Gold nanoparticles represent nanosized colloidal entities with high relevance for both basic and applied research. When gold nanoparticles are functionalized with polymer-molecule ligands, hybrid nanoparticles emerge whose interactions with the environment are controlled by the polymer coating layer: Colloidal stability and structure formation on the single particle level as well as at the supracolloidal scale can be enabled and engineered by tailoring the composition and architecture of this polymer coating. These possibilities in controlling structure formation may lead to synergistic and/or emergent functional properties of such hybrid colloidal systems. Eventually, the responsivity of the polymer coating to external triggers also enables the formation of hybrid supracolloidal systems with specific dynamic properties. This review provides an overview of fundamentals and recent developments in this vibrant domain of materials science.

Detection of viruses, including coronavirus (SARS-CoV-2), via facile, fast, and optical methods is highly important to control pandemics. In this regard, optically-active nanomaterials and nanoparticles (NPs) are a wise choice due to their long-term stability, ease of functionalization, and modifications. In this work, a nanocomposite based on NiFe layered double hydroxide (LDH) and ZIF-67 metal-organic framework (MOF) was designed and synthesized, and decorated on the surface of the melt-blown mask.

Background: Viral epidemics have long endangered human health and had dramatic impacts on environment and society. The currently known viruses and the rapid emergence of previously unknown viruses lead to an urgent need for effective virus detection strategies. It is important to develop methods that can detect multiple related viruses simultaneously in order to improve detection efficiency and to avoid treatment delays due to misdiagnoses.

Objective: Currently, nasolabial folds are mainly removed by invasive procedures, resulting in long-lasting changes, as non-surgical user-implementable alternatives are scarce and inefficient. For example, the use of coating films for this purpose has thus far faced substantial difficulties because such films should combine the antithetical properties of shrinkability and flexibility. Herein, we challenge this status quo by identifying a polymer that simultaneously exhibits shrinkability and flexibility and using this polymer to develop a cosmetic formulation for immediate and non-invasive nasolabial fold removal.

Cancer photoimmunotherapy represents an intelligent and highly efficient therapeutic approach that harnesses the photothermal effect to precisely target and ablate tumor tissues, while simultaneously modulating the immune system to achieve tumor elimination. The integration of multifunctional therapeutic modalities for combined photoimmunotherapy requires advanced drug delivery systems. However, the design of a single nanoagent capable of serving as a multifunctional nanophotosensitizer remains a significant challenge.

Extracellular Polymeric Substances (EPS) are ubiquitous in biological wastewater treatment (WWT) technologies like activated sludge systems, biofilm reactors, and granular sludge systems. EPS recovery from sludge potentially offers a high-value material for the industry. It can be utilized as a coating in slow-release fertilizers, as a bio-stimulant, as a binding agent in building materials, for the production of flame retarding materials, and more.
