“…However, the fibers' internalization, regardless of their composition, can be randomly distributed so that they generate a new roughness according to the different orientations of the fibers [233]. Neurological studies explain that nanofibers can affect cell generation and modify their growth patterns, as observed in neural stem cells [234]. The nanofibers' disposition can affect the neural stem cell elongation and neurite growth in the aligned nanofibers' direction [234].…”

“…The nanofibers' disposition can affect the neural stem cell elongation and neurite growth in the aligned nanofibers' direction [234]. In particular, nanofibers mimic the structure of the fibrous components of the neural extracellular matrix [234]. However, the aggregation is sometimes favorable for reducing the toxicity of individual fibers depending on the local environmental conditions or the assembly in which they are supported, such as those used in reinforcing polymeric matrices that, with the degradation process, can release fibers towards the environment, affecting living beings and the ecosystem [235].…”

Nanotechnology has allowed for significant progress in architectural, artistic, archaeological, or museum heritage conservation for repairing and preventing damages produced by deterioration agents (weathering, contaminants, or biological actions). This review analyzes the current treatments using nanomaterials, including consolidants, biocides, hydrophobic protectives, mechanical resistance improvers, flame-retardants, and multifunctional nanocomposites. Unfortunately, nanomaterials can affect human and animal health, altering the environment. Right now, it is a priority to stop to analyze its advantages and disadvantages. Therefore, the aims are to raise awareness about the nanotoxicity risks during handling and the subsequent environmental exposure to all those directly or indirectly involved in conservation processes. It reports the human–body interaction mechanisms and provides guidelines for preventing or controlling its toxicity, mentioning the current toxicity research of main compounds and emphasizing the need to provide more information about morphological, structural, and specific features that ultimately contribute to understanding their toxicity. It provides information about the current documents of international organizations (European Commission, NIOSH, OECD, Countries Normative) about worker protection, isolation, laboratory ventilation control, and debris management. Furthermore, it reports the qualitative risk assessment methods, management strategies, dose control, and focus/receptor relationship, besides the latest trends of using nanomaterials in masks and gas emissions control devices, discussing their risk of toxicity.
