In conclusion, ET is a polyfunctional cytokine that affects monocytes as well as vascular smooth muscle cells, anterior pituitary cells, and renal mesangial cells. In the biologic interface between ischemic or injured endothelium and monocytes, neutrophils, or lymphocytes, ET may play a significant role.

The electronic theory is based on the assumption that the mucoadhesive hydrogel and the target biological tissue have different electronic structures. When two materials come into contact with each other, electron transfer occurs, causing the formation of a double layer of electrical charge at the bioadhesive-biological interface. The bioadhesive force is believed to be due to attractive forces across this electrical double layer.

The three fundamental lyotropic liquid crystal structures are depicted in Figure 1. The lamellar structure with bimolecular lipid layers separated by water layers (Figure 1, center) is a relevant model for many biological interfaces. Despite the disorder in the polar region and in the hydrocarbon chain layers, which spectroscopy reveals are close to the liquid states, there is a perfect repetition in the direction perpendicular to the layers. Because of this one-dimensional periodicity, the thicknesses of the lipid and water layers and the cross-section area per lipid molecule can be derived directly from x-ray diffraction data. 

One type of lipid that is dominant in biological interfaces is lecithin, and lecithin-water systems have therefore been examined extensively by different physical techniques. Small s binary system (3) for egg lecithin-water is presented in Figure 2. The lamellar phase is formed over a large composition range, and, at very low water content, the phase behavior is quite complex. Their structures as proposed by Luzzati and co-workers (4) are either lamellar with different hydrocarbon chain packings or based on rods both types are discussed below.

The examples described above reveal the versatility and potential of bottom-up approaches for generating structures with controlled substructures and, moreover, positioned functionalities to modulate the material-biology interfaces. Certainly,... 

Another part of the effort to use chemistry to understand and influence biology is seen in the field of medicinal chemistry. Here too there is intellectual flow in both directions across the chemistry-biology interface, as chemists take what is known about the biology of disease and invent cures using chemicals, usually synthetic chemicals. Success in this field for chemists involves both listening to biology and speaking with chemistry.
