Smart nanocarriers for drug delivery: controllable LSPR tuning

Autor: Lopatynskyi, A.M., Lytvyn, V.K., Mogylnyi, I.V., Rachkov, O.E., Soldatkin, O.P., Chegel, V.I.

Gold nanostructures are considered as a potential platform for building smart nanocarriers that will form the basis of novel methods of targeted delivery and controlled release of drugs. However, to ensure maximum efficiency of gold nanoparticles upo

Plasmon-enhanced fluorometry based on gold nanostructure arrays. Method and device

Autor: Chegel, V.I., Lytvyn, V.K., Lopatynskyi, A.M., Shepeliavyi, P.E., Lytvyn, O.S., Goltvyanskyi, Yu.V.

In this work, we describe a method of surface-enhanced fluorometry, based on the phenomenon of localized surface plasmon resonance in unordered gold nanostructure arrays. The theoretical approach for the model system "gold nanoparticle-dielectric spa

Localized surface plasmon resonance in Au nanoprisms on glass substrates

Autor: Lopatynska, O.G., Lopatynskyi, A.M., Borodinova, T.I., Chegel, V.I., Poperenko, L.V.

Metal nanocrystals are actual objects for the modern biophysics mainly because of their usage in sensors based on localized surface plasmon resonance (LSPR) and as active substrates for surface-enhanced spectroscopies. This work deals with the experi

Preparation of Au Nanostructure Arrays for Fluorometry and Biosensors Applications

Autor: Chegel, V.I., Lopatynskyi, A.M., Lytvyn, V.K., Nazarenko, V.I., Guo, J.L., Lucas, B.D.

The paper describes the fabrication of random and ordered gold nanostructure arrays (NSA) of different morphology using island film thermal annealing and nanoimprint lithography techniques. Structural parameters of obtained NSA were investigated usin

Factor of interfacial potential for the surface plasmon-polariton resonance sensor response

Autor: Lopatynskyi, A.M., Lopatynska, O.G., Poperenko, L.V., Chegel, V.I., Guiver, M.D.

In this work, we investigate how the application of an external potential difference to the sensitive gold-electrolyte interface influences the optical response of a sensor based on the surface plasmon-polariton resonance (SPPR). The SPPR resonant an
