Boron is an essential mineral that plays an important role in several biological processes. Boron is required for growth of plants, animals, and humans. There are increasing evidences of this nutrient showing a variety of pleiotropic effects, ranging from anti-inflammatory and antioxidant effects to the modulation of different body systems.

In the FTIR spectra of starch–borax DC hydrogels, with the increase in borax concentration, the peak was changed from 3299 cm −1 to 3278 cm −1. The red-shift phenomenon was caused by the consumption of the hydroxyl groups of corn starch chains to form boron ester bonds with borax.
