An assortment of plastics was selected to represent typical micro- and nanoplastic types, including polyolefins, polyesters, and polyamides, featuring assorted structural motives (see Figure S1 for structures) [1 ]. The microplastics polyethylene (PE), polyethylene terephthalate (PET), polyvinylidene dichloride (PVDC), and polyamide (Nylon 12, PA) were procured from Goodfellow (Hamburg, Germany) as dry powders. Polystyrene (PS) nanoplastic particles (100 nm particle size standard) were obtained in the form of an aqueous suspension from Thermo Scientific (Bremen, Germany). The fluorescent dyes acridine orange (hydrochloride), rhodamine 6G, rhodamine B, fluorescein (disodium salt), and eosinY (disodium salt) were purchased from Magnacol Ltd. (Newtown, UK) (see Figure S2 for structures). The porphyrin derivatives TPP, copper(II), vanadate, and zinc tetraphenylporhyrins (Cu-TPP, V-TPP, Zn-TPP), along with tetrahydrofuran (THF), ethanol, 1-octanol, pluronic surfactant, and Cu(OAc)2, were acquired from Sigma Aldrich (Darmstadt, Germany). All chemicals were used as received. 64Cu was produced at the in-house cyclotron at the HZDR Research Site Leipzig [42 (link)].
Pluronic surfactant
Manufactured by Merck Group
Pluronic surfactants are a class of non-ionic block copolymers composed of polyethylene oxide (PEO) and polypropylene oxide (PPO) blocks. They exhibit unique properties, such as temperature-dependent solubility and the ability to self-assemble into micelles, making them useful in various applications, including as emulsifiers, solubilizers, and drug delivery agents.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
