Delivery of luminescent particles to plants for information encoding and storage.

ABSTRACT: In the era of smart agriculture, the precise labeling and recording of growth information in plants pose challenges for modern agricultural production. This study introduces strontium aluminate particles coated with H₃PO₄ as luminescent labels capable of spatial embedding within plants for information encoding and storage during growth. The encapsulation with H₃PO₄ imparts stability and enhanced luminescence to SrAl₂O₄:Eu²⁺,Dy³⁺ (SAO). Using SAO@H₃PO₄ as a low-damage luminescent label, we implement its delivery into plants through microneedles (MNs) patches. The embedded SAO@H₃PO₄ within plants exhibits sustained and unaltered high signal-to-noise afterglow em
