Summary: Noscapine and its derivatives have shown potential as cough suppressant, anti-cancerous activity, and ability to inhibit the main protease of SARS-CoV-2 and chikungunya. This study focused on designing ionic liquids composed of noscapinium cation with different anions, and analyzing their thermo-chemical data, IR and UV-visible spectra, and ADME behavior. The most soluble and stable ionic liquid among the designed ILs was found to be (R)-5-((S)-4,5-dimethoxy-3-oxo-1,3-dihydroisobenzofuran-1-yl)-4-methoxy-6,6-dimethyl-5,6,7,8-tetrahydro-[1,3]dioxolo[4,5-g]isoquinolin-6-ium trifluoromethanesulfonate (IL4) based on DFT calculations.

Summary: In mammalian cells, cyanide exhibits a biphasic effect on mitochondrial Complex IV activity, stimulating it at low concentrations and inhibiting it at higher concentrations. Low levels of cyanide lead to increased cell proliferation and ATP production, while higher levels result in inhibition of cellular bioenergetics. The presence of cyanide-producing enzymes in mammalian cells suggests a regulatory role for endogenous cyanide.

Summary: Scattering-based light-sheet microscopy has become an important technique in label-free tissue imaging and cellular morphometry, but achieving subcellular resolution remains a challenge. In this study, we addressed this by using time-averaged pseudo-thermalized light-sheet illumination, which allowed us to achieve subcellular resolving power after image deconvolution. We successfully validated this approach by imaging cytosolic carbon depots in yeast and bacteria with increased specificity, no staining, and ultralow irradiance levels. This scattering-based light-sheet microscopy approach has the potential to advance single, live cell imaging by reducing phototoxicity.

Summary: Ionic liquids (ILs) are currently attracting researchers due to their potential applications in various fields. In biomedical research, understanding the interactions between ILs and cellular membranes, mimicked with lipid bilayers and monolayers, is crucial. Among the three imidazolium-based ILs studied, [DMIM][BF4] showed the strongest interaction with liver lipid membranes. This interaction is mainly driven by entropy and results in ILs penetrating the core of lipid bilayers. Dynamic light scattering (DLS) measurements suggest that [DMIM][BF4] does not affect the stability of lipid vesicles, while X-ray reflectivity (XRR) measurements reveal a concentration-dependent change in monolayer structure.

Summary: Low toxicity is a crucial property for the sustainable use of polyethylene glycol-based deep eutectic solvents (PEG-based DESs) in various fields. However, the specific toxicity of PEG-based DESs has not been reported, and guidelines for reducing toxicity need to be explored. This study evaluated the cytotoxicity of several PEG-based DESs against lung cancer cells (A549) and proposed strategies for minimizing toxicity, such as adjusting mole ratio, hydrogen-bonding donor, hydrogen-bonding acceptor, components numbers, and solvent concentration. The results showed that DESs are more toxic than their individual components, generally following the toxicity order of the individual components, except for the hydrogen-bonding donor. This research offers potential approaches for reducing the toxicity of DESs in sustainable and green chemistry.

Summary: Lipid bilayers are essential for cell membranes and have potential applications in bio-nanotechnology. This study focuses on the absorption of ionic liquids (ILs) into lipid bilayers and found that IL cations are absorbed in all phases of the lipid bilayer, with the amount of IL insertion increasing with temperature. The observed temperature trend can be explained by the entropy gain from IL hydration water. The ability to control IL absorption with temperature can be utilized to modulate the effect of ILs on biomembranes in bio-nanotechnological applications.

Summary: Cell dissemination is a key characteristic of cancer metastasis, and studying this process in vitro can provide insights into the mechanisms and therapeutic responses. The orientation of fibrillar collagen plays a crucial role in cell migration, and reproducible assays are needed to understand how cells migrate on aligned collagen fibrils. In this study, a spheroid-based migration assay integrated with a fibrillar type I collagen matrix was used to quantify the migration of osteosarcoma cells. The results showed polarized cell dissemination with increased invasion in the direction of fibril alignment.

Summary: Molecular dynamics simulations were used to investigate the effects of phosphonium cations and geminal dications on the hydration layer of phospholipid bilayers. The results showed that at high concentration, the ions became absorbed into the lipid phase, leading to changes in the properties of the lipid bilayer. The absorption kinetics were found to be different for cations and dications, with cations being absorbed faster than dications.

Summary: Since the discovery of piezoelectricity in bone in 1957, there has been a debate about the functional role of collagen piezoelectricity. The investigation of piezoelectricity in collagen has generated interest in bone remodeling, but there are conflicting reports about its presence in a humid environment. This study used lateral piezoresponse force microscopy to investigate the electromechanical properties of type I collagen from a rat tail tendon at the nanoscale, and found that collagen retains its piezoelectric behavior even in a biologically relevant humidity range.

Summary: In this study, we demonstrate the fabrication of micropillar arrays using a combination of direct laser writing and nanoimprint lithography. By using two diacrylate monomers, polycaprolactone dimethacrylate (PCLDMA) and 1,6-hexanediol diacrylate (HDDA), we were able to create copolymer formulations that could be controllably degraded in the presence of base. The topography of the micropillars could be varied over a short period of time, and their degradation was attributed to the presence of PCL. These materials showed compatibility with mammalian cells, making them potentially useful for biomedical applications in microfabrication contexts.

Summary: Peptide self-assemblies have attracted increasing interest due to their intriguing and tunable physicochemical properties, but their applications are limited by their micro/nano-scale dimensions. To overcome this limitation and realize the practical utilization of bio-organic super-architectures, researchers have focused on peptide microfabrication to integrate the properties of individual supermolecules and create higher-level organizations for functional devices. This review summarizes the recent advancements in peptide microfabrication, discussing various methodologies, properties, and applications of engineered peptide large-scale, highly-ordered organizations. The current limitations of microfabrication strategies are also critically evaluated, and alternative solutions are proposed.
