Textile is a necessary commodity and is of paramount importance in a variety of areas. The properties of textiles can be further enhanced and the horizon of their applications can be broadened by the incorporation of nanoparticles using nanotechnology. Nanoproducts ranging from nanofibers, nanocomposite fibers, and intelligent polymeric nanocoatings are frequently incorporated in conventional textiles to provide improved performance and new functionality. Nanocoatings offer numerous specific properties like antimicrobial, wrinkle resistance, and protection against UV radiations. These properties lead to a variety of textile applications, including medicinal textiles and sportswear. In the COVID-19 pandemic situation, nanotechnology has paved the way for need-based customization, such as antiviral masks, PPE kits, etc. This paper provides an overview of the nanomaterials suitable for textile industry, enhancement in the properties of fabrics due to incorporation of nanomaterials, advantages, disadvantages, and a few applications.

“…An example is a study conducted by Lin and Xing (2007), where five nanofertilizers tested on six different crops resulted in opposite effects among crops. Nanofertilizers could negatively impact human health due to their size that, as reviewed by Kalia et al (2019) and Surendhiran et al (2020), enables them to enter the human body through inhalation (Geiser et al, 2017), ingestion through contaminated drinking water and agricultural produce that have accumulated nanomaterials or dermal absorption (Crosera et al, 2009) causing toxicity (Bahadar et al, 2016; Accepted paper Dankers et al, 2018).…”

Highlights- A smart fertilizer allows to control the rate, timing and duration of nutrients release.- Nanofertilizers are powder or liquid formulations which involve the synthesis, design and use of materials at the nanoscale level.- Composite fertilizers are formulations containing nutrients mixed or coated with one or more materials that exploit synergy among materials.- Bioformulations are fertilizers containing active or dormant microorganisms capable to trigger physiological growth responses in plants.- Limited information is available for smart fertilizers on herbaceous crops in open field conditions. Abstract The current agricultural system faces several challenges, the most important being the ability to feed the increasing world population and mitigate climate change. In this context, the improvement of fertilizers’ agronomic efficiency while reducing their cost and environmental impact is one of the biggest tasks. Available literature shows that many efforts have been made to develop innovative fertilizers defined as "smart fertilizers", for which, different interpretations and definitions have been used. This paper aims to define, classify, and describe the new frontier of the so-called smart fertilizers with a particular focus on field-scale studies on herbaceous species. Most of the analyzed papers associate the "smart" concept to the controlled and/or slow release of nutrients, using both terms as synonymous. Some others broadened the concept, including the controlled release of nutrients to reduce the environmental impact. Based on our critical analysis of the available literature, we conclude that a fertilizer can be considered "smart" whenapplied to the soil, it allows control over the rate, timing, and duration of nutrients release. Our new definition is: ‘Smart fertilizer is any single or composed (sub)nanomaterial, multi-component, and/or bioformulation containing one or more nutrients that, through physical, chemical, and/or biological processes, can adapt the timing of nutrient release to the plant nutrient demand, enhancing the agronomic yields and reducing the environmental impact at sustainable costs when compared to conventional fertilizers’.

Silver nanoparticles (NP) offer many applications in the science and technology. Oral delivery of such tiny particles results in enhanced drug absorption, reduction in dose, and minimize adverse effects. This review focuses on the mainly on the effects in the gastrointestinal tract along with its in vitro and in vivo studies carried on the silver NP. In this review, we compiled some of the extensive research in the field of silver NP, highlighting some of the most recent trends in the area. Search was carried in English language using Science direct, PubMed, and Google scholar search engines. The effects of silver NP on gastrointestinal tract such as absorption, distribution, metabolism, and elimination were compiled in this review. In addition, selected in vitro and in vivo studies related to the same are discussed. The accumulation of silver NP leading to Arginia condition also emphasized in the study. Silver NP and herbal silver NP in oral delivery can be exploited for the further safer and effective treatment.
