Two fluorescent materials have been localized in the adult firefly light organ by fluorescence microscopy. One of these is located in photocyte granules, has a maximum emission between 510 and 540 nm, is more fluorescent in basic than acidic solution, and is unstable in ultraviolet light, phosphomolybdic acid, and potassium permanganate. It is thought to be luciferin. The fluorescence of this material is very dim in untreated fireflies but increases substantially following sustained light emission induced by synephrine or prolonged electrical stimulation. It is suggested that the luciferin of untreated animals is bound in the granules and that binding suppresses its fluorescence. The second fluorescent material is located in the dorsal layer of the light organ, particularly in the cells bordering on the photogenic layer. This material has a maximum emission between 510 and 520 nm, is relatively stable in ultraviolet light, and rapidly disappears when light organs are exposed to water. Its identity and function are unknown.

The most advanced macromolecular materials are found in plants and animals, and certainly the connective tissues in mammals are amongst the most advanced macromolecular composites known to mankind. The efficient use of collagen, a fibrous protein, in the design of both soft and hard connective tissues is worthy of comment. Very crudely, in bone collagen serves as a highly efficient binder for the inorganic hydroxyappatite which stiffens the structure. The interactions between the organic fiber of collagen and the inorganic material seem to occur at the nano (scale) level of organization. Epitatic crystallization of the inorganic phase on the fibers has been reported to give a highly anisotropic, stress responsive, structure. Soft connective tissues also have sophisticated oriented hierarchical structures. The collagen fibers are “glued” together by a highly hydrated gel-like proteoglycan matrix. One of the simplest structures of this type is tendon which functions primarily in uniaxial tension as a reinforced elastomeric cable between muscle and bone.

Biomimetics is an area of research in which the analysis of structures and functions of natural materials provide a source of inspiration for design and processing concepts for novel synthetic materials. Through biomimetics, it may be possible to establish structural control on a continuous length scale, resulting in superior structures able to withstand the requirements placed upon advanced materials. It is well recognized that biological systems efficiently produce complex and hierarchical structures on the molecular, micrometer, and macro scales with unique properties, and with greater structural control than is possible with synthetic materials. The dynamism of these systems allows the collection and transport of constituents; the nucleation, configuration, and growth of new structures by self-assembly; and the repair and replacement of old and damaged components. These materials include all-organic components such as spider webs and insect cuticles (Fig. 1); inorganic-organic composites, such as seashells (Fig. 2) and bones; all-ceramic composites, such as sea urchin teeth, spines, and other skeletal units (Fig. 3); and inorganic ultrafine magnetic and semiconducting particles produced by bacteria and algae, respectively (Fig. 4).
