Understanding the changes in milk at a nanostructural level during high-pressure (HP) treatment can provide new insights to improve safety and functionality of dairy products. In this study, modifications nanostructure HP were studied situ by small-angle X-ray scattering (SAXS). Skimmed was pressurized 200 or 400 MPa 25, 40 60 °C held for 5 10 min, effect single- double-HP also investigated. mo...

This study aimed to understand the structural devolution of 10% w/w rennet-induced (RG) and transglutaminase-induced acid (TG) gels in H2O D2O under vitro gastric conditions with without pepsin. The real-time structure at a nano- (e.g. colloidal calcium phosphate (CCP) micelle) micro- (gel network) level was determined using ultra-small (USANS) small-angle neutron scattering (SANS) electron mic...

In order to increase the therapeutic effect of doxorubicin (DOX) on bone metastases, a multifunctional micelle was developed by combining pH-sensitive characteristics with bone active targeting capacity. The DOX loaded micelle was self-assembled by using doxorubicin-poly (ethylene glycol)-alendronate (DOX-hyd-PEG-ALN) as an amphiphilic material. The size and drug loading of DOX loaded DOX-hyd-P...

Traditional micelle self-assembly is driven by the association of hydrophobic segments of amphiphilic molecules forming distinctive core-shell nanostructures in water. Here we report a surprising chaotropic-anion-induced micellization of cationic ammonium-containing block copolymers. The resulting micelle nanoparticle consists of a large number of ion pairs (≈60,000) in each hydrophobic core. U...

More than 80% of the total milk protein contains caseins that are to forms α-s1, α-s2, β-casein and kappa casein. Kappa casein is smaller than other milk proteins but due to have a role in size and stability of micelles. The present study describes polymorphism of kappa casein gene. This is the first study of kappa casein gene polymorphism in Najdi cattle of Iran. We used the polymerase chain r...

BACKGROUND Polymeric micelles attract great attention in drug delivery and therapeutics. Various types of block copolymers have been designed for the application in biomedical fields. If we can introduce additional functional groups to the block copolymers, we can achieve advanced applications. In this regards, we tried to introduce aggregation induced emission enhancement (AIE) unit in the blo...

The local environment within a recently developed anthracene-shelled micelle (ASM), which is a micelle-like nanocapsule composed of anthracene-embedded amphiphiles, was investigated by steady-state and time-resolved spectroscopy of an encapsulated solvatochromic fluorescent probe molecule, coumarin 153 (C153). The absorption maximum of encapsulated C153 (452 nm) is more red-shifted than that of...

Micelle formation in surfactant solutions is a self-assembly process governed by complex interplay of solvent-mediated interactions between hydrophilic and hydrophobic groups, which are commonly called heads and tails. However, the head-tail repulsion is not the only factor affecting the micelle formation. For the first time, we present a systematic study of the effect of chain rigidity on crit...

A dodecylphosphocholine micelle of 86 monomers with 5776 water molecules has been simulated under NPT conditions for 3.2 ns using GROMACS2.0. The micelle was found to be very dynamic. Some of the C-C bonds, independent of their position in the DPC monomer, adopt gauche conformation and the trans <--> gauche transitions are quite frequent. An average of about 11% of the C-C bonds in the micelle ...
