Hi,
Thanks for your reply.
I understand that a past participle preceding a noun functions as an adjective.
However, to my understanding, both present and past participles following a noun functions as an adjective as well. But the difference is that the present participle is used if and only if the modified noun can "do" the action; on the hand, the past participle is used if and only if the modified noun is the object of the "action".
For examples,
The guy bit by the dog is in the hospital now. <- the guy was bit by a dog.
The guy biting the dog is in the police station now. <- the guy bit a dog.
Similarly, if "targeted" in this OG question is in a past participle form, then doesn't it imply that each of the antibodies are targeted specifically at an invading microbe or foreign substance? I thought that the sentence wants to express: each of the antibodies targets specifically at an invading microbe or foreign substance.
An antibody cannot BE targeted at something, right?
Thanks in advance.
