We successfully arrayed microtubules in nanotracks with defined polarities, and visualized the dual transport of Qdot525 and Qdot655, carried by kinesin and dynein, respectively. Focusing on an individual MT manipulation by a nanotrack, we improved orientation efficiency by up to 90%, in comparison to 70% that is accomplished using conventional methods. This was realized by integrating nanofabrications...
A vertical microcavity laser structure with an active layer of Stranski-Krastanow quantum dots was fabricated for the first time. The microcavity consists of an InGaAs quantum dot layer grown by MOCVD, located between two AlAs/Al 0.2 Ga 0.8 As distributed Bragg-reflector mirrors. The length of the microcavity was 4λ(λ = 884 nm). The cavity effect was evidenced...
