The Zinc Oxide nanoparticles that I synthesized are stable in ethanol but precipitate in water. I need to stabilize stable NPs in water because I want to functionalize antibodies to them.
You need to add hydrophilic stabilizing agents for stability. You may use some of the triblock co-polymers mixture of surfactant to optimize the concentration.

Agreed with Swati Jain, you can use also some short amino acids as dispersant in water
You can use the hydrothermal method, but you must have autoclave vessel
you can use the following method

Single Step Preparation of Regular Zincite Nanospheres Using Cucurbit[7]uril.
It was accepted some time ago. It should be available soon. In water And at room temp.
Try adding Sodium dodecyl sulfate (SDS) to your reaction mixture if you synthesize via a dissolution-based route. you could also try a hydrothermal / Solvothermal synthesis route as suggested by M. Ismail. ZnO NPs can also be pH stabilized in water without needing surfactants. However that might interfere with your subsequent experiments
You can make stable zinc oxide nanoparticles upon functionalization with either surfactants or polyalyl alcohol like polyvinyl alcohol
