Yes and no. Kurapica can still use some nen, and it is actually pretty powerful. He is a materialization user by talent, but his eyes give him specialization powers. That is why he was able to use all of the other nen groups. He placed a restriction on the use of his specialization nen, so he can only use the specialization power (and so, the reinforcement chain, the transformation chain, the binding chain, etc) on the Kumo. But he can still use two or three of his chains, on anyone.
