Orally dispersible films (ODFs) prepared by an electrospinning are a novel type of pharmaceutical formulation. This dosage form has the potential to be beneficial for small children and the elderly, who can have problems with administration of classical tablets due to the increased risk of choking and difficulty with swallowing. Due to the highly porous nanofiber morphology, the ODFs examined in this study achieve rapid disintegration into drug microparticles when in contact with saliva. The suspension is then easier to swallow. In this study, we focus on the impact of film composition (polymer matrix composition) on the properties of electrospun membranes. In particular, we prepared ODFs composed of a mixture of PEG 100 000 with HPMC E5 and PVP k90 with HPMC E5. We found significant differences in the structure of electrospinned membranes, where samples containing PEG 100 000 and HPMC E5 exhibited much narrower distribution of fibers. Furthermore, nanofibers containing PVP k90 exhibit a faster disintegration rate, while dissolution of the drug was faster in the case of PEG 100 000 containing ODFs. The improvement was caused by both the structure and composition of the membranes.

Article Synopsis
  • The study highlights the rising importance of assessing the cytotoxicity of gold nanoparticles (GNPs) in biomedical applications.
  • Researchers synthesized three types of GNPs—gold nanorods (GNRs), gold nanobipyramids (GNBPs), and gold nanocups (GNCs)—using a specific method and measured their sizes.
  • The experiments showed that the cytotoxic effects of GNPs varied based on their shape and surface coating, with CTAB-coated GNPs being more harmful than PEG-coated ones, indicating that these factors significantly influence GNP behavior in cells.

Membrane alterations are among central factors predetermining cell survival during cryopreservation. In the present research, we tested some serum-/xeno-free cryoprotective compositions including dimethyl sulfoxide (MeSO) and polymers for their osmotic impact and toxicity towards testicular interstitial cells (ICs). IC survival was determined after their contact with MeSO, dextran (D40), hydroxyethyl starch (HES), polyethylene glycols (PEG1500 and PEG400), or after cryopreservation and cryoprotective agent (CPA) removal.

Inkless paper made from photochromic materials has garnered significant interest owing to its potential to reduce both ink and paper pollution during production. In this research, we synthesized a dual-material film (EC-PVP/PGMEA/PMoA) and conducted a detailed investigation of its photochromic response to visible light and its microstructural properties. Initially, the film appeared as a translucent yellow, but upon exposure to visible light, it shifted to blue with a maximum absorption peak of 2.

Pain and inflammation are common symptoms of a majority of the diseases. Chronic pain and inflammation, as well as related dreadful disorders, remain difficult to control due to a lack of safe and effective medications. In this work, biocompatible platinum nanoparticles with significant analgesic and anti-inflammatory action were synthesized through a wet chemical method using polyethylene glycol-400 as a capping agent and sodium borohydride as a reducing agent.
