On semi-porous items, MMD II offers better results as compared to cyanoacrylate fuming and luminescent staining (Jones, 2002). Porous materials contain small openings or holes in their composition. Some materials can be classified as semi-porous. A McIIwain tissue chopper (Gabler, Bad Schwabach, Germany) was used to prepare 400 μm thick transverse slices which were transferred to semi porous cell culture inserts (Millipore, Bedford, MA, USA; 0.4 mm). These materials typically have low density. It did not receive much interest, however until 1990 when Leigh Canham demonstrated luminescence from porous Si [20], which led to much excitement around the possibility of all Si photonic devices. 0 0. 3.
