The present invention discloses methods and compositions for imaging nerve cells. The composition comprises a fluorescent dye; And a viral component selected from the group consisting of neurotoxicity, replication-defective virus, viral protein of an oriental virus, and capsid of an oriental virus. Fluorescent dyes alone can not penetrate nerve cells, but when a fluorescent dye binds to a viral component, it can form a dye / viral component complex and penetrate nerve cells. |
