The established ‘Hydrophilic Solubilisation Technology’ (HST) was used for embedding the lipophilic drug with lecithin and gelatin, yielding core-shell microparticles of 1 µm size. The particle size of the drug, the formulation, and the thickness of the coating were investigated by using dynamic light scattering (DLS), microscopy, UV–Visible spectroscopy and small angle neutron scattering (SANS). The drug in the formulation was not in the oligomer form but in a competent uptake form, as shown by the UV–Visible spectroscopy. The DLS and microscopy depicted the product to consist of spheres (∼1 µm). The SANS experiment using deuterium contrast matching of the drug cores revealed a thin layer span of 5.6 nm, which is similar, but slightly larger as compared to the biological lipid membranes. The finding offers opportunities for further improvements of the formulation, e.g., by surface modification.A soluble core-shell formulation ‘AmbiShell’ of the hydrophobic antifungal polyene drug Amphotericin B was generated from drug, lecithin, and gelatin. The span of the lipid–gelatin shell was estimated by neutron scattering SANS with deuterium contrast matching of the drug core. 000183567 536__ $$0G:(DE-HGF)POF2-54G24$$a54G - JCNS (POF2-54G24)$$cPOF2-54G24$$fPOF II$$x0 000183567 588__ $$aDataset connected to CrossRef, juser.fz-juelich.de 000183567 65027 $$0V:(DE-MLZ)SciArea-210$$2V:(DE-HGF)$$aSoft Condensed Matter$$x1 000183567 65027 $$0V:(DE-MLZ)SciArea-190$$2V:(DE-HGF)$$aMedicine$$x0 000183567 65017 $$0V:(DE-MLZ)GC-130-2016$$2V:(DE-HGF)$$aHealth and Life$$x2 000183567 65017 $$0V:(DE-MLZ)GC-130-1$$2V:(DE-HGF)$$aHealth and Life$$x1 000183567 65017 $$0V:(DE-MLZ)GC-130$$2V:(DE-HGF)$$aLife Science and Health$$x0 000183567 693__ $$0EXP:(DE-MLZ)KWS2-20140101$$1EXP:(DE-MLZ)FRMII-20140101$$5EXP:(DE-MLZ)KWS2-20140101$$6EXP:(DE-MLZ)NL3ao-20140101$$aForschungs-Neutronenquelle Heinz Maier-Leibnitz$$eKWS-2: Small angle scattering diffractometer$$fNL3ao$$x0 000183567 7001_ $$0P:(DE-HGF)0$$aNawroth, Thomas$$b1 000183567 7001_ $$0P:(DE-HGF)0$$aKhoshakhlagh, Pooneh$$b2 000183567 7001_ $$0P:(DE-HGF)0$$aLangguth, Peter$$b3 000183567 7001_ $$0P:(DE-HGF)0$$aSchmueser, Lars$$b4 000183567 7001_ $$0P:(DE-HGF)0$$aHellmann, Nadja$$b5 000183567 7001_ $$0P:(DE-HGF)0$$aDecker, Heinz$$b6 000183567 7001_ $$0P:(DE-Juel1)145431$$aSzekely, Noemi$$b7 000183567 773__ $$0PERI:(DE-600)2012720-0$$a10.1002/ejlt.201400069$$gVol. 116, no. 9, p. 1167 - 1173$$n9$$p1167 - 1173$$tEuropean journal of lipid science and technology$$v116$$x1438-7697$$y2014 000183567 909CO $$ooai:juser.fz-juelich.de:183567$$pVDB$$pVDB:MLZ 000183567 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR 000183567 915__ $$0StatID:(DE-HGF)0110$$2StatID$$aWoS$$bScience Citation Index 000183567 915__ $$0StatID:(DE-HGF)0111$$2StatID$$aWoS$$bScience Citation Index Expanded 000183567 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection 000183567 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bThomson Reuters Master Journal List 000183567 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS 000183567 915__ $$0StatID:(DE-HGF)0300$$2StatID$$aDBCoverage$$bMedline 000183567 915__ $$0StatID:(DE-HGF)0310$$2StatID$$aDBCoverage$$bNCBI Molecular Biology Database 000183567 915__ $$0StatID:(DE-HGF)1050$$2StatID$$aDBCoverage$$bBIOSIS Previews 000183567 915__ $$0StatID:(DE-HGF)1060$$2StatID$$aDBCoverage$$bCurrent Contents - Agriculture, Biology and Environmental Sciences 000183567 9141_ $$y2014 000183567 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)145431$$aForschungszentrum Jülich GmbH$$b7$$kFZJ 000183567 9132_ $$0G:(DE-HGF)POF3-600$$1G:(DE-HGF)POF3$$2G:(DE-HGF)POF$$9G:(DE-HGF)POF3-6G15$$aDE-HGF$$bProgrammorientierte Förderung$$lPOF III$$vForschungsbereich Materie$$x0 000183567 9132_ $$0G:(DE-HGF)POF3-623$$1G:(DE-HGF)POF3-620$$2G:(DE-HGF)POF3-600$$9G:(DE-HGF)POF3-6G4$$aDE-HGF$$bForschungsbereich Materie$$lVon Materie zu Materialien und Leben$$vFacility topic: Neutrons for Research on Condensed Matter$$x1 000183567 9131_ $$0G:(DE-HGF)POF2-54G24$$1G:(DE-HGF)POF2-540$$2G:(DE-HGF)POF2-500$$3G:(DE-HGF)POF2$$4G:(DE-HGF)POF$$aDE-HGF$$bStruktur der Materie$$lForschung mit Photonen, Neutronen, Ionen$$vJCNS$$x0 000183567 920__ $$lyes 000183567 9201_ $$0I:(DE-Juel1)JCNS-FRM-II-20110218$$kJCNS (München) ; Jülich Centre for Neutron Science JCNS (München) ; JCNS-FRM-II$$lJCNS-FRM-II$$x0 000183567 9201_ $$0I:(DE-Juel1)JCNS-1-20110106$$kNeutronenstreuung ; JCNS-1$$lNeutronenstreuung$$x1 000183567 9201_ $$0I:(DE-Juel1)ICS-1-20110106$$kICS-1$$lNeutronenstreuung$$x2 000183567 980__ $$ajournal 000183567 980__ $$aVDB 000183567 980__ $$aI:(DE-Juel1)JCNS-FRM-II-20110218 000183567 980__ $$aI:(DE-Juel1)JCNS-1-20110106 000183567 980__ $$aI:(DE-Juel1)ICS-1-20110106 000183567 980__ $$aUNRESTRICTED 000183567 981__ $$aI:(DE-Juel1)IBI-8-20200312 000183567 981__ $$aI:(DE-Juel1)JCNS-1-20110106 000183567 981__ $$aI:(DE-Juel1)ICS-1-20110106
