing layer-by-layer (LbL)...

ACS Appl Bio Mater. 2019 Sep 16;2(9):3897-3906. doi: 10.1021/acsabm.9b00485. Epub 2019 Aug 28.

In this work, novel sulfo-fluoro polyphosphazenes (PPzs) were synthesized via macromolecular substitution of polydichlorophosphazene utilizing "non-covalent protection" methodology by converting acid functionalities into hydrophobic alkylammonium salts. Resulting PPzs showed excellent solubility in aqueous solutions over a broad pH range...

Selective hydrogen bonding controls temperature response of layer-by-layer upper critical solution temperature micellar assemblies.

Soft matter

Soft Matter. 2021 Mar 04;17(8):2181-2190. doi: 10.1039/d0sm01997f.

This work establishes a correlation between the selectivity of hydrogen-bonding interactions and the functionality of micelle-containing layer-by-layer (LbL) assemblies. Specifically, we explore LbL films formed by assembly of poly(methacrylic acid) (PMAA) and upper critical solution temperature block copolymer micelles...

Hydrogen-Bonded, Mechanically Strong Nanofibers with Tunable Antioxidant Activity.

ACS applied materials & interfaces

Gaikwad A, Hlushko H, Karimineghlani P, Selin V, Sukhishvili SA.
PMID: 32048504
ACS Appl Mater Interfaces. 2020 Mar 04;12(9):11026-11035. doi: 10.1021/acsami.9b23212. Epub 2020 Feb 24.

We report on mechanically strong, water-insoluble hydrogen-bonded nanofiber mats composed of a hydrophilic polymer and a natural polyphenol that exhibit prolonged antioxidant activity. The high performance of fibrous mats resulted from the formation of a network of hydrogen bonds...

Cationic Fluoropolyphosphazenes: Synthesis and Assembly with Heparin as a Pathway to Hemocompatible Nanocoatings.

ACS applied bio materials

Marin A, Brito J, Sukhishvili SA, Andrianov AK.
PMID: 35014813
ACS Appl Bio Mater. 2021 Dec 27; doi: 10.1021/acsabm.1c01099. Epub 2021 Dec 27.

The development of state-of-the-art blood-contacting devices can be advanced through integrating hemocompatibility, durability, and anticoagulant functionalities within engineered nanoscale coatings. To enable all-aqueous assembly of nanocoatings combining omniphobic fluorinated features with the potent anticoagulant activity of hydrophilic heparin, two...

Biocompatible Nanocoatings of Fluorinated Polyphosphazenes through Aqueous Assembly.

ACS applied materials & interfaces

Selin V, Albright V, Ankner JF, Marin A, Andrianov AK, Sukhishvili SA.
PMID: 29505245
ACS Appl Mater Interfaces. 2018 Mar 21;10(11):9756-9764. doi: 10.1021/acsami.8b02072. Epub 2018 Mar 12.

Nonionic fluorinated polyphosphazenes, such as poly[bis(trifluoroethoxy)phosphazene] (PTFEP), display superb biocompatibility, yet their deposition to surfaces has been limited to solution casting from organic solvents or thermal molding. Herein, hydrophobic coatings of fluorinated polyphosphazenes are demonstrated through controlled deposition of...

Endowing surfaces with multiple advanced functionalities, such as temperature-controlled swelling or the triggered release of functional small molecules, is attractive for a large variety of applications ranging from smart textiles to advanced biomedical applications. This Invited Feature Article summarizes...

Hydrogen-bonded polymer complexes and nanocages of weak polyacids templated by a Pluronic® block copolymer.

Wang Y, Sukhishvili SA.
PMID: 27722711
Soft Matter. 2016 Oct 26;12(42):8744-8754. doi: 10.1039/c6sm01869f.

We investigate the phase behavior, morphology, and temperature response of hydrogen-bonded assemblies formed by a triblock copolymer Pluronic® F127 (F127) and polycarboxylic acids of varied hydrophobicity and chain lengths. As confirmed by FTIR, the complexes of poly(acrylic acid) (PAA)...

Determination of film thickness and refractive index in one measurement of phase-modulated ellipsometry.

Journal of the Optical Society of America. A, Optics, image science, and vision

J Opt Soc Am A Opt Image Sci Vis. 2006 Oct;23(10):2639-44. doi: 10.1364/josaa.23.002639.

Ellipsometry is often used to determine the refractive index and/or the thickness of a polymer layer on a substrate. However, simultaneous determination of these parameters from a single-wavelength single-angle measurement is not always possible. The present study determines the...
