Unlike conventional inorganic materials, biological systems are exquisitely adapted to respond to their surroundings. Proteins and other biological molecules can process a complex set of chemical binding events as informational inputs and respond accordingly via a change in structure and function. We applied this principle to the design and synthesis of inorganic materials by preparing nanoparticles with reconfigurable surface ligands, where interparticle bonding can be programmed in response to specific chemical cues in a dynamic manner. As a result, a nascent set of "transmutable nanoparticles" can be driven to crystallize along multiple thermodynamic trajectories, resulting in rational control over the phase and time evolution of nanoparticle-based matter.

P-doped strategy exhibits remarkable advantages in the field of environmental catalytic materials due to its excellent charge modulation ability and enhanced chemical stability. Although the current SiO-based aerogel materials have outstanding high specific surface area properties, their lack of stability and poor electrical conductivity limit their application potential. Herein, the SiO aerogel confined material with P-doped CoO nanoparticles (P-Co@SiO2 aerogel) was constructed for the removal of tetracycline (TC) from water by the activation of peroxymonosulfate (PMS).

The therapeutic potential of RNA and DNA is evident from numerous formulations approved by the FDA in recent years, with formulations based on RNAi standing out as a successful example. The new class of medicines based on RNAi combines the process of diagnosis and treatment via sequence-specific recognition of biomarker mRNAs and downregulation of their translation. While this approach proved clinically successful, safer, and more personalized options that mitigate adverse effects can be revealed by separating diagnostic and treatment steps.

Gene therapy holds immense potential for treating genetic disorders, malignancies, and infectious diseases through the targeted introduction, silencing, or precise editing of therapeutic genes. Although viral vectors exhibit exceptionally high gene transfection efficiency, their clinical application faces significant challenges, including robust immunogenicity, the insertional mutagenesis risks, complex and costly manufacturing processes hindering large-scale manufacturing, limited gene cargo capacity, and poor packaging efficiency for large genes. In contrast, nonviral vectors-such as lipid nanoparticles (LNPs), cationic polymers, and inorganic nanoparticles, offer numerous advantages, including superior safety profiles, the scalability for manufacturing, structural and functional reconfigurability in accommodating various sizes cargo.

Hydrogen, a clean and renewable energy carrier, necessitates advanced sensing technologies for safe and efficient utilization. Here, we present a tunable flexible plasmonic sensor based on a disordered system composed of upper palladium (Pd) nanoparticles (NPs), a poly(methyl methacrylate) (PMMA) spacer, a lower Pd film, and a soft substrate. The contributions of Pd NPs and Pd films to the optical response at various hydrogen concentrations are different.

The fabrication of assembled structures of topological defects in liquid crystals (LCs) has attracted much attention during the last decade, stemming from their potential applications in modern technologies, including photonic devices, tunable optical elements, and soft actuators. A range of techniques can be employed to create large areas of engineered defects in LCs, including mechanical shearing, chemical surface treatment, external fields, or geometric confinement. 3D printing has recently emerged as a powerful technique for fabricating novel patterning topographies, particularly enabling the confinement of LCs in geometries with curved surfaces that are challenging to achieve with conventional microfabrication methods.
