Nanoparticle transport into plants is an evolving field of research with diverse applications in agriculture and biotechnology. This article provides an overview of the challenges and prospects associated with the transport of nanoparticles in plants, focusing on delivery methods and the detection of nanoparticles within plant tissues. Passive and assisted delivery methods, including the use of roots and leaves as introduction sites, are discussed, along with their respective advantages and limitations. The barriers encountered in nanoparticle delivery to plants are highlighted, emphasizing the need for innovative approaches (e.g., the stem as a new recognition site) to optimize transport efficiency. In recent years, research efforts have intensified, leading to an evendeeper understanding of the intricate mechanisms governing the interaction of nanomaterials with plant tissues and cells. Investigations into the uptake pathways and translocation mechanisms within plants have revealed nuanced responses to different types of nanoparticles. Additionally, this article delves into the importance of detection methods for studying nanoparticle localization and quantification within plant tissues. Various techniques are presented as valuable tools for comprehensively understanding nanoparticle–plant interactions. The reliance on multiple detection methods for data validation is emphasized to enhance the reliability of the research findings. The future outlooks of this field are explored, including the potential use of alternative introduction sites, such as stems, and the continued development of nanoparticle formulations that improve adhesion and penetration. By addressing these challenges and fostering multidisciplinary research, the field of nanoparticle transport in plants is poised to make significant contributions to sustainable agriculture and environmental management.

Trace evidence analysis is essential in criminal investigations as it provides vital information for establishing connections between suspects and scenes. Minute or complicated trace evidence is sometimes difficult for traditional microscopic techniques to handle. At micro- and nanoscale, electron microscopy (EM) shows great promise as a potent technique for characterization and visualization. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) offer valuable insights into morphology, chemical composition, and crystalline structure of trace evidence, enabling the identification and differentiation of similar materials. TEM allows high-resolution examination of paint components, dirt particles, gunshot residues (GSR), fibers, hair structures, glass shards, nano-particles, explosive materials, etc. In forensic investigations, SEM is a crucial instrument, especially when it comes to GSR analysis, which uses SEM to correlate bullets to firearms more successfully than visual approaches. Additionally, SEM plays a major role in the examination of gemstones and jewelry by identifying manufactured and natural gems, analyzing surface imperfections, and determining elemental compositions. SEM also improves forensic inspection in non-conductive material analysis, paint and fiber analysis, filament bulb investigations, handwriting analysis, and counterfeit detection. The adoption of EM in forensic trace evidence analysis has potential to revolutionize the field, offering valuable insights that were previously unattainable.
