Dear Forum Members,

 I am working on a DPD simulation involving a silica surface and a polymer chain within a cell in Materials Studio. Both the silica surface and the polymer chain have been converted into bead models. My goal is to graft the polymer onto the silica surface by forming a bond between the last bead of the polymer chain and one bead of the silica glass surface.

However, I have not been able to find a method to create this bond in the system. 

I would be very grateful for any advice or support you can provide.

Thank you very much for your time and help!
