Hey bioman, this novel might fit the bill: Afterparty by Darryl Gregory.
It's set in a futuristic world where drugs can be printed. Any drug, you name it, they can print it. It involves a scientist and a pill she and a group of friends created, highly successful, but dangerously results in hallucinations (some disagree) of godly figures and feelings of transcendence. It's also highly addictive. They scrapped the project, but mysteriously it has turned up on the streets again. The antagonist is one of the members of the original research group, but no one knows which member.
It deals with medicine, involves a scientist as a protagonist, involves a mysterious antagonist who foils the protagonist at every turn, and involves futuristic medical tech that is the catalyst and central to the whole story. What do you think? Is it a Biotech thriller?
I love the book and would recommend it.
