Sol–gel chemistry represents a powerful method for assembling
metal chalcogenide quantum dots into 3D connected architectures
without the presence of intervening ligands to moderate particle–
particle interactions. Wet gels prepared by the oxidative loss
of thiolate surface groups from chalcogenide nanoparticles can be9co]7o.Www$v2e6T)l
converted to xerogels (low porosity) or aerogels (high porosity), and
the quantum-confinement effects in these low-dimensional networks
decrease with increasing density of the network. In thisu G7pGR1B
Account, we describe the application of sol–gel chemistry to the
formation of CdSe architectures and discuss how surface modification
can lead to highly luminous monoliths, concluding with the9H]g#l!Z gJR/b

When lipid-directed assembly of silicic acid precursors is conducted'Q3H/E[.E\)v:K
in the presence of living cells, the cells intervene, surrounding
themselves with a fluid, multilayered lipid vesicle that interfaces
coherently with an ordered silica mesophase. This bio/nano
interface is unique in that its uniform nanostructure prevents:km2f%Z P{7Y4q:lj L
excessive drying of water, maintaining cell viability, yet provides
accessibility of the cell surface to small molecules. In comparison
to existing immobilization schemes, such as encapsulation within
sol–gel matrices, we show this interface to form by an active es.EK6Ir1a
interplay between the living cell and surrounding matrix, whichsq i+m)XK;o;m
we refer to as cell-directed assembly (CDA). Importantly and
perhaps uniquely, CDA creates a localized nanostructured microenvironmentsa9t%?C
