Abstract
Conventional medicine is reactive to tissue-level problems that are discovered at the symptomatic level. Nanomedicine has the promise to diagnose and treat problems at the molecular level inside single-cells, far earlier and prior to the appearance of traditional symptoms. Beyond the obvious application of bionanotechnology to medicine, the approach is fundamentally different.
Nanomedicine, as a nanotechnology approach, is a "bottoms up" rather than "top down" approach to medicine - treating cells one cell at a time. Nanomedicine is a form of regenerative medicine, not just a killing of diseased cells whereby tissues and organs that are repairable can be "regenerated" through repair mechanisms. It typically combines use of molecular biosensors to provide for feedback control of treatment and repair on a single-cell basis. Feedback control is a common feature of engineered systems, but relatively foreign to medicine.
This tutorial will cover general problems and approaches to the design of engineered nanomedical systems. An example to be covered is the engineering design of programmable multilayered nanoparticles (PMNP) to control a multi-sequence process of targeting to rare cells in-vivo, re-targeting to intracellular sites, and controlling of final gene/drug delivery. Therapeutic genes can be manufactured inside living cells as a "nanofactory" under the control of these molecular biosensors providing feedback- controlled single cell medicine.
