摘要

Currently available approaches to molecular-scale logic gates are summarized and compared.These include:chemically-controlled fluorescent and transmit-tance-based switches concerned with small molecules,DNA oligonucleotides with fluorescence readout,oligo-nucleotide reactions with DNA-based catalysts,chemically-gated photochromies,reversibly denaturable proteins,molecular machines with optical and electronic signals,two-photon fluorophores and multichromophor-ic transient optical switches.The photochemical principles of electron and energy transfer are involved in several of these approaches.More complex molecular logic systems with reconfigurability and superposability provide contrasts with current semiconductor electronics.Integration of simple logic functions to produce more complex ones is also discussed in terms of recent developments.
