Over the past decade we have developed methods for modifying nanoparticles with oligonucleotides and explored how they can be used as designer constructs for preparing highly ordered, highly functional materials. The unusual properties of these materials make them particularly useful in biodiagnostics and intracellular gene regulation. This seminar will focus on the rules that govern the use of these conjugates, on sequence specific crystallization and protein detection, and on "antisense" therapy. Specifically we will introduce the concept of the "antisense particle" and similarly functionalized siRNA particles having unique properties that make them very well-suited for gene regulation. The particles are highly resistant to nuclease digestion, have tailorable binding constants for target mRNA, and exhibit high entry efficiency into multiple cell types. By tailoring the chemistry on the nanoparticle surface and controlling the particles' binding strength to complementary target sequences, we can control the degree of protein expression.
