Researchers have explored ways to deliver micronutrients like magnesium and vitamin D3, but issues such as slow hydration and poor water compatibility have limited progress. At the same time, pollutants like lead and 2,4-DCPh pose serious health risks, and conventional removal methods are often costly or unsustainable. Thus, there is a need for safe, eco-friendly, and cost-effective adsorbents to protect public health. This study aims to fabricate starch nanomaterials (SNM) as an effective nanocarrier for VD3 and Mg+2, and as a nano-detoxicant for Pb and 2,4DCPh.
