Engineering cells with active-ingredient-loaded micro/nanoparticles is becoming increasingly popular for imaging and therapeutic applications. A critical yet inadequately addressed issue during its implementation concerns the significant number of particles that remain unbound following the engineering process, which inadvertently generate signals and impart transformative effects onto neighbor...

Understanding adhesion of micro-particles particularly microcapsules containing a functional active on fabric surface is crucial to effective delivery of the active to the latter. Fabric surface is very rough, and direct measurement of the adhesion of single micro-particles on surfaces with roughnesses greater than the particle diameter can be difficult. In this work cotton films were successfu...

A set of laboratory experiments has been carried out to determine if micro-needles (MNs) can enhance penetration depths of high-speed micro-particles delivered by a type of gene gun. The micro-particles were fired into a model target material, agarose gel, which was prepared to mimic the viscoelastic properties of porcine skin. The agarose gel was chosen as a model target as it can be prepared ...

We aimed to develop a micro-robot that can crawl on contact surfaces in biological environments. The prototype chassis of this micro-bot consists of a lipid membrane that encapsulates and bonds micro-sized magnetic particles. By applying a rotating magnetic field, we hope to obtain a micro-crawler robot. In this report, we describe our observations of the rotational movement of liposomes (10–60...

We investigate holographic optical tweezers manipulating micro-beads at a suspended air-liquid interface. Axial confinement of the particles in the two-dimensional interface is maintained by the interplay between surface tension and gravity. Therefore, optical trapping of the micro-beads is possible even with a long distance air objective. Efficient micro-circulation of the liquid can be induce...

Cs 2 HfF 6 (CHF) nano- and HfCl (CHC) micro-particles were synthesised using wet chemical methods. The luminescence of CHC single crystals is replicated in the micro-particles, paving way toward particle-based phosphor materials.

One approach for a particle radiobiological experiments is to use solid-state nuclear track detectors (SSNTDs) as support substrates to record the a particle hit positions on the targets. To facilitate accurate characterization of the hit positions as well as the incident a particle energies, micro-collimators are required in these experiments to restrict the incidentaparticles to thosewith sma...
