Optical properties of hydrogels filled with dispersed nanoparticles

Abstract

Abstract.1 This paper reports on a study of novel heterohydrogel materials with regular inclusions of the dispersed phase such as polystyrene latex nanoparticles. Synthesized 3D hydrogel matrices contain a balanced number of cross-links and a defined amount of polystyrene nanoparticles with 50 or 85 nm in radius. This study has shown that the obtained hydrogel matrices are capable of changing the swelling degree and their optical properties depending on the size and concentration of the dispersed nanoparticles. The results of the performed studies revealed that the synthesized 3D hydrogels are sensitive for even small changes of glucose concentration and therefore are very promising materials for biosensors.

Improving the Long-Term Performance of Poly(Vinyl Chloride)

“…[2][3][4] Hydrogels are currently used to make various implants, contact lens materials, bandages for the treatment of wounds and burns, controlled release of drugs, etc. [5][6][7][8][9][10] The use of polymeric hydrogel materials (mainly in film form) as transdermal long-acting therapeutics is widespread. [11][12][13] The use of film hydrogel therapies is applied due to the prolonged active action because of the controlled diffusion of drugs from the film volume.…”

Novel Ni/pHEMA-gr-PVP Composites Obtained by Polymerization with Simultaneous Metal Deposition: Structure and Properties

“…To date, there has been widespread interest, both in science and practice, among the metal-polymeric composites in new materials with specific characteristics, known as metal-containing polymeric hydrogels [7]. Polymeric hydrogels are materials with a porous structure [8,9], which, in combination with the presence of hydrophilic functional groups, provides swelling of the polymer matrix in water and other polar solvents [10] that results in their high permeability for dissolved low-molecular substances [11,12]. The uniqueness of the metal-containing hydrogels is that they combine the properties of the hydrogel matrix and the metal filler [13].…”

“…The introduction of metal particles into the structure of hydrogels opens additional possibilities for providing them with new properties, for example, bactericidal, antifungal, fluorescent, optical, catalytic, electrical, and magnetic properties, as well as their changes in the desired direction. Such materials are already used in biotechnology and medicine [14]; in the production of packaging materials [15], microelectronics [7], optics and optoelectronics [9], chemical catalysis [16,17], and sensory devices [18]; and in other industries.…”

Switching it Up: The Promise of Stimuli‐Responsive Polymer Systems in Biomedical Science

“…GOx-modified polymers can detect glucose levels by producing measurable changes in pH, oxygen consumption, or hydrogen peroxide concentration. [148] In the paper [149] 3D hydrogels filled with polystyrene nanoparticles were synthesized and were shown to be sensitive even to small changes in glucose concentration and, therefore, to be very promising materials for the fabrication of biosensors.…”
