Molecular imprinting technology（MIT）is a kind of new-emerging polymerizing technology with specific selectivity and affinity ability, An elucidation on the basic principles, and the broad applications of molecularly imprinted polymers (MIPs) in some fields are given in this paper. It also gives an overview of some recent development in the field and offers an insight into how the area is likely to evolve in the future.

Haedoxans are a series of sesquilignan natural products isolated from the traditional insecticidal plant Phryma leptostachya. Given their significant insecticidal activity, haedoxans and related analogs have been considered as potential agents for plant defense. Moreover, these compounds also exhibit promising antifungal, antibacterial, and anticancer activities. The present paper is a review of the structure, biological activity, and chemical synthesis of naturally occurring haedoxan-like molecules.

The surface of commercial TiO2 nanoparticles was modified by titanate coupling agent, JSC(isopropyl tricarboxytate titanate), FTIR spectrum confirmed that organic functional groups were successfully grafted onto the surface of TiO2 nanoparticles. The SEM micrographs indicated that the aggregation of modified TiO2 was reduced and most of the particles were approximately 20 nm.

Molecular imprinting technology is a kind of new-emerging polymerizing technology, which produces molecule recognition materials with high selectivity an affinity. MIPs were synthesized using acrylic amide as functional monomers, azodiisobutyronitrile as initiator, and lutelin as template molecules. The absorption capability of MIPs wans studied. The results showed that the imprinting efficiency is 97.9%.
