Description

General description

Polystyrene is a synthetic thermoplastic, which can find a wide range of applications due to its properties like low cost, rigidity and good processability.

Application

• Polystyrene labware: TEMPO-grafted polystyrene/polymethacrylate organosiloxane Janus nanohybrids are being explored as efficient interfacial catalysts for selective aerobic oxidation, showcasing the application of modified polystyrene in enhancing biotechnological processes (ACS Appl Mater Interfaces, 2024).


• High-impact polystyrene for pharmaceutical packaging: Studies on optical assembly of multi-particle arrays demonstrate the use of polystyrene in creating structured materials that could influence the development of pharmaceutical packaging technologies (Rev Sci Instrum, 2024; ).


• Polystyrene microplates for cell culture applications: The use of polystyrene in solvent-free sample preparations for matrix-assisted laser desorption/ionization time-of-flight mass spectrometry underlines its pivotal role in labware and analytical methods, enhancing the efficiency and accuracy of biochemical assays (Rapid Commun Mass Spectrom, 2024).


• Polystyrene nanoparticles in drug delivery research: The critical parameters for size and concentration determination of nanomaterials emphasize the importance of polystyrene nanoparticles in developing drug delivery systems that require precise and reproducible measurements (Int J Pharm, 2024; ).


• Biocompatible polystyrene for biomedical research: Research into the photonic properties of polystyrene-block-polyvinylpyrrolidone bottle brush block copolymers for creating sustainable and spontaneously emulsified materials showcases polystyrene′s utility in advanced biomedical applications (ACS Macro Lett, 2024;).
