Among these, simplification, automation, and miniaturization of (bio)analytical/diagnostic devices and methods, and more recently, their coupling with new emerging and ubiquitous technologies such as smartphones have witnessed significant growth. [1c,d,2] The universal availability (with an estimate of ≈5 billion smartphone users by 2019), affordability, ease-of-use, portability, and other useful and fascinating features of smartphones as miniature computers with fast operating systems, high-quality cameras, large memories, powerful and rechargeable batteries, several wireless connectivity and data transferring modes, touch screen, USB and audio ports, and so on make them as promising and appealing platforms/tools in analytical chemistry and particularly in (bio)sensing/diagnostics technology. [1c,2b-d,3] Although significant developments have already been reached in terms of smartphone applications in (bio)analytical systems, a substantial gap still remains in moving smartphone-based analytical/diagnostic devices (SADs) from purely sensing and data analyzing platforms toward more functional and integrated analytical devices that can fulfill most of the (bio)analytical/diagnostic procedures, which often require multiple steps of mixing, separating/centrifuging, analyzing, and microscopy. Because of this obstacle, the applications of SADs are greatly limited, especially in resource-limited settings and at the POC and POU, where access to routine laboratory equipment is usually either lacking or very limited. [3b,4] In the present study, for the first time, to the best of our knowledge, we have fabricated a fully integrated smartphonebased compact miniaturized analytical/diagnostic device that can perform most of the main steps of (bio)analytical/diagnostic procedures including separating/centrifuging, mixing, analyzing, and microscopy steps, and also able to meet the prerequisites of Analytics and Healthcare 4.0 through Internet of Things (IoT) concept, which nowadays owing to linking the machines, devices, and sensors to the Internet and its promising features is known as a "megatrend" in analytical chemistry. [5] Analytics 4.0 includes technologies that are prepared for automation, connection, and processing to comprehend and analyze data. It is related to the decentralization of data that are Despite the significant advancements in smartphone technology in Healthcare/Analytics 4.0 era, a substantial gap has still remained in moving smartphone-based analytical/diagnostic devices (SADs) from purely analyzing systems toward smart fully integrated systems/devices that can perform all the different steps of (bio)analytical/diagnostic procedures thoroughly and with high efficiency. Here, the first smart, portable, and compact miniaturized analytical/diagnostic device is presented that integrates the main steps of (bio)analytical/diagnostic procedures, including mixing, separating/ centrifuging, analyzing, and microscopy, also the Internet of Things concept onto a platform that entirely operates using smartphone.

“…Natural product-derived compounds are one of the most significant bioactive nature-based compounds due to their natural availability, renewability, sustainability, biodegradability, and biocompatibility compared to the pure artificial chemicals. 22 Among them, rosin is a renewable and sustainable natural resource, which is nevertheless limited to low value-added applications in current industry. In order to add high values of the rosin-derived biomaterials, we have herein succeeded a new class of BioAIEgens from the abundant and low-cost natural rosin via facile Schiff base reactions.…”

“…Alternatively, plantoriginated chemicals are green and bioactive compounds that have been widely studied as one of the most interesting naturebased compounds in the advanced (bio)sensing fields because of their numerous inherent and unique characteristics, such as natural availability, renewability, sustainability, biodegradability, and biocompatibility. 22 Hence, AIEgens from natural resources have recently gained researchers' intense attention ( Figure S1). [23][24][25][26][27][28][29][30][31][32] To date, some natural product-based AIEgens including natural polymers (sodium alginate and bovine serum albumin) and small molecules (quercetin, myricetin, and berberine chloride) have been investigated with unique advantages in bioapplications.…”

<p>The exploration of artificial luminogens with bright emission has been fully developed with the advancement of synthetic chemistry. However, many of them face problems like weakened emission in the aggregated state as well as poor renewability and sustainability. Therefore, the development of renewable and sustainable luminogens with anti-quenching function in the solid state, as well as to unveil the key factors that influence their luminescence behavior become highly significant. Herein, a new class of natural rosin-derived luminogens with aggregation-induced emission property (AIEgens) have been facilely obtained with good biocompatibility and targeted organelle imaging capability as well as photochromic behavior in the solid state. Mechanistic study indicates that the introduction of the alicyclic moiety helps suppress the excited-state molecular motion to enhance the solid-state emission. The current work fundamentally elucidates the role of alicyclic moiety in luminogen design and practically demonstrates a new source to large-scalely obtain biocompatible AIEgens.</p>

Recent advances in novel aerogels through the hybrid aggregation of inorganic nanomaterials and polymeric fibers for thermal insulation

Aerogel is a nanoporous solid material with ultrahigh porosity, ultralow density, and thermal conductivity, which is considered to be one of the most promising high‐performance insulation materials today. However, traditional pure inorganic aerogels (i.e., silica aerogel) exhibit inherent structural brittleness, making their processing and handling difficult, and their manufacturing costs are relatively high, which limits their large‐scale practical use. The recently developed aerogel based on polymer nanofibers has ultralow thermal conductivity and density, excellent elasticity, and designable multifunction. More importantly, one‐dimensional polymer nanofibers are directly used as building blocks to construct the network of aerogels via a gelation‐free process. This greatly simplifies the aerogel preparation process, thereby bringing opportunities for large‐scale aerogel applications. The aggregation of inorganic nanomaterials and polymer nanofibers is considered to be a very attractive strategy for obtaining highly flexible, easily available, and multifunctional composite aerogels. Therefore, this review summarizes the recent advances in novel aerogels through the hybrid aggregation of inorganic nanomaterials and polymeric fibers for thermal insulation. The main processing routes, porous microstructure, mechanical properties, and thermal properties and applications of these aerogels are highlighted. In addition, various future challenges faced by these aerogels in thermal insulation applications are discussed in this review.
