For this purpose, we delve into the theoretical and practical foundations of CMD, emphasizing its novel contributions and unique features relative to existing methods, whilst acknowledging its current limitations. Broadly, the application of CMD across various fields offers novel perspectives on numerous physicochemical processes, previously constrained in in silico studies by limitations of finite system sizes. In this setting, CMD stands apart as a general-purpose methodology, promising to be an exceptionally useful simulation tool for exploring concentration-driven phenomena at the molecular scale.

Owing to their outstanding biocompatibility, biodegradability, structural stability, diverse functionalities, and environmental friendliness, protein-based nanomaterials have a wide range of applications in the biomedical and bionanotechnological industries. In the realm of pharmaceutical applications, including drug delivery, cancer treatment, vaccinations, immunotherapies, biosensing, and biocatalysis, they have commanded considerable attention. Despite the mounting evidence of antibiotic resistance and the proliferation of drug-resistant microbes, the field currently lacks unique nanostructures capable of fulfilling their potential as next-generation antibacterial agents. Herein, the discovery of engineered protein-based supramolecular nanostructures, termed protein nanospears, is detailed, featuring well-defined shapes, geometries, and architectures, while demonstrating remarkable broad-spectrum antibacterial effectiveness. Self-assembly procedures, either spontaneous cleavage-dependent or precisely regulated, are used to engineer protein nanospears employing mild metal salt ions (Mg2+, Ca2+, Na+) as molecular instigators. Across their multitude, the nanospears' dimensions encompass the entire spectrum from nano- to micrometer scales. Protein nanospears display a remarkable thermal and chemical stability; however, this stability is compromised by rapid disassembly when exposed to high concentrations of chaotropes exceeding 1 mM sodium dodecyl sulfate (SDS). Via the synergistic effects of biological assays and electron microscopy, nanospears' nanostructure and enzymatic action cause rapid and irreparable damage to bacterial morphology; this distinctive action mechanism sets them apart from traditional antibiotics. These protein nanospears show great potential in combating the growing threat posed by resistant bacteria, motivating the creation of other antibacterial protein nanomaterials with a variety of structural, dimensional, and functional properties.

A new series of C1s inhibitors, non-amidine in nature, have been the focus of study. To enhance C1s inhibitory activity, while preserving selectivity against other serine proteases, the high-throughput screening hit 3, which featured isoquinoline, was modified to include 1-aminophthalazine. Disclosing the crystal structure of C1s bound to a small-molecule inhibitor (4e) marked our initial step. Leveraging this structure, we performed structure-based optimization of the S2 and S3 sites, significantly enhancing C1s's inhibitory activity by over 300-fold. The introduction of fluorine at the 8-position of 1-aminophthalazine led to improved membrane permeability, culminating in the discovery of (R)-8 as a potent, selective, orally available, and brain-penetrating C1s inhibitor. In an in vitro assay, (R)-8 exhibited a dose-dependent suppression of membrane attack complex formation, triggered by human serum, thus validating the efficiency of selective C1s inhibition in blocking the classical complement pathway. For this reason, (R)-8 has demonstrated itself to be a valuable tool compound, useful in both in vitro and in vivo experiments.

Utilizing polynuclear molecular clusters, new hierarchical switchable materials with collective properties can be designed by adjusting the chemical composition, size, shapes, and overall organization of their constituent building blocks. In a study on novel materials, researchers strategically synthesized and structurally analyzed a sequence of cyanido-bridged nanoclusters. These include FeII[FeII(bzbpen)]6[WV(CN)8]2[WIV(CN)8]2•18MeOH (1), NaI[CoII(bzbpen)]6[WV(CN)8]3[WIV(CN)8]2•8MeOH (2), NaI[NiII(bzbpen)]6[WV(CN)8]3[WIV(CN)8]2•7MeOH (3), and CoII[CoII(R/S-pabh)2]6[WV(CN)8]2[WIV(CN)8]2•6MeOH [4R and 4S; bzbpen = N1,N2-dibenzyl-N1,N2-bis(pyridin-2-ylmethyl)ethane-12-diamine; R/S-pabh = (R/S)-N-(1-naphthyl)-1-(pyridin-2-yl)methanimine] specimens, reaching sizes up to approximately 11 nm3. Numbers 20, 22, and 25 nanometers (1 to 3) roughly. The 14, 25, 25 nm (4) structure exhibits site-specific spin state and transition preferences, mediated by subtle exogenous and endogenous effects on similar yet diverse 3d metal-ion coordination entities. The mid-temperature-range spin-crossover (SCO) characteristics of sample 1 are more advanced than those observed in previously reported octacyanidometallate-based SCO clusters. The SCO transition commences near room temperature. The latter feature is observed in compounds 2 and 4, suggesting the appearance of a CoII-centered SCO not reported in prior studies of bimetallic cyanido-bridged CoII-WV/IV systems. The reversible switching of the SCO behavior in 1, via a single-crystal-to-single-crystal transformation occurring during desolvation, was also reported.

For the past decade, DNA-templated silver nanoclusters (DNA-AgNCs) have been extensively studied, largely due to the desirable optical characteristics they exhibit, namely efficient luminescence and a considerable Stokes shift. Nevertheless, the dynamic features of these systems in their excited states are not well understood, because studies on the mechanisms that lead to fluorescence are infrequent. In this investigation of the 16-atom silver cluster (DNA-Ag16NC), we focus on the early time relaxation processes characterized by near-infrared emission and a substantial Stokes shift exceeding 5000 cm-1. By combining ultrafast optical spectroscopies, we investigate the photoinduced dynamics of DNA-Ag16NC, spanning temporal regimes from tens of femtoseconds to nanoseconds, and then develop a kinetic model that clarifies the underlying physical picture of the photoinduced phenomena. Our expectation is that the resulting model will contribute to guiding research endeavors toward understanding the electronic structure and behavior of these novel substances, and their potential applications in fluorescence-based labeling, imaging, and sensing.
