| 摘要 |
In some embodiments, without limitation, the invention comprises a micromachined probe with one or more buried flow microchannels, where at least one of the microchannels is filled with an organic polymer. In some additional embodiments, the invention comprises a micromachined probe having at least a portion of one external surface coated with an organic polymer. The internally or externally applied organic polymer increases the buckling strength of the micromachined probe and decreases the risk of fracture of the probe, or movement or migration of broken fragments, during insertion, use, or removal from biological tissues.
