Summary: The interplay of crystal symmetry, strong spin-orbit coupling, and many-body interactions in low-dimensional materials provides a fertile ground for discovering unconventional electronic and magnetic properties and versatile functionalities. In this study, we report the heteroepitaxial growth of a superconducting 2D square-lattice bismuth monolayer on superconducting Pb films. The atomic structure and the presence of a Rashba-type spin-split Dirac band at the Fermi level in the monolayer bismuth films are revealed by density functional theory calculations, and it becomes superconducting through the proximity effect from the Pb substrate. The possibility of a topological superconducting state in this system with magnetic dopants/field is suggested.

Summary: In this paper, collective excitations in an M-BLG heterostructure were studied. The results showed that the heterostructure had two solutions corresponding to optical and acoustical modes, with significantly higher energy compared to DBLG and DLG systems with similar parameters. As temperature increased, the frequency of the acoustical mode steadily increased, while the frequency of the optical mode only increased in large wave vector regions, with different results for different interlayer separations. Interestingly, the effects of carrier density in graphene on plasmon properties of M-BLG heterostructures sharply differed from those in both BLG and DLG systems.

Summary: The study demonstrates a route to realizing fragile 2D quantum states through endotaxial polytype engineering of van der Waals materials, isolating 2D charge density waves and restoring mirror symmetries via interlayer CDW twinning. The newly reported twinned-commensurate charge density wave (tC-CDW) shows a single metal-insulator phase transition at around 350 K and can be mapped using in-situ transmission electron microscopy and nanobeam diffraction. This work introduces a novel approach to access latent 2D ground states distinct from conventional methods.

Summary: Coiled-coil peptides are attractive for biomaterial preparation due to their high-affinity, selective, self-assembling binding motifs. Photocontrol of coiled-coil self-assembly offers precise localization of their activity. This study prepared three azobenzene-containing amino acids and incorporated them into a model coiled coil. The results showed that the presence of these amino acids affected coiled-coil binding strength and folding, with the size of the amino acid having an impact on photoisomerization. Molecular dynamics simulations supported the hypothesis that the positioning of the diazene group and reduction of amino acid rotations influenced coiled-coil assembly. This strategy of using photoswitchable amino acids shows potential for controlling biomaterial assembly.

Summary: An ideal nanomedicine system improves drug therapy by enhancing cellular uptake. However, current nanomedicines mainly enter cells through endosomal/lysosomal pathways, leading to inefficient delivery of therapeutic cargo. To overcome this issue, the authors developed a synthetic lipidated peptide pair, E4/K4, inspired by natural fusion machinery. By optimizing the structure of the peptide, the researchers achieved enhanced membrane fusion and efficient delivery of drugs into cells. This study provides valuable insights for the development of efficient drug delivery systems based on liposome-cell fusion strategies.

Summary: Pancreatic adenocarcinoma (PDAC) is difficult to treat with chemotherapy and has a poor survival rate. Targeted drug delivery approaches using mesoporous silica nanoparticles (MSNs) have shown promise in killing PDAC cells in vitro. However, when tested in clinically relevant models, off-target toxicity was observed. Optimized ADAM9-responsive MSNs (OPT-MSNs) were developed to minimize off-target cytotoxicity while still efficiently killing PDAC cells. In a preclinical PDAC xenograft model, paclitaxel-loaded OPT-MSNs reduced organ damage and leukopenia but did not exhibit antitumor activity. This study highlights the challenges in translating MSN-based tumor-targeting strategies into effective clinical treatments.

Summary: There is a growing interest in using metal-organic cages (MOCs) in the field of biomedicine due to their unique distribution in organisms and novel cytotoxicity mechanisms. However, the stability of many MOCs under in vivo conditions hinders their study in living cells. In this study, the toxicity and photophysical properties of stable rhodamine-functionalized platinum-based Pt2L4 nanospheres and their building blocks are investigated in vitro and in vivo. The results show that the Pt2L4 nanospheres exhibit reduced cytotoxicity and altered biodistribution compared to the building blocks in zebrafish and human cancer cell lines. These findings provide a basis for the application of MOCs in cancer therapy.

Summary: Membrane fusion is crucial for life and can be studied using artificial fusion peptides. This study investigated the efficiency and kinetics of two fusion peptides, CPE and CPK, using TIRF microscopy. The authors found that the fusogenic facilitation of CPE and CPK in liposomes is dependent on the particle size, and CPK alone can facilitate membrane fusion in certain conditions. These findings provide insights into peptide-mediated membrane fusion and have implications for drug delivery systems.
