Abstract Critical Casimir forces emerge between objects, such as colloidal particles, whenever their surfaces spatially confine the fluctuations of order parameter a critical liquid used solvent. These act at short but microscopically large distances these reaching often hundreds nanometers. Keeping colloids is major experimental challenge, which can be addressed by means optical tweezers. Here...

In Western countries the incidence of the esophageal adenocarcinoma (EAC) has risen at a more rapid rate than that of any other malignancy. Despite intensive therapies this cancer is associated with extreme high morbidity and mortality. For this reason, novel effective therapeutic strategies are urgently required. Dendritic Cell (DC)-based immunotherapy is a promising novel treatment strategy, ...

The physical, chemical and optical properties of nano-scale colloids depend on their material composition, size and shape. There is a great interest in using nano-colloids for photo-thermal ablation, drug delivery and many other biomedical applications. Gold is particularly used because of its low toxicity. A property of metal nano-colloids is that they can have a strong surface plasmon resonan...

Nano-structured gas sensing materials, in particular nanoparticles, nanotubes, and nanowires, enable high sensitivity at a ppb level for gas sensors. For practical applications, it is highly desirable to be able to manufacture such gas sensors in batch and at low cost. We present here a strategy of in-situ wafer-level fabrication of the high-performance micro/nano gas sensing chips by naturally...

objective(s): binary hybrids of chitosan-zeolite have many interesting applications in separation and bacteriostatic activity. materials and methods: template free zsm-5 zeolite was synthesized by hydrothermal method, physical hydrogels of nano chitosan in the colloidal domain were obtained in the absence of toxic organic solvent and then nano chitosan/zsm-5 hybrid composites with nano chitosan...

Abstract Stabilization of nano-oxide suspensions is a very important process. Nowadays, synthetic polymers are used to increase stability the colloidal systems. However, this solution not ecological and incompatible with principles green chemistry. Instead polymers, their natural counterparts can be used. Herein, we present use bioactive polysaccharide—fucoidan as stabilizer nano-zinc(II) nano-...

Colloidal heat engines are paradigmatic models to understand the conversion of into work in a noisy environment - domain where biological and synthetic nano/micro machines function. While operation these across thermal baths is well-understood, how they function with noise statistics that non-Gaussian also lacks memory, simplest departure from equilibrium, remains unclear. Here we quantified pe...
