“…These biomolecules interact with particles and encapsulate them to form a layered structure termed an ecocorona, which can alter the particles’ physiochemical properties, interaction fate, and effects in the environment. The ecocorona on particulate plastics can vary in size and chemical composition, which is mainly attributed to the abundance and physiochemical properties of both the biomolecules and plastic particles, as well as the water chemistry in which they are suspended . While each of these species has a different structure, charge, and carbon content, in the context of 12 C measurement by sp-ICP-TOFMS, the relevant aspect is the elevated dissolved carbon background in solution.…”

Multiple analytical techniques to measure microplastics (MPs) in complex environmental matrices are currently under development, and which is most suited often depends on the aim(s) of the research question and the experimental design. Here, we further broaden the suite of possible techniques which can directly detect MPs in suspension while differentiating the carbon contained in MPs from other natural particles and dissolved organic carbon (DOC). Single particle inductively coupled plasma mass spectrometry (sp-ICP-MS) is well suited to measuring particles at trace concentrations, and the use of ICP time-of-flight-MS (ICP-TOFMS) allows one to simultaneously monitor the entire elemental spectrum to assess the full elemental composition of individual particles through developing elemental fingerprints. Because carbon is not detected in a standard operation mode with icp TOF, a dedicated optimization was necessary. Subsequently, to assess the feasibility of monitoring 12C particle pulses for the detection of MPs in more complex natural waters, two proof-of-principle studies were performed to measure MPs in waters with environmentally relevant DOC backgrounds (≤20 mg/L) and in the presence of other carbon containing particles, here, algae. Elevated DOC concentrations did not impact the enumeration of particles in suspension, and individual MPs, single algae, and aggregates of MPs and algae were clearly distinguished. The simultaneous identification of different analytes of interest allows for multiplexed sp-ICP-TOFMS experiments utilizing elemental fingerprinting of particles and is a step forward in quantifying MPs in aqueous environmental samples.

“…116 These interactions lead to the formation of different types of biomolecular layers on the surface of NPs that alter the aggregation, solubilization, and attachment behavior of the particles, and ultimately their bioaccumulation. 116,117 Moreover, unbound NOM can compete with NPs for internalization receptors on the cell surface, thus affecting the interactions between cells and NPs. 116 Previous studies have suggested that the acid-base interactions between the organic acid groups present in humic acid and the hydroxyl groups on the surface of SiO 2 NPs promote the adsorption of humic acid onto SiO 2 NPs.…”

“…NPs toxicity, i. e., nanotoxicity, is an ever‐growing concern due to the extensive use of NPs in modern industries and the poor recyclability of nanomaterials. For instance, the degradation of plastics to micro‐ and nano‐sized plastics is an infamous case study of the immediate and adverse effects imposed by unsupervised human waste that is polluting the seas and water sources [11–15] . However, nano‐plastics are merely one example out of countless nanomaterials that continuously threaten living organisms.…”

Nanoparticle (NP) toxicity is a severe environmental threat that calls for the development of novel field-effective platforms for NP detection and speciation according to their physicochemical properties. In this regard, nanoparticle-imprinted matrix (NAIM) is an innovative approach that enables the selective detection of NPs by their size, shape, surface chemistry, and composition. However, thus far, NAIM systems have mainly been used for detecting metallic NPs such as Au or Ag by electrochemical dissolution. Herein, we show that a facile electrochemical detection of non-conductive silica-NPs can be achieved by the NAIM approach. Specifically, the physical blocking of nanocavities was indirectly monitored by recording the redox activity of hexacyanoferrate(III) inside the nanocavities following exposure to silica-NPs using cyclic voltammetry (CV) and square wave voltammetry (SWV). This approach was examined for two different matrices based on phenol and 3-aminophenol monomers. Notably, we observed a dissimilar redox activity of hexacyanoferrate(III) upon reuptake, pointing to the importance of molecular interactions in NPs recognition. In addition, highspatial-resolution vibrational mapping was conducted by IR scattering-type scanning near-field optical microscopy (IR-sSNOM) imaging to characterize the physical entrapment of silica-NPs by the matrix in the nanoscale.
