“…An addition of Rhodamine B resulted in a small change in the contact angle, to 90.7 • (Figure 4c), whereas the surface of the hydrogel with addition of nanoparticles proved the most hydrophilic of all samples obtained and its contact angle was 71.8 • , 12 degrees greater than the contact angle of glycol-modified chitosan membrane, i.e., 59.4 • . The CA analysis carried out on the layers is suitable to observe changes in the wetting properties of the surface after the functionalisation process with different atoms [33] or after the addition of compounds with other groups (-OH of glycerol). The time changes in the measured contact angles for all chitosan membranes studied are presented in Figure 5.…”

Fluorescent particles are of particular interest as probes and active agents for biomedical, pharmaceutical, and food applications. Here, we present two strategies for incorporation of core-shell acrylic fluorescent nanoparticles (NPs) with Rhodamine B (RhB) as a dye into a chitosan (CS) matrix. We selected two variants of NPsRhB immobilisation in a CS membrane and biopolymeric CS beads. Modification of the method for production of the biopolymer cover/transporter of nanoparticles allowed two series of hydrogels loaded with nanoparticles to be obtained with a similar concentration of the aqueous solution of the nanoparticles. Microscopic analysis showed that the NPs were nonuniformly distributed in millimetre-sized CS beads, as well as membranes, but the fluorescence signal was strong. The composition of CS layers loaded with nanoparticles (CS/NPsRhB) showed water vapour barrier properties, characterised by the contact angle of 71.8°. Finally, we incorporated NPsRhBCS beads into a gelatine matrix to check their stability. The results confirmed good stability of the NPsRhBCS complex system, and no dye leakage was observed from the beads and the membranes. The proposed complex system demonstrated promising potential for further use in bioimaging and, thus, for the development of advanced diagnostic tools.

“…As the Cr content increased, the size of grains was reduced (Scheme ). Furthermore, the surface porosity percent, the mean value roughness and the grain size decreased; So, the hydrophilic properties were increased, and the contact angle was reduced . The decline of the hydrophobic property of Cr@mesoporous titania thin films were synthesized by sol‐gel calcined at 400 °C was established herein.…”

Attention to the mesoporous metal doped titania thin films has been increased significantly due to its wide potential applications, especially in photocatalytic activities. Determining the effect of surface property, mesoporous symmetry and metal dopant in mesoporous thin films materials have rarely reported, in particular, there are essential factors determining the performance of these materials. Herein, Cr@mesoporous titania thin films prepared by the sol‐gel approach. The surface properties of the thin films, as well as crystal structure, mesoporous symmetry, hydrophobicity, and surface morphology, were deeply discussed. Power spectral density and bearing analysis were calculated using atomic force microscopy. The results confirm that the thickness of all films was completely uniform without flooding, made by randomly oriented fine grains, and mesoporous structure. The Cr particles act as a porous site eliminator and increased the lattice mismatch in mesoporous titania thin films. The surface roughness, power spectral density, bearing area, and water contact angle of the films were significantly affected by Cr content. As the Cr content is increased, the porosities shrunk together and denser films were obtained. The roughness values display that the presence of Cr increases the homogeneity and the smoothness of the thin film surface with small grain size.
