Nano/mikromotorlar, enerjiyi harekete dönüştürme kabiliyetine sahip nano veya mikro boyutta makinalardır. Bunlar; kimyasal yakıt ve harici etkenler neticesinde prensibi ile çalışırlar. Bu etkenler; manyetik alan, elektrik ultrason ışık gibi olabilir. Farklı tahrik mekanizmalarına nano/mikromotorlar kanser bulaşıcı hastalıkların teşhis tedavisinde önemli rol oynarlar. Özellikle tedavilerinde en ...

We present here the construction of a DNA biosensor based on a tubular micromotor that only produces motion-based signal in the presence of DNA target. This "turn on" characteristic of the sensor is achieved by the addition of Pt nanoparticle-DNA conjugate as the motion-inducing catalyst for the micromotors through DNA hybridization. Our work potentially offers new design strategies for motion-...

This paper reviews deposition, integration, and device fabrication of ferroelectric PbZrxTi1−xO3 (PZT) films for applications in microelectromechanical systems. As examples, a piezoelectric ultrasonic micromotor and pyroelectric infrared detector array are presented. A summary of the published data on the piezoelectric properties of PZT thin films is given. The figures of merit for various appl...

This study proposed a rapid prototyping fabrication method for micromotors that allowed us to develop both 1 mm and 1.5 mm diameter permanent-magnet synchronous motors (PMSMs) with an optical rotary encoder. First, an integrated electroforming method was proposed for combining stator housing and flexible print circuit (FPC) coils to ease the manufacturing and assembly of micromotor components. ...

Piezoelectric membranes consisting of sputter deposited PbZrxTi1−xO3 (PZT) films on silicon diaphragms have been investigated for their resonance and piezoelectrical properties, in view of their application as stator of a micromotor. The behavior of resonance frequencies was studied as a function of membrane thickness and dc-bias, in order to derive the total stress in the films and the piezoel...

Here we describe the first example of using self-propelled antibody-functionalized synthetic catalytic microengines for capturing and transporting target proteins between the different reservoirs of a lab-on-a-chip (LOC) device. A new catalytic polymer/Ni/Pt microtube engine, containing carboxy moieties on its mixed poly(3,4-ethylenedioxythiophene) (PEDOT)/COOH-PEDOT polymeric outermost layer, ...
