This chapter aims to show significant progress that our group has been developing and the applications of several doped semiconductor nanocrystals (NCs), as nanopowders or embedded in glass systems. Depending on the type of dopant incorporated in the nanocrystals, the physical, chemical, and biological properties can be intensified. However, it can also generate undesired toxic effects that can potentially compromise its use. Here we present the potential of zinc oxide NCs doped with silver (Ag), gold (Au), and magnesium (Mg) ions to control bacterial diseases in agriculture. We have also performed biocompatibility analysis of the pure and Ag-doped sodium titanate (Na2Ti3O7) NCs in Drosophila. The doped nanocrystals embedded in glassy systems are chrome (Cr) or copper (Cu) in ZnTe and Bi2Te3 NCs for spintronic development nanodevices. Therefore, we will show several advantages that doped nanocrystals may present in the technological and biotechnological areas.

The incorporation of nanoparticles into sensors or with antimicrobial and fertilizer properties in agriculture signifies a paradigm shift toward accuracy and sustainability. This chapter shows the numerous uses of nanoparticles and nanoparticle-based sensors in agribusiness. Their innovative contribution to promoting eco-friendly practices is examined. A bounty of advancements that maximize yields and contribute to a sustainable agricultural future is promised by these bactericidal nanoparticles, sensor technologies, and enhanced fertilizers, which sow the seeds of creativity. The discussion explores the potential of nanoparticles to transform farming practices, diminish environmental harm, and cultivate a progressive, eco-conscious farming landscape. Nanoparticle-based sensors provide data for informed decision-making, bactericidal nanoparticles protect crops from harmful pathogens, and nanotechnology enhances fertilizers for nutrient delivery and plant uptake.
