Hydrogen-bonded polymer multilayers probed by neutron reflectivity.

Langmuir : the ACS journal of surfaces and colloids

Kharlampieva E, Kozlovskaya V, Ankner JF, Sukhishvili SA.
PMID: 18816021
Langmuir. 2008 Oct 21;24(20):11346-9. doi: 10.1021/la802502c. Epub 2008 Sep 24.

We present a neutron reflectivity study of the internal structure of multilayers made of a weak polyelectrolyte and a neutral component where interactions between adjacent layers are controlled by hydrogen-bonding. We found the degree of interpenetration of polymer layers...

Noble metal nanostructure both as a SERS nanotag and an analyte probe.

Chemical communications (Cambridge, England)

Pinkhasova P, Puccio B, Chou T, Sukhishvili S, Du H.
PMID: 22918437
Chem Commun (Camb). 2012 Oct 09;48(78):9750-2. doi: 10.1039/c2cc35173k.

We report nanotags encapsulated in Au-Ag nanostructure that are active in surface-enhanced Raman scattering. The Au-Ag nanoshells are filled with Ag via citrate reduction, entrapping label molecules in the process. The nanotags can be used for quantitative SERS measurements...

Ocean Salinity Sensing Using Long-Period Fiber Gratings Functionalized with Layer-by-Layer Hydrogels.

ACS omega

Yang F, Hlushko R, Wu D, Sukhishvili SA, Du H, Tian F.
PMID: 31459461
ACS Omega. 2019 Jan 28;4(1):2134-2141. doi: 10.1021/acsomega.8b02823. eCollection 2019 Jan 31.

Rapid, accurate, and real-time measurements of ocean salinity are of great importance for a host of scientific, commercial, and defense applications. We demonstrate a highly sensitive, fast-responding fiber-optic salinity sensor that integrates long-period fiber gratings (LPFGs) with ionic strength-responsive...

Self-Healing Phase Change Salogels with Tunable Gelation Temperature.

ACS applied materials & interfaces

Karimineghlani P, Palanisamy A, Sukhishvili SA.
PMID: 29633618
ACS Appl Mater Interfaces. 2018 May 02;10(17):14786-14795. doi: 10.1021/acsami.8b03080. Epub 2018 Apr 19.

Chemically cross-linked polymer matrices have demonstrated strong potential for shape stabilization of molten phase change materials (PCM). However, they are not designed to be fillable and removable from a heat exchange module for an easy replacement with new PCM...

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. 2022 Jan 17;5(1):313-321. 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...

Integrating Antioxidant Functionality into Polymer Materials: Fundamentals, Strategies, and Applications.

ACS applied materials & interfaces

Brito J, Hlushko H, Abbott A, Aliakseyeu A, Hlushko R, Sukhishvili SA.
PMID: 34448558
ACS Appl Mater Interfaces. 2021 Sep 08;13(35):41372-41395. doi: 10.1021/acsami.1c08061. Epub 2021 Aug 27.

While antioxidants are widely known as natural components of healthy food and drinks or as additives to commercial polymer materials to prevent their degradation, recent years have seen increasing interest in enhancing the antioxidant functionality of newly developed polymer...
