In living systems, there is emerging evidence that nature uses liquid-liquid phase separation (LLPS) to organize diverse cellular processes such as signal transduction, translation regulation, and gene expression among chemical chaos. Inspired by the naturally occurring LLPS, there is increasing interest in the deployment of LLPS in synthetic biosystems towards a wide range of applications. Although much progress has been made, there is still a limited understanding of LLPS in synthetic biosystems. Importantly, studies in LLPS in non-living systems (i.e., polymer systems) and in living systems have been progressed separately. There is an urgent need to summarize and integrate our current understanding of LLPS in different systems to inform the design of artificial LLPS in synthetic biosystems. In this review, we first summarize the development of theoretical modeling of LLPS in non-living systems and living systems. We then explore current approaches for the construction and functionalization of LLPS in synthetic biosystems. We finally review the state of the art of LLPS in synthetic biosystems towards applications in synthetic biology, cellular engineering and biotechnology.

The exploration and development of natural biopolymer-based hydrogels can be traced back to the 18th century. The rising interest in these hydrogels is largely due to their soaring demand in diverse applications such as tissue engineering, bio-separation, drug delivery, smart bioelectronics, and eco-friendly agriculture. However, one major drawback of these naturally derived biopolymer-based hydrogels is their subpar mechanical properties characterized by limited stretchability, modulus, and resilience, along with inadequate water adsorption capability. This restricts their broad-spectrum applicability. These biopolymers are typically crosslinked through different strategies to rectify these issues and functional groups present in polymer chains play crucial roles in crosslinking strategies. Consequently, the understanding of the chemical structure-function relationship in the crosslinked polymeric network is paramount for the design of an effective natural biopolymer-based hydrogel. A profound comprehension of the behavior of functional groups during crosslinking is therefore essential. This review provides a comprehensive overview of the chemistries of functional group interactions in natural biopolymers that are utilized in the development of functional hydrogels. Various categories of functional group interaction chemistries are examined and discussed in terms of crosslinking strategies (e.g., hydrogen bonding, ionic interaction, hydrophobic interaction) for hydrogel formation. Furthermore, the types, properties, and cutting-edge applications of resultant natural biopolymer-based hydrogels are outlined along with a discussion of the future prospects in this field of research.

In the current era of globalization, the exponential surge in the production, consumption, and disposal of agricultural and post-consumer polymeric waste material has emerged as a pressing environmental concern of paramount importance. The current situation, wherein the presence of plastic particles and other plastic-based contaminants in the food supply chain is increasingly evident, poses a profound health risk to mankind. In this regard, the utilization of conventional waste management practices, such as, open burning, landfilling, and incineration, leads to adverse consequences, like, the emission of greenhouse gases and substantial economic losses. To encounter such problems, researchers are actively engaged in the development of innovative recycling processes aimed at closed-loop circular economy by transforming these wastes into sustainable value added products. This comprehensive review emphasizes the necessity of sustainable recycling of lignocellulosic biomass and synthetic plastic wastes, with a specific focus on their transformation into biodegradable polymers and their potential biomedical applications. Moreover, we have critically discussed the recent trends and drivers in this field, global environment threat, different recycling route of lignocellulosic biomass and synthetic polymer wastes. Furthermore, this review provides a detailed discussion on the applications of these biodegradable polymers in the field of tissue engineering, drug delivery, and antimicrobial applications. Additionally, we have also addressed the critical challenges involved in this field and possible solutions to overcome them.

As an important component of future electronic devices, photodetectors require mechanical flexibility, and stretchability to meet the demands of conformal, portable, and lightweight applications. As expected, flexible photodetectors (FPDs) were born timely and have obtained rapid development driven by the considerable progress of the optoelectronic industry. Especially, FPDs appear to serve as a bridge between electronic information systems and biological systems due to their potential functional applications including wearable devices, artificial intelligence, bionics devices, etc. However, the poor mechanical stability, narrow spectral response range, low responsivities and difficulty in miniaturization of traditional FPDs have greatly limited their commercial and industrial applications. One of the most promising routes toward addressing the inherent shortcomings of FPDs is through constructing novel micro/nano-structured integrated flexible detection systems to achieve diverse functions and enhance performance, hence facilitating flexible integration. In this review, the recent advances in performance-enhancing strategies for FPDs are outlined and discussed. First, the detection mechanism, performance enhancement mode, and key figures-of-merit of FPDs are summarized and basic design principles of the FPDs are discussed emphatically. Then, recent progress in structural engineering-based performance enhancement of FPDs is reviewed, categorized by the types of enhancement, electric field manipulation engineering, strain engineering, and optical field manipulation engineering. Moreover, this review also summarizes the integration strategies for the application of FPDs and finally puts forward the challenges and future research directions in these fields.

Mechanical Metamaterials (MMs) are artificially designed structures with extraordinary properties that are dependent on micro architectures and spatial tessellations of unit cells, rather than constitutive compositions. They have demonstrated promising and attractive application potentials in practical engineering. Recently, how to rationally design novel MMs and discover their multifunctional behaviors has received tremendous discussions with rapid progress, particularly in the last ten years with an enormous increase of publications and citations. Herein, we present a comprehensive overview of considerable advances of MMs, including critical focuses at different scales, forward and inverse design mechanisms with optimization formulations, micro architectures of unit cells, and their spatial tessellations in discovering novel MMs and future prospects. The implications in clarifying the four focuses at levels from the global to the physical in MMs are highlighted, that is, unique structures designed for unique functions, unique micro unit cells placed in unique locations, unique micro unit cells designed for unique properties and unique micro unit cells evaluated by unique mechanisms. We examine the inverse designs of MMs with intrinsic mechanisms of structure-property driven characteristics to achieve unprecedented behaviors, which are involved into material designs and multiscale designs. The former primarily optimizes micro architectures to explore novel MMs, and the latter focuses on micro architectures and spatial tessellations to promote multifunctional applications of MMs in engineering. Finally, we propose several promising research topics with serious challenges in design formulations, micro architectures, spatial tessellations and industrial applications.

Lead halide perovskites with excellent optoelectronic properties have attracted extensive attention and made amazing progress for X-ray detectors and imaging. However, lead is highly toxic to humans, animals and ecosystems, posing a great safety concern to its commercial application. It has become an urgent need to develop stable and environment-friendly lead-free alternatives. In this review, we summarize recent progress in lead-free halide perovskites (LFHPs) and derivatives toward X-ray detectors and imaging. First, we introduce the working principle of X-ray detectors and the key figure of merit in direct and indirect detection processes. In addition, we summarize state-of-the-art lead-free halide perovskites preparation methods. Furthermore, we comprehensively discuss the structural dimensions, optoelectronic properties of lead-free halide perovskites and their recent advances in X-ray detection and imaging. Meanwhile, the stabilities of LFHPs-based X-ray detectors are discussed.

Portable, affordable, and miniaturized electrochemical sensors for point-of-care diagnostic devices represent a step towards achieving the United Nations’ Sustainable Development Goal 3: Good Health and Well-Being. Over the last 10 years, rapid advancements in three-dimensional (3D) printing technology (additive manufacturing) have enabled the production of low-cost, miniature 3D printed (3DP) devices for bio-chemical sensing, enabling innovation in healthcare diagnostics for everyone regardless of their economic background or geographical location. Compared to traditional manufacturing processes, 3D printing offers numerous advantages for miniaturized electrochemical point-of-care diagnostic devices, such as rapid prototyping, custom-shaped devices, flexible fabrication designs, low energy consumption, reduced time to market, and reduced waste generation. This article reviews recent developments in 3DP electrochemical sensors, including the printing of composite materials, advanced electrode architectures, activation and functionalization methods, and electrochemical sensing performance (i.e. sensitivity, linear range, limits of detection) towards various analytes, including heavy metals/water pollutants, toxic/explosive substances, neurotransmitters/stimulants, metabolites, DNA, amino acids, proteins, viruses, and food pathogens. Moreover, we discuss the remaining challenges and gaps in current knowledge and solutions to improve the electroanalytic performance of 3DP electrodes for future biomedical applications in wearable and smart-implantable sensor systems of the future.
