3-Dimensionally ordered macroporous PEDOT ion-exchange resins prepared by vapor phase polymerization for triggered drug delivery: Fabrication and characterization

Achieving Color and Function with Structure: Optical and Catalytic Support Properties of ZrO2 Inverse Opal Thin Films

“…In the subsequent stage of the colloidal crystal templating strategy, the colloidal crystal (i.e., opal) is used as a sacrificial template to fabricate inverse opal replicas, comprising a face-centered cubic array of air spheres (macropores) in a solid matrix. 42−69 To obtain the inverse opal, the interstitial voids in the colloidal crystal template (26 vol % of the structure) are filled with a solid material via sol–gel, electrochemical, or nanoparticle infiltration methods, after which the original colloidal crystal template is selectively removed by dissolution or calcination (heating in air). A multitude of inverse opal-based photonic crystal materials have been synthesized by this strategy, including metals, metal oxides, conducting polymers, and carbon materials.…”

“…A multitude of inverse opal-based photonic crystal materials have been synthesized by this strategy, including metals, metal oxides, conducting polymers, and carbon materials. 29,42−69 The three-dimensionally ordered macroporous structure of inverse opals, together with their inherent photonic crystal properties, creates new opportunities in optical sensor development, separation, photocatalysis, and catalysis, among others. Particularly valuable in this context are inverse opal thin films suitable for “on chip” diagnostic or sensing applications, though reliable design strategies toward large-area inverse opal thin films are currently limited, prompting further research in this area.…”

Characterization of Zinc Oxide Nanoparticle Cross-Linked Collagen Hydrogels

“…The tubes were placed in a thermomixer (Eppendorf, Hamburg, Germany) maintained at 37 °C and 300 rpm. At predetermined timepoints, 0.5 mL of release medium was withdrawn and replaced with an equal volume of fresh PBS to maintain sink conditions and the drug content was analysed via HPLC [ 29 ].…”

Recent advances in the aqueous applications of PEDOT

“…[57][58][59][60] Despite this promise, there are a relatively small number of research articles published in recent years on this topic. Yasin et al 61 employed the templating approach to form inverse opal structures of PEDOT:Tos using polystyrene nanospheres as a sacricial support. The resultant 3D PEDOT material was used for loading and release of the model anionic drug dexamethasone phosphate (DexP À ), which is used to treat an inactive/underactive adrenal gland or certain immune disorders and skin problems, asthma or arthritis.…”
