A woman once came to know about a dua to make someone fall in love. She said that dua, blew into the water and gave the water to a man to drink to make him fall in love with her. She understood that she has done the wrong thing and she asked forgiveness from Allah. Now whatever she has done, does it make marriage between the above man and the woman prohibited in this world and in Jannah?

You should note that correspondence and contact between the sexes is one of the doors that lead to fitnah (temptation). Sharee’ah is filled with evidence which indicates that it is essential to beware of falling into the traps of the shaytaan in this matter.
When the Prophet صلي الله عليه وسلّم saw a young man merely looking at a young woman, he turned his head so as to make him look away, then he said: “I saw a young man and a young woman, and I did not trust the shaytaan not to tempt them.”(Tirmidhi)
This does not mean that it is haraam for a man or woman to like a specific person whom he or she chooses to be a spouse, and feel love for that person and want to marry them if possible. Love has to do with the heart, and it may appear in a person’s heart for reasons known or unknown. But if it is because of mixing or looking or haraam conversations, then it is also haraam.
If love develops for a reason that is not haraam, a person cannot be blamed for that, such as one who loves his wife or his slave woman, then he leaves her but that love remains and does not leave him. He is not to be blamed for that.
In regards to your query and question; there is nothing that has invalidated the Nikah or Marriage, they are still husband and wife.
Only Allah knows best
