Hello, first of all thank you for your comment, I'm very grateful to have comments from scientists on this community.
I will take your advice into account. Next time I think I could focus on a concrete topic, like biosensors (for example) from the materials to its applications.
Thank you again.
P.S: I would like to talk to you, could you give me any contact link? Regards

Yeah, sure, check the posts written by @sco for example. Those are written for biologists, be free to write for engineers. Good luck!
