“…Eupholus magnificus (23), Sulawesiella rafaelae (24), and Sternotomis pulchra bifasciata (29)), these studies have either mostly focused on their optical properties with structural information being inferred from 2D cross-sections only or were limited in their characterization to structure diagnosis. An in-depth characterization of the network structures is however critical not only to understand the optical properties, but also the underlying cellular processes leading to their formation, which could inform new approaches to the design and manufacture of bio-inspired optical devices (57,58). Although the precise intracellular mechanism of scale formation in beetles is unknown, it is possibly homologous to the growth of butterfly scales that form as a result of the co-assembly of an infolding lipid-bilayer membrane and cuticle in the lumen of the developing scale (10,59).…”

“…Besides the coloration of fabricated products, astonishing examples and a large variety of colors are found in nature. [ 192 ] All living organisms, such as animals and plants, as well as several minerals show coloration effects, often caused by their structure. [ 187,193,194 ] These structurally colored materials, also called photonic pigments or photonic balls in the case of spherically shaped SPs, are of great interest in current research and could potentially replace conventionally used dyes and pigments in many applications.…”

The indispensable transformation to a (more) sustainable human society on this planet heavily relies on innovative technologies and advanced materials. The merits of nanoparticles (NPs) in this context are demonstrated widely during the last decades. Yet, it is believed that the impact of particle‐based nanomaterials to sustainability can be even further enhanced: taking NPs as building blocks enables the creation of more complex entities, so‐called supraparticles (SPs). Due to their evolving phenomena coupling, emergence, and colocalization, SPs enable completely new material functionalities. These new functionalities in SPs can be utilized to render six fields, essential to human life as it is conceived, more sustainable. These fields, selected based on an entropy‐rate‐related definition of sustainability, are as follows: 1) purification technologies and 2) agricultural delivery systems secure humans “fundamental needs.” 3) Energy storage and conversion, as well as 4) catalysis enable the “basic comfort.” 5) Extending materials lifetime and 6) bringing materials back in use ensure sustaining “modern life comfort.” In this review article, a perspective is provided on why and how the properties of SPs, and not simply properties of individual NPs or conventional bulk materials, may grant attractive alternative pathways in these fields.

“…These nanostructures occur in nature (e.g., the bright gold and silver colors of jewel scarabs [ 148 ] and the blue color of the wings of Morpho butterflies) [ 149 ]. Bioinspired nanostructured materials exhibiting photonic properties and structural colors have been fabricated for various purposes by controlling composition, additives, and arrangement, among others [ 150 ]. Proving its usefulness in HTS, the ability of PCs to identify modulators of protein–protein interactions [ 151 ], to discover inhibitors of protein–DNA interactions [ 152 ] ( Figure 6 ), and to measure antibody–antibody binding [ 153 ] has been demonstrated.…”

Optical biosensors are used in numerous applications and analytical fields. Advances in these sensor platforms offer high sensitivity, selectivity, miniaturization, and real-time analysis, among many other advantages. Research into bioactive natural products serves both to protect against potentially dangerous toxic compounds and to promote pharmacological innovation in drug discovery, as these compounds have unique chemical compositions that may be characterized by greater safety and efficacy. However, conventional methods for detecting these biomolecules have drawbacks, as they are time-consuming and expensive. As an alternative, optical biosensors offer a faster, simpler, and less expensive means of detecting various biomolecules of clinical interest. In this review, an overview of recent developments in optical biosensors for the detection and monitoring of aquatic biotoxins to prevent public health risks is first provided. In addition, the advantages and applicability of these biosensors in the field of drug discovery, including high-throughput screening, are discussed. The contribution of the investigated technological advances in the timely and sensitive detection of biotoxins while deciphering the pathways to discover bioactive compounds with great health-promoting prospects is envisaged to meet the increasing demands of healthcare systems.
