Interactions of paramagnetic metal complexes with their biological environment can modulate magnetic resonance imaging (MRI) contrast–enhancing properties in different ways, and this has been widely exploited to create responsive probes that provide biochemical information. We survey progress two rapidly growing areas: the MRI detection biologically important ions, such as calcium, zinc, copper...

Maize is a high nutrient demanding and zinc responsive crop. A Field study was conducted at farmer’s field, Pavali village of Viruthunagar district during 2019-2020 to evaluate the effect chelated fertilizer on growth parameters maize (Zea mays L.). The experiment laid out as randomized block design with five replication. results showed that plant height (192.5 cm), leaf length (80.4 breadth (9...
