Morse AJ, Armes SP, Thompson KL, Dupin D, Fielding LA, Mills P, Swart R. Novel Pickering emulsifiers based on pH-responsive poly(2-(diethylamino)ethyl methacrylate) latexes. Langmuir. 2013 May 7;29(18):5466-75. doi: 10.1021/la400786a.

Abstract. The emulsion copolymerization of 2-(diethylamino)ethyl methacrylate (DEA) with a divinylbenzene cross-linker in the presence of monomethoxy-capped poly(ethylene glycol) methacrylate (PEGMA) at 70 °C afforded near-monodisperse, sterically stabilized PEGMA-PDEA latexes at 10% solids. Dynamic light scattering studies indicated intensity-average diameters of 190 to 240 nm for these latexes at pH 9. A latex-to-microgel transition occurred on lowering the solution pH to below the latex pKa of 6.9....

Brunton ER, Whelan IP, French R, Burgess MN, Burgess IF. Head louse egg and nit remover-a modern "Quest for the Holy Grail". PeerJ. 2019 Apr 15;7:e6759. doi: 10.7717/peerj.6759. 

Abstract. The eggs of head lice are fixed to the hair of their hosts by means of a persistent glue-like fixative that is not chemically bound to the substrate. Eggshells stuck to hairs after successfully treating the infestation are a cosmetic issue and a source of misunderstanding about whether the infestation is eliminated. Hitherto, no effective treatment to loosen louse eggs and nits has been found.

Williams M, Warren NJ, Fielding LA, Armes SP, Verstraete P, Smets J. Preparation of double emulsions using hybrid polymer/silica particles: new pickering emulsifiers with adjustable surface wettability. ACS Appl Mater Interfaces. 2014 Dec 10;6(23):20919-27. doi: 10.1021/am505581r. 

Abstract. A facile route for the preparation of water-in-oil-in-water (w/o/w) double emulsions is described for three model oils, namely, n-dodecane, isopropyl myristate, and isononyl isononanoate, using fumed silica particles coated with poly(ethylene imine) (PEI). The surface wettability of such hybrid PEI/silica particles can be systematically adjusted by (i) increasing the adsorbed amount of PEI and (ii) addition of 1-undecanal to the oil phase prior to homogenization.

Naoui W, Bolzinger MA, Fenet B, Pelletier J, Valour JP, Kalfat R, Chevalier Y. Microemulsion microstructure influences the skin delivery of an hydrophilic drug. Pharm Res. 2011 Jul;28(7):1683-95. doi: 10.1007/s11095-011-0404-y.

Abstract.  We aimed to investigate the influence of microemulsion nanoscale organization as either oil-in-water droplets, water-in-oil droplets, or bicontinuous structures on skin delivery of drugs assisted by microemulsions.
