Research output: Contribution to journalArticlepeer-review


This study explores the feasibility of using surface-micromachining technology for fabricating micro-probes that can be chronically implanted in the brain. The micro-probes were 3 mm long and 50 μm × 2 μm in cross-section. The probes successfully penetrated the brains only when the dura was removed. Chronic implantation of the microprobe for upto 2 weeks produced only minor gliosis.
