“…In one work from Yang et al (2015), MIP microsphere (MIPMS) were fabricated to extract bisphenols (BPs), which have certain toxicity to human body, from human urine samples (Yang et al, 2015). Adsorption experiments verified a more effective result of as-prepared MIPMS than non-imprinted polymer microsphere (NIPMS) for selective extraction of eight kinds of BP from samples.…”

Pickering emulsion, a kind of emulsion stabilized only by solid particles locating at oil–water interface, has been discovered a century ago, while being extensively studied in recent decades. Substituting solid particles for traditional surfactants, Pickering emulsions are more stable against coalescence and can obtain many useful properties. Besides, they are more biocompatible when solid particles employed are relatively safe in vivo. Pickering emulsions can be applied in a wide range of fields, such as biomedicine, food, fine chemical synthesis, cosmetics, and so on, by properly tuning types and properties of solid emulsifiers. In this article, we give an overview of Pickering emulsions, focusing on some kinds of solid particles commonly serving as emulsifiers, three main types of products from Pickering emulsions, morphology of solid particles and as-prepared materials, as well as applications in different fields.

“…1−4 Pickering emulsions are more stable than classic surfactant stabilized emulsions due to the significant reduction in interfacial energy by each solid particle that irreversibly binds to the interface. Pickering emulsions have found widespread uses, including solid phase extraction, 5,6 drug encapsulation, 7 and enhanced oil recovery. 8,9 Depending on the uniformity of their size, the colloidal particles confined to the interface can densely pack into 2D crystalline arrays as the emulsions coarsen, reducing the interfacial energy.…”

Nanoparticle-surfactants (NPSs) assembled at water−oil interfaces can significantly lower the interfacial tension and can be used to stabilize liquids. Knowing the formation and assembly and actively tuning the packing of these NPSs is of significant fundamental interest for the interfacial behavior of nanoparticles and of interest for water purification, drug encapsulation, enhanced oil recovery, and innovative energy transduction applications. Here, we demonstrate by means of interfacial tension measurements the high ionic strength helps the adsorption of NPSs to the water−oil interface leading to a denser packing of NPSs at the interface. With the reduction of interfacial area, the phase transitions from a "gas"like to "liquid" to "solid" states of NPSs in two dimensions are observed. Finally, we provide the first in situ real-space imaging of NPSs at the water−oil interface by atomic force microcopy.

“…In most cases the template is the target molecule that is to be selectively retained by the MIPs, and most of the PEEs-MIPs were synthesized using the same molecule as target and template. For example, Yang et al (2015) prepared MIPs for selective SPE of eight bisphenols from human urine samples using BPA as template. For difficult-to-achieve template or considering the risks of template leakage during applications, a structural analog can be used as dummy template for the synthesis.…”

Phenolic environmental estrogen (PEE) is one of the most common endocrine disrupting chemicals whose interference with the normal function of the endocrine system in animals and humans raised concern to their potential impact on wildlife and humans health. Research on PEEs calls for a high selectivity analytical methods. Molecularly imprinted polymers (MIPs) are synthetic polymers having a predetermined selectivity for a given analyte, or group of structurally related compounds, which make them ideal materials to be used in analysis of PEEs. During the past few years, a huge amount of papers have been published dealing with the use of MIPs in the analysis of PEEs. In this review, we focus on the recent applications of MIPs to analyze PEEs. We describe the preparation of MIPs and discuss different methods of polymerization. We highlight the latest applications of MIPs in the analysis of PEEs, including nanomaterial MIPs as sorbent for solidphase extraction and MIPs as electrochemical sensors. This review provides a good platform for the analysis and monitoring of PEEs in complicated matrixes and offers suggestions for future success in the field of MIPs.
