“…There are many competing micromanipulation techniques being actively researched, including mechanical manipulation using AFM tips [1], optical tweezers [2], dielectrophoresis [3], magnetic traps [4] and acoustic traps [5]. Each technique has distinct advantages and disadvantages, in terms of the degree of force that can be applied or the precision of the particle manipulation.…”

A novel, miniaturized optoelectronic tweezers (OET) system has been developed using a CMOS-controlled GaN micro-pixelated light emitting diode (LED) array as an integrated micro-light source. The micro-LED array offers spatio-temporal and intensity control of the emission pattern, enabling the creation of reconfigurable virtual electrodes to achieve OET. In order to analyse the mechanism responsible for particle manipulation in this OET system, the average particle velocity, electrical field and forces applied to the particles were characterized and simulated. The capability of this miniaturized OET system for manipulating and trapping multiple particles including polystyrene beads and live cells has been successfully demonstrated.

“…One of the most important experimental tools in this regard is the atomic force microscope (AFM), where the AFM tip is employed for pushing nanoparticles. For example, numerous papers have been published that focus on how the AFM is best and most efficiently used as a nanoparticle manipulation tool [2][3][4][5][6][7][8], while other work investigates the underlying physical mechanisms governing nanoparticle manipulation [9][10][11][12][13][14][15]. Over the last few years, however, a growing number of experimental and theoretical studies have looked into how nanoparticle manipulation can be used as a tool for nanotribology [16][17][18][19][20][21][22].…”

Quantifying Pathways and Friction of Nanoparticles During Controlled Manipulation by Contact-Mode Atomic Force Microscopy

Measuring interfacial friction during the manipulation of nanoparticles is becoming an increasingly important approach in nanotribology research. In this work, antimony and gold particles deposited on flat graphite surfaces have been translated by the tip of an atomic force microscope in contact mode along defined pathways. Two different manipulation techniques are discussed with respect to pathway control and friction quantification. The first technique includes pushing the particles from the side, which often results in a loss of the particle during translation due to unwanted sidewards motion. We analyze this phenomenon with an analytical model and find good agreement with experiments. An alternative approach is to move the particle while the tip remains on its top. We demonstrate that this approach allows better manipulation pathway control and that simultaneous interfacial friction measurements are in quantitative agreement with the first manipulation method.

“…Beach et al [9] have used the AFM to directly measure the force of adhesion between drug particles with regular geometries and polymeric surfaces. Fattah [10] has employed the Xie [11] equations to investigate the effect of asperities with very small radii, from 0 to 10 nm, on the adhesion force of spherical particles. Based on the modeling performed by Zhou [12], in the contact between rough surfaces, only portions of the apparent areas, which contain a set of contact points, come into contact and are designated as the real contact area.…”

Since surface roughness greatly influences the force of adhesion between two bodies, the dynamic behavior of different biological micro/nanoparticles on rough surfaces during 3D manipulation operations has been studied in this paper by employing the atomic force microscope (AFM). In this regard, the force of adhesion between two surfaces has been simultaneously investigated on the basis of two important approaches. First, the interactions between two surfaces have been evaluated based on the available contact mechanics theories, and depending on the type of biological nanoparticle studied in this research, an appropriate model has been presented. Then, the common adhesion models of Rumpf and Rabinovich have been modified based on the Van der Waals force and with regard to the cylindrical geometry of the nanoparticles. Finally, based on the Schwartz method, by developing the adhesion model based on the two approaches mentioned above, the adhesion force between cylindrical biological nanoparticles and rough surfaces has been extracted for the first time. The dynamic behavior of nanoparticles in 3D manipulation on a rough substrate has been modeled and then simulated and analyzed. The simulation results indicate that, by increasing the asperity radius, the critical force needed to manipulate a nanoparticle increases. Also, in contrast to the sliding mode, the critical force of movement in the rolling mode diminishes with the increase of nanoparticle radius. The experimental results obtained from the topography of glass and silica substrates indicate that the Rumpf model underestimates the adhesion force relative to the Rabinovich model.
