General description
Boric acid is a weak monobasic acid, it accepts OH- ions, hence is a Lewis acid. In boric acid, B is sp2 hybridized, forming a planar triangle structure.The principal oxide of boron, B2O3, is obtained as a vitreous solid by dehydration of boric acid at red heat.
Application
•Glass manufacturing: Used in the manufacture of glass fibers to enhance strength and color.
•Ceramics: employed in glazing ceramic wares for improved durability and aesthetics.
•Chemical Intermediate: Acts as a precursor for borates and other boron-based compounds.
•Nuclear Reactors: Utilized as a water coolant and neutron absorber in nuclear applications.
•Electrolytic Capacitors: Used in the production of electrolytic condensers and capacitors.

Boron, an essential micronutrient, is transported in roots of Arabidopsis thaliana mainly by two different types of transporters, BORs and NIPs (nodulin26-like intrinsic proteins). Both are plasma membrane localized, but have distinct transport properties and patterns of cell type-specific accumulation

The human solute carrier (SLC26) family of anion transporters consists of 10 members (SLCA1-11, SLCA10 being a pseudogene) that encode membrane proteins containing ~12 transmembrane (TM) segments with putative N-glycosylation sites (-NXS/T-) in extracellular loops and a COOH-terminal cytosolic STAS

In liquid phase microextraction, high enrichment factors can be obtained using an acceptor phase of small volume. By hanging an acceptor drop at the separation capillary tip, single drop microextraction (SDME) can be in-line coupled with capillary electrophoresis (CE). The
