Review: Application Of LIBS To Elemental Analysis And Mapping Of Plant Samples

Abstract

Trace minerals and metallic elements play a key role in plant metabolism and function. Therefore, it is important to understand the movement and distribution of trace minerals within various parts of plants in order to understand their metabolic pathways. Information on the localization of minerals can be utilized in the fields of plant science, agriculture, and food technologies. In this context, herein, we review the feasibility of application of laser-induced breakdown spectroscopy (LIBS) as a technique for trace element detection and mapping in different plant matrices. LIBS is a well-established technique that can be used to perform rapid multi-elemental detection in various types of samples, including plants. Owing to the unique capabilities of LIBS, its field applications are growing rapidly, particularly in the area of plant science. Here, our primary emphasis is on the quantitative and qualitative elemental imaging of different varieties of plant species that are of importance as medicines and foodstuffs. In this review article, we present an exhaustive survey of recent developments, including technical advances and recent work involving the detection of nanoparticles in plant samples and in the monitoring of soil content. The future potential of LIBS and the viability of its possible applications to the detection of essential minerals and heavy metals in plants used as foods or of medicinal importance are also discussed.

The Role of Silica Nanoparticles in Promoting the Germination of Tomato (Solanum lycopersicum) Seeds

“…Internal elements in plants ( Figure 3 ) can be indicators of the influence of the surrounding environment on plant growth. Every environmental change that occurs can change the composition and abundance of these elements [ 52 ]. Lin and Xing concluded that ZnO nanoparticles at an initial concentration of 2000 mg/L were toxic [ 31 ].…”

A Progress Review On Characterization, Environmental Behaviors And Toxicity Effects Of Micro (Nano) Plastics Using Atomic Spectrometry

“…It can provide the chemical composition and information on molecular structure of the samples and the analysis can also be completed in only a few seconds. 61 Another advantage of this method is the possibility of real time characterization of the samples which is convenient to re-collect the sample if there is a problem. Previous studies have shown that LIBS can be used to distinguish plastics from natural materials and identify the types of basic polymers, especially in distinguishing C-O and C-C skeleton, PE, and PP particles.…”

A novel strategy for quantitative analysis of the energy value of milk powdervialaser-induced breakdown spectroscopy coupled with machine learning and a genetic algorithm

“…Laser-induced breakdown spectroscopy (LIBS) is a rapidly developing chemical element analysis technology that has been widely used in the detection of alloys, 5–7 plant materials, 8–10 food and nutrition, 11–13 rocks, 14–16 and soils. 17–19 As a fast, online, pollution-free, and low-cost technology, it is well suited for the approximate analysis of milk powder.…”
