Summary: In this study, we utilized solvent vapor annealing as a polymer processing method to condense a large amount of solvent vapors onto thin films of block copolymers, promoting their self-assembly into ordered nanostructures. Atomic force microscopy revealed the successful generation of a periodic lamellar morphology of poly(2-vinylpyridine)-b-polybutadiene and an ordered morphology comprised of hexagonally-packed structures made of poly(2-vinylpyridine)-b-poly(cyclohexyl methacrylate) on solid substrates.

Summary: This study presents the first systematic investigation on the thermodynamics of protein immobilization in metal-organic frameworks (MOFs). It demonstrates that MOFs provide a hydrophobic stabilizing microenvironment for proteins, leading to an entropically driven encapsulation process. Among a series of Zr-MOFs, pyrene-based NU-1000 exhibits the most favorable encapsulation process for insulin.

Summary: This research paper examines the issues associated with power compensation isothermal titration calorimetry, highlighting the possibility of obtaining different enthalpy values with different instruments and setting parameters. It emphasizes that modern calorimeters' dynamic power compensation mode may lead to overcompensation of heat effects, resulting in experimental results heavily reliant on chosen parameters. To avoid these problems, the paper suggests checking raw signals and conducting experiments with low or disabled power compensation when observing switching effects.

Summary: DNA can self-assemble into superstructures at nanometer to micrometer scales. In this study, we demonstrate the assembly of DNA nanosheets using a flexible DNA unit that is designed to have a shape resembling a Feynman diagram. The nanosheets can be assembled at solid/liquid and liquid/liquid interfaces and exhibit different properties based on their thickness and coverage. This research paves the way for the controlled assembly of reconfigurable/responsive nanosheets and membranes that can be potentially used in studying biomechanical processes and materials transport.

Summary: This study investigates the structure and correlations between structure, mechanical, and biological properties of gelatin-based materials. Gelatin electro-spun materials have higher content of ordered structure compared to gelatin casted films, which may be attributed to the random coil - alpha-helix transition during electrospinning. The presence of cross linker (GPTMS) decreases the ordered structures in gelatin casted films, while it does not affect the percentage of ordered structure in electrospun samples. The presence of keratin in gelatin/keratin electrospun biomaterials decreases alpha-helix content and promotes the conversion from antiparallel to parallel beta-sheet.

Summary: In this study, we investigated the assembly and drug release behavior of a drug delivery nanocarrier using reactive molecular dynamics simulations. Our results show that the assembled nanotool composed of ZnO nanoparticles, oleic acid chains, and a drug called carfilzomib is stable in ethanol. However, when immersed in water, the size of the assembly increases, causing the lipids to swell and potentially release the drug cargo.
