Au Octahedral Nanosponges: 3D Plasmonic Nanolenses for Near-Field Focusing.

Journal of the American Chemical Society, 2023
Here, we report the synthesis of three-dimensional plasmonic nanolenses for strong near-field focusing. The nanolens exhibits a distinctive structural arrangement composed of nanoporous sponge-like networks within their interior.

Glycan-Modified Cellular Nanosponges for Enhanced Treatment of Cholera Toxin-Induced Secretory Diarrhea.

Journal of the American Chemical Society
Cholera is a severe infectious disease caused by the Gram-negative bacterium Vibrio cholerae after colonization in the intestinal tract. Cholera toxin (CT), a key exotoxin protein, primarily causes acute secretory diarrhea and life-threatening ...

Metal Oxide “Nanosponges” as Chemical Sensors: Highly Sensitive Detection of Hydrogen with Nanosponge Titania

Angewandte Chemie International Edition, 2007
Semiconducting metal oxides are widely considered as the most promising platform for solid-state gas sensors. Due to enhanced responsiveness of conductance to surface effects in low dimensional nanostructures, various forms of nanostructured metal oxides have been synthesized and their sensing properties studied.

Nanosponges for hydrogen storage

Journal of Materials Chemistry, 2012
Hydrogen storage by physisorption is a very promising technique due to its fast kinetics and full reversibility. The key to reach high storage capacities is high specific surface area. Extremely large surface areas can only be achieved by materials with high porosity, i.e., nanosponges like MOF-177 (4239 m2 g−1) and DUT-23(Co) (4850 m2 g−1).

Cyclodextrin-based nanosponges: A critical review

Carbohydrate Polymers, 2017
Cyclodextrin-based nanosponges (CD-NS) are innovative cross-linked cyclodextrin polymers nanostructured within three-dimensional network. CD-NS are highly porous nanoparticles characterized by crystalline or amorphous structure, spherical shape and swelling properties. Different cross-linkers provide variety of nanosponges.

Nanosponge formulations as oxygen delivery systems

International Journal of Pharmaceutics, 2010
Three types of cyclodextrin nanosponges were synthetized cross-linking α, β or γ cyclodextrin with carbonyldiimidazole as cross-linker. Nanosponges are solid nanoparticles previously used as drug carriers. In this studies cyclodextrin nanosponges were developed as oxygen delivery system.
