Abstract
A detailed study of the different structural transitions of the triblock copolymer PEO27-PPO61-PEO27 (P104) in water, in the dilute and semi-dilute regions, is addressed here as a function of temperature and P104 concentration (CP104) by mean of complimentary methods: viscosimetry, densimetry, dynamic light scattering, turbidimetry, polarized microscopy, and rheometry. The hydration profile was calculated through density and sound velocity measurements. It was possible to identify the regions where monomers exist, spherical micelle formation, elongated cylindrical micelles formation, clouding points, and liquid crystalline behavior. We report a partial phase diagram including information for P104 concentrations from 1 × 10-4 to 90 wt.% and temperatures from 20 to 75 °C that will be helpful for further interaction studies with hydrophobic molecules or active principles for drug delivery.

Abstract
Pluronics are a class of amphiphilic tri-block copolymers with wide pharmaceutical applicability. In the past decades, the ability to form biocompatible nanosized micelles was exploited to formulate stable drug nanovehicles with potential use in antitumor therapy. Due to the great potential for tuning physical and structural properties of Pluronic unimers, a panoply of drug or polynucleotide-loaded micelles was prepared and tested for their antitumoral activity. The attractive inherent antitumor properties of Pluronic polymers in combination with cell targeting and stimuli-responsive ligands greatly improved antitumoral therapeutic effects of tested drugs. In spite of that, the extraordinary complexity of biological challenges in the delivery of micellar drug payload makes their therapeutic potential still not exploited to the fullest. In this review paper we attempt to present the latest developments in the field of Pluronic based nanovehicles and their application in anticancer therapy with an overview of the chemistry involved in the preparation of these nanovehicles.

Abstract
Aqueous solutions of polyethylene oxide-polypropylene oxide-polyethylene oxide (PEO-PPO-PEO) copolymers form micelles and cubic lattices as their temperature is raised. The presence of added solutes within the dispersions can also affect the kinetics of structure formation. Here, we investigate the structures formed in the amphiphiles P104, P105, and F108 solutions at 31% mass per v both neat and co-formulated with the drug cisplatin (0.02% to 0.1% mass per v) using small-angle X-ray scattering. P104 formed BCC colloidal crystals while P105 and F108 formed FCC structures. Cisplatin had a minor influence of the formation and stability of the crystals during these thermal excursions. The largest interaction between the amphiphiles and cisplatin was P104 where there was a 2% reduction in the BCC lattice parameter of P104 as cisplatin loading rose to 0.1% at 28 °C. The F108 unit cell swelled ∼2% upon cisplatin loading of 0.1%. A progressive evolution and breakdown of these structures was noted as the temperature rose from 10 °C to 35 °C. For the different amphiphiles, crystal thermal expansion coefficients of ∼1 × 10-2 °C-1 were determined in neat and loaded amphiphiles with cisplatin and all the crystals swelled with increasing temperature.
