Background To investigate the recurrent stroke types associated with white matter lesions (WMLs), we prospectively observed recurrences in patients with histories of lacunar infarctions (LIs). Methods We prospectively analyzed the types of stroke rec

Based on electron-beam direct writing on the SiOx/Si substrates, favorable absorption sites for ferric cations (Fe3+ ions) were created on the surface oxide layer. This allowed Fe3+-assisted self-assembled arrays of single-wall carbon nanotube (SWNT)

Single-wall carbon nanotube (SWNT) nanofibrils were assembled onto conductive atomic force microscopy (AFM) probes with the help of dielectrophoresis (DEP). This process involved the application of a 10 V, 2 MHz, AC bias between a metal-coated AFM pr

In this work, we show the use of single stranded DNA aptamers as selective biorecognition elements in a sensor based on a field effect transistor (FET) platform. Aptamers are chemically attached to the semiconducting material in the FET through the u
