OPTIMISED HYPERBOLIC MICROCHANNELS FOR THE MECHANICAL CHARACTERISATION OF BIO-PARTICLES

Redazione
(AGENPARL) – LONDON (UNITED KINGDOM), mar 15 settembre 2020 The transport of bio-particles in viscous flows exhibits a rich variety of dynamical behaviour, such as morphological transitions, complex orientation dynamics or deformations. Characterising such complex behaviour under well controlled flows is key to understanding the microscopic mechanical properties of biological......

IN VITRO BIOACCESSIBILITY OF FISH OIL-LOADED HOLLOW SOLID LIPID MICRO- AND NANOPARTICLES

Redazione
(AGENPARL) – LONDON (UNITED KINGDOM), mer 09 settembre 2020 Fish oil-loaded hollow solid lipid micro- and nanoparticles were prepared by atomization of the CO2-expanded lipid mixture. The obtained particles were spherical and free-flowing with an average particle size of 6.9 µm. Fish oil loading efficiency was achieved at 92.3% (w/w).......

MORPHOLOGY CONTROL OF SILICONE/POLY(METHYL METHACRYLATE) (ELASTIC/GLASSY) COMPOSITE PARTICLES

Redazione
(AGENPARL) – LONDON (UNITED KINGDOM), mer 09 settembre 2020 Composite particles consisting of elastic silicone and glassy poly(methyl methacrylate) (PMMA) were prepared. Seeded polymerization of methyl methacrylate (MMA) was carried out in the presence of silicone elastic particles, which were prepared via a radical-mediated thiol-ene click reaction between thiol-terminated silicone......

SURFACE PRESSURE OF LIQUID INTERFACES LADEN WITH MICRON-SIZED PARTICLES

Redazione
(AGENPARL) – LONDON (UNITED KINGDOM), mar 08 settembre 2020 We consider the surface pressure of a colloid-laden liquid interface. As micron-sized particles of suitable wettability can be irreversibly bound to the liquid interface on experimental timescales, we use the canonical ensemble to derive an expression for the surface pressure of......

FABRICATION OF 3D CONCENTRIC AMPHIPHILIC MICROPARTICLES TO FORM UNIFORM NANOLITER REACTION VOLUMES FOR AMPLIFIED AFFINITY ASSAYS

Redazione
(AGENPARL) – LONDON (UNITED KINGDOM), mar 08 settembre 2020 Reactions performed in uniform microscale volumes have enabled numerous applications in the analysis of rare entities (e.g. cells and molecules). Here, highly monodisperse aqueous droplets are formed by simply mixing microscale multi-material particles, consisting of concentric hydrophobic outer and hydrophilic inner......

MICRO- AND NANOPLASTICS – CURRENT STATE OF KNOWLEDGE WITH THE FOCUS ON ORAL UPTAKE AND TOXICITY

Redazione
(AGENPARL) – LONDON (UNITED KINGDOM), mer 02 settembre 2020 The production and use of plastics has constantly increased over the last 30 years. Over one third of the plastics is used in disposables, which are discarded within three years of their production. Despite efforts towards recycling, a substantial volume of......
