“…In addition, composite materials have gained interest as light-responsive components because they combine the merits of organic and inorganic components. As an example, micelle-, liposome-, and polymer-based materials modified with light-responsive parts can be fabricated [21][22][23]. Moreover, the inspiration from the biological side leads to the development of the cell-based delivery systems possessing light-addressable properties.…”

Drug carriers with intelligent functions are powerful therapeutic and diagnostic platforms in curing various diseases such as malignant neoplasms. These functions include the remote noninvasive activation of drug using physical impacts, e.g. light exposure. Combination of different therapeutic modalities (chemotherapy, photodynamic therapy, and so forth) with light-responsive carriers enables promising synergetic effect in tumour treatment. The main goal of this review article is to provide the state of the art on light-sensitive delivery systems with the identification of future directions and their implementation in tumour treatment. In particular, this article reviews the general information on the physical and chemical fundamental mechanisms of interaction between light and carrier systems (e.g. plasmonic and dielectric nanoparticles), the design of optically responsive drug carriers (plain and composite), and the mechanisms of light-driven controlled release of bioactive compounds in biological environment. The special focus is dedicated to the most recent advances in optically responsive bioinspired drug vehicles.

“…Furthermore, coatings can be obtained on surfaces with complex shapes to provide additional functionality, for example, coatings containing arrays of closed cavities can be obtained (so-called microchambers) to store and release functional cargo in a controlled manner. Functionalisation of microchambers by graphene oxide enabled release on demand by near-infrared (NIR) laser in the "therapeutic window" [153], Figure 6. An unusual application of graphene oxide was shown by the binary hybrid-filled LbL coatings, composed of graphene oxide and β-FeOOH nanorods, which enabled the reduction of flammability of polyurethane foams [154].…”

Originally regarded as auxiliary additives, nanoparticles have become important constituents of polyelectrolyte multilayers. They represent the key components to enhance mechanical properties, enable activation by laser light or ultrasound, construct anisotropic and multicompartment structures, and facilitate the development of novel sensors and movable particles. Here, we discuss an increasingly important role of inorganic nanoparticles in the layer-by-layer assembly—effectively leading to the construction of the so-called hybrid coatings. The principles of assembly are discussed together with the properties of nanoparticles and layer-by-layer polymeric assembly essential in building hybrid coatings. Applications and emerging trends in development of such novel materials are also identified.

“…Moreover, the LbL technique can be combined with 3d pattering approach resulting in hollow architecture desired in many applications . Recently, this approach was applied in order to produce hollow microchambers based on polymers and graphene oxide or carbon dots with improved mechanical properties and high light responsiveness . Besides, thermal treatment was reported to improve barrier properties of LbL‐assembled microstructures that makes it prospective to investigate thermal carbonization processes in these polyelectrolyte‐based materials .…”

We report a facile route for the fabrication of thin composite films based on polyelectrolytes and carbon nanostructures. Composite films were made by layer‐by‐layer assembly of polyelectrolyte multilayers utilizing embedded dextran sulfate (Dex) solution as a carbon source. Raman measurements indicate the formation of carbon nanostructures from the Dex precursor over the whole film. Formation of these nanostructures results in enhanced photoluminescence and an increase in conductivity by two orders of magnitude to about 0.055 S cm−1. The latter corresponds to the level of wide‐gap semiconductors, in contrast to the initial insulating polyelectrolyte film. A distinct peak of photoluminescence of the films is found in the blue region at the wavelength of 450 nm. © 2019 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2019, 136, 47718.
