The purpose of the present work was to assess the ability of five new oxicam analogues to interact with the lipid bilayers. To characterize the interaction of newly synthesized NSAIDs (non-steroidal anti-inflammatory drugs) analogues with DPPC lipid bilayers the two following techniques were applied - differential scanning calorimetry (DSC) and fluorescence spectroscopy. The results obtained by these experimental approaches show that new oxicams analogues interact with the lipid model membranes under consideration. As demonstrated both in calorimetric and spectroscopic studies, the greatest influence on the thermotropic properties of the lipid membrane and on the quenching of fluorescence of Laurdan and Prodan was exerted by a derivative named PR47 containing in its structure a two-carbon aliphatic linker with a carbonyl group, as well as bromine and trifluoromethyl substituents.

Extracellular vesicles (EVs) are membranous structures consisting of lipid bilayers that are released by most cell types and serve as important mediators of intercellular communication. The HEK293T cell line model has gained considerable attention from the scientific community, particularly in the fields of engineering and drug delivery. Nevertheless, there is a dearth of systematic comparisons of the most prevalent EV isolation methodologies for HEK293T in terms of recovery and specificity.

Background: Bacillus thuringiensis Cry toxins are well known for their insecticidal properties, primarily through the formation of ion-leakage pores via α4-α5 hairpins. His178 in helix 4 of the Cry4Aa mosquito-active toxin has been suggested to play a crucial role in its biotoxicity.
Objective: This study aimed to investigate the functional importance of Cry4Aa-His178 through experimental and computational analyses.

Phospholipid-derived nanocarriers represent a versatile and chemically customizable class of drug delivery systems that self-assemble into bilayered vesicles due to their intrinsic amphiphilicity. These systems can encapsulate both hydrophilic and hydrophobic drugs through non-covalent interactions and manipulation of lipid phase behavior. This review examines the molecular and supramolecular principles underlying the formation, stability, and functional performance of key phospholipid-based nanocarriers-including liposomes, transferosomes, ethosomes, invasomes, phytosomes, pharmacosomes, and virosomes.

The Martini model is a coarse-grained force field allowing simulations of biomolecular systems as well as a range of materials including different types of nanomaterials of technological interest. Recently, a new version of the force field (version 3) has been released that includes new parameters for lipids, proteins, carbohydrates, and a number of small molecules, but not yet carbon nanomaterials. Here, we present new Martini models for three major types of carbon nanomaterials: fullerene, carbon nanotubes, and graphene.

This study introduces a simple signal transduction system that mimics the receptor tyrosine kinase mechanism by employing amphiphilic receptors embedded in lipid bilayers. The designed receptors carry bisphosphonate head groups and feature aggregation-induced emission enhancement (AIEE) properties. Upon addition of polyammonium messengers, they undergo ligand-induced dimerization or clustering inside the membrane.
