Descripción general

Pluronic® F108 is a tri block copolymer and a terminal primary dihydroxy-functional oligomer. It behaves as a nonionic surfactant. It is a surface active material whose properties are dependent on the hydrophilic (EO)/hydrophobic (PO) ratio. High EO content gives better o/w stabilizers.

Aplicación

Hard and soft surface cleaners, defoamers in coatings and water treatment. Lubricant in metal working, anti-foaming aid and extender for linear and cross-linked polyesters and polyurethanes.
Pluronic® F108 was used as a surfactant in a medium to prevent the cells from sticking to the surface of a microfluidic device.{7}-{11}Pluronic may be potentially useful as a pathogen detector. It was used in the analysis of microbial community and genotyping single nucleotide polymorphisms (SNPs).{9} The triblock copolymer was used as a pore template for the fabrication of porous carbons and carbon/silica composite.{10}

The emergence and spread of antibiotic-resistant bacteria are aggravated by incorrect prescription and use of antibiotics. A core problem is that there is no sufficiently fast diagnostic test to guide correct antibiotic prescription at the point of care. Here, we

Understanding how forces orchestrate tissue formation requires technologies to map internal tissue stress at cellular length scales. Here, we develop ultrasoft mechanosensors that visibly deform under less than 10 Pascals of cell-generated stress. By incorporating these mechanosensors into multicellular spheroids
