Ultrasonic particle manipulation technique is a non-contact label-free method for manipulating micro- and nano-scale particles using ultrasound, which has obvious advantages over traditional optical, magnetic, electrical micro-manipulation techniques; it gained extensive attention in micro-nano recent years. This paper introduces the basic principles methods of ultrasonic techniques, provides d...
We have constructed an experimental system to measure a piconewton lateral force using dual cantilevers which cross with each other. The resolution of the lateral force is estimated to be 3.3 p ± 0.2 pN, which is comparable to forces due to thermal fluctuation. This experimental apparatus works so easily that it will enable us to determine forces during nano-manipulation and nano-tribological m...
In-addition to the applications of imaging and characterization, proximal probes are proposed to be used as three-dimensional (3-D) nano-scale manufacturing tools in this paper. Commercially available Atomic Force Microscope (AFM) systems are mainly limited to 1-D or 2-D manipulation tasks, and advanced 3-D nano-manufacturing applications are not possible. Therefore, this paper proposes 3-D nan...
In this paper, dynamic behavior of nanoparticle motion during nanoprobe-based manipulation is investigated. Pushing, pulling or picking manipulation of the particles results in different behavior of rolling, sliding, sticking, or rotation. For a given point of contact of the nanoprobe tip on the particle, nanoprobe load magnitude and direction and critical frictional forces are obtained in all ...
The newly formed North West Laser Engineering Consortium (NWLEC), a strategic alliance between the Universities of Liverpool and Manchester in the North West of England UK, has an ongoing research programme into micro and nano manipulation techniques for microassembly and manufacture. A key area of research is optical trapping. Since their invention just over 20 years ago, optical traps have em...
A nanolaboratory—a prototype nanomanufacturing system—is presented, which is composed with a nanorobotic manipulation system with 4 units and 16 degrees-offreedom (DOFs), a nano fabrication system based on electron-beam-induced deposition (EBID) with an internal or external precursor evaporation reservoir equipped with a thermal field emission electron source or a nanotube cold cathode, and a r...
Yeast nanobiotechnology is a recent field where nanotechniques are used to manipulate and analyse yeast cells and cell constituents at the nanoscale. The aim of this review is to give an overview and discuss nanobiotechnological analysis and manipulation techniques that have been particularly applied to yeast cells. These techniques have mostly been applied to the model yeasts Saccharomyces cer...
