The present invention relates to a neural implant comprising a biomaterial having an outer surface with a stochastic nanoroughness (Rq), and the application of said stochastic nanoroughness in the diagnosis and/or treatment of a neurological disorder, such as, for example, Parkinson's disease, Alzheimer's disease, glioblastoma and/or for disrupting, and/or preventing glial scars in the context of mammalian mechanosensing ion channels selected from the family of PIEZO-1 and PIEZO-2 ion channels.
