Article Abstract
Butterfly-shaped tetrabenzo[a,c,g,i]fluorene (TBF)-based molecules (1 and 2) were designed, synthesized and well characterized using various spectroscopic techniques. The single crystal X-ray structure of 1 shows the presence of intermolecular 3-D π-π stacking interaction and unprecedented "cold crystallization" in polycyclic aromatic molecules. We report for the first time, the "bottom-up" self-assembly of TBF based organic molecules. The supramolecular studies reveal the formation of vesicles and cuboid-shaped nanocrystals in THF-water and toluene solution, respectively.

Distinctive polymer brushes (PBs) play a crucial role in providing a nonpreferential (neutral) surface for vertical orientation of block copolymers (BCPs). This bottom-up approach effectively aligns the formation of vertical lamellar and cylinder lattice structures from the BCP, which is crucial for nanopatterning and other applications. In conventional BCP self-assembly techniques, random copolymer brushes are commonly employed to achieve substrate neutrality.

Exosomes are nanoscale lipid-bilayer vesicles that mediate intercellular communication by delivering bioactive molecules such as nucleic acids and proteins. Among them, exosomes derived from salivary gland epithelial stem cells (sgESC-Exos) exhibit antifibrotic effects in salivary gland models through the delivery of antifibrotic microRNAs, such as miR-1290 and miR-3162. However, their clinical translation is hindered by low production yield and particle heterogeneity.

Hierarchical assembly of nanosized building blocks has emerged as an effective strategy for the bottom-up fabrication of functional materials with a wide range of potential applications, but large-scale production of well-defined hierarchical colloidal materials still remains challenging. In this study, cross-linked block copolymer micelles with reversible addition-fragmentation chain transfer (RAFT) groups at the interface were prepared by orthogonal RAFT-mediated polymerization-induced self-assembly (PISA) of hydroxypropyl methacrylate (HPMA) in water. These micelles were then used as building blocks for the polymerization-induced hierarchical self-assembly (PIHSA) of -isopropylacrylamide (NIPAM) in water.

Aramid nanofibers (ANFs) have emerged as promising building blocks for bioinspired materials due to their exceptional mechanical strength and chemical stability. However, their widespread application has been hindered by the limitations of conventional top-down synthesis from Kevlar, which is costly, inefficient, and offers limited control over molecular structure. Addressing this challenge, a cost-effective, bottom-up strategy is reported to fabricate limpet-inspired composite fibers by combining the self-assembly of ANFs from poly(paraphenylene terephthalamide) polyanions with in situ iron oxide mineralization.

Metasurfaces, a class of two-dimensional metamaterials, exhibit notable optical properties, making them attractive candidates for applications in fields such as the cloaking, biophotonics, and imaging. The realization of these applications is dependent on advancements in fabrication techniques. Conventional "top-down" lithography often faces limitations, such as polycrystallinity and surface roughness.
