This systematic review article addresses the impact of nanoparticles on soil ecosystems, particularly within the context of agriculture and environmental sustainability. Both the benefits and risks of nanoparticles in the soil are explored, emphasizing their potential to enhance agricultural productivity, promote plant growth under stress conditions, and contribute to the remediation of contaminated soils. However, the article also examines their ecotoxicological effects, such as damage to soil organisms and disruption of microbial communities, which could compromise soil health and biodiversity. Furthermore, the risks associated with the bioaccumulation of nanoparticles and their interaction with other soil contaminants are discussed. The article underscores the need for further research into the physicochemical properties of nanoparticles and their long-term effects, aiming to guide their responsible use in agricultural and environmental applications.

This systematic literature review addresses the application of nanotechnology to improve the durability of smart textiles in the healthcare sector. The main objective is to identify how nanotechnology has been used to increase the durability of these textiles. The methodology implemented was quantitative and descriptive based on the systematic analysis of the literature, following the PIOC and PRISMA methods. 72 relevant scientific articles published between 2020 and 2024, in English and Spanish, available in the Scopus database were selected. During the analysis, the main challenges were identified regarding the durability of smart textiles, the nanotechnology techniques used, durability indicators and the areas of the health sector where these improved textiles have been implemented. The results reveal that the integration of nanomaterials in smart textiles can provide advanced properties such as greater resistance to abrasion, UV radiation, chemical agents, as well as self-cleaning microbial characteristics, essential for medical applications.

This research work is related to the search for materials that can store a larger amount of heat, because they are necessary to develop accumulator systems that can store heat and use as heat sources required in various activities, since conventional energy sources are increasingly limited or are running out. The high rate of solar radiation in the high plateau region of South America is an advantage to implement heat storage systems, as well as the availability and low cost of the materials with which these systems can be developed, consisting of phase change materials and nanomaterials that have energy absorption properties, others with efficient heat conductivities, which constituted as a single substance, materials with better heat transfer and accumulation properties are achieved, such as paraffin with Silica Gel, Carbon Black and Graphite nanomaterials content. The results achieved by this research are attractive, because the samples of paraffin containing the mentioned nanomaterials can accumulate latent heat of fusion greater than between 20.04 and 31.35%, which can be stored by pure paraffin alone.

The increasing application of nanomaterials across various industrial and scientific sectors has raised significant concerns regarding their potential toxicity, both to human health and the environment. This article presents a systematic review of nanomaterial-induced nanotoxicity, focusing on evaluation methodologies and safety strategies. Relevant studies were collected and analyzed through an exhaustive search of scientific databases, adhering to strict inclusion and exclusion criteria to ensure the quality and relevance of the evidence. The findings highlight the primary mechanisms of toxicity associated with different types of nanomaterials, as well as the most commonly employed analytical tools and experimental models for their assessment. Additionally, emerging approaches to risk mitigation are discussed, including advancements in the design of safer nanomaterials and the development of regulatory frameworks. This work contributes to a comprehensive understanding of nanotoxicity, providing a robust scientific foundation for future research and the safe application of nanomaterials.

In the highland regions, agriculture faces challenges due to factors such as irregular rainfall, temperature fluctuations, and soil erosion, which negatively impact the efficiency of conventionally applied fertilizers and pesticides. This study aims to explore the use of starch nanoparticles (SNPs) as an innovative solution in agriculture, specifically to improve the controlled release of nutrients and pesticides and reduce the ecological impact of inputs. A systematic review was conducted using the PRISMA methodology, where 226 articles were identified, and 9 studies were selected according to inclusion and exclusion criteria. The most reported method for nanoparticle preparation was nanoprecipitation, which allows the production of SNPs with controlled sizes that can encapsulate bioactive substances. Among the relevant results, it was highlighted that SNPs not only improve the efficiency of releasing active compounds such as fatty acids, urea, and phenolic compounds, but also provide greater stability and reduce volatilization. In conclusion, SNPs offer great potential to optimize the use of agricultural resources, providing an ecological and effective alternative for the controlled release of fertilizers and pesticides, which contributes to sustainability and improves agricultural performance in fragile areas.
