Special Issue Information

Dear Colleagues,

The recent advances in nanotechnology have undoubtedly resulted in a rapid and exponential increase in the manufacture and applications of nanoparticles (NPs) and nanomaterial-based products. To date, the requirements for assessing ecological and health risks related to NPs have made clear that the determination of nanoparticles is an emerging field of analytical chemistry. Among the available fractioning, counting and ensemble techniques for sizing and determination of NPs, atomic absorption spectrometry (flame and furnance) and inorganic mass spectrometric systems (e.g., inductively coupled plasma mass spectrometry ICP-MS) are unequivocally at the forefront of noble metals and magnetic NPs analysis. However, due to the increasing demand from the scientific community for analytical information regarding NPs, various emerging techniques, including nano-SIMS and mass cytometry, have been utilized. Although a plethora of instrumental techniques is currently available, various challenges must be addressed to ensure the effective performance of the analytical procedure. Unequivocally, the matrix complexity, as well as the low concentration or heterogeneity of NMs in the sample, are among the limitations that must be addressed by the scientific community. Thus, the determination of NPs poses a significant challenge to analytical chemists. The scope of this Issue is to describe the state of the art and the continuous efforts in analytical methods for nanomaterial determination.

Nanomaterials are materials in which at least one of the three dimensions ranges from 1 to 100 nm, according to the International Organization for Standardization (ISO). Nanomaterials can be categorized according to various parameters, such as their source, their shape, and their origin. Their increasing use in industrial settings, everyday items, electronic devices, etc. poses an environmental and biological risk that needs to be assessed and appropriately addressed. The development of reliable analytical methods for both characterization and quantification of nanomaterials in various matrices is essential. This review summarized the recent trends in analytical methodologies for the characterization and determination of nanoparticles in biological matrices. Full article
