Special Issue Information

Dear Colleagues,

Many important biological activities are controlled by enzymatic reactions which are quite excellent in many viewpoints. Such biological processes are often carried out in a relatively large peptide molecule, in which several successive processes as well as transportation of input and output molecules are rationally orchestrated. In other words, several key components installed in such enzymes cooperatively drive the processes in a highly sophisticated fashion. The best example is the photosynthesis in nature. Two photosystems, called PSI and PSII, are installed in green plants and are cooperatively working together to photochemically generate high-energy electrons and molecules as well as proton gradient energy, which is ultimately used to drive the ATP synthase. In this context, substantial efforts should be further made to develop artificial molecular hybrids in which more than one key components collaborate to provide some important outcomes.

Studies of sensors and molecular devices in view of such issues are yet to be explored and are expected to provide new directions for devising artificial molecular hybrids with superior overall performance. The present topical issue focuses on the molecular hybrids, such as sensors, molecular devices, molecular machines, etc., that give a response to input stimuli, like light, electron, temperature, pressure, magnetic field, electric field, etc., as well as input chemical stimuli, like gas molecules, substrates, high-energy molecules, etc. Special attention is paid to the cooperative behaviors of several different key components installed within a single molecular hybrid. Realization of a new physical or chemical property arising from the cooperative phenomenon within such hybrids is another issue to be focused.
