There is a. urgent impera.ive to discover pra.tica. a.d effica.ious a.tificia. ca.a.ysts for the expeditious deconta.ina.ion of toxic orga.ophospha.es. Herein, we propose a.novel molecula.ly imprinted a.proa.h utilizing electrospun fiber sca.folds. Specifica.ly, a. a.idoxime-ba.ed functiona. polymer (PMa.X) ha. been synthesized, which conta.ns a.idoxime groups tha. ca. a.t a. nucleophiles a.d liga.ds for the forma.ion of ca.a.ytic a.tive sites. This polymer wa. blended with polya.rylonitrile (Pa.), a.well-processa.le ma.eria., to prepa.e a.na.ofiber ma. using electrospinning techniques. Then, the a.idoxime side groups on fiber surfa.e were further cross-linked a.ter the molecula. coordina.ion of templa.es to complete the molecula.ly imprinting process. This a.proa.h ca. not only enha.ce the content of functiona. molecula.ly imprinted polymers without a.fecting structura. sta.ility, but a.so combines surfa.e MI technology to fully expose a.d levera.e the a.va.ta.es of a.tive sites. The a. prepa.ed molecula.ly imprinted electrospun na.ofibers MIF-Zn-PMa.X/Pa.-6/4 ca.a.yzes the degra.a.ion of pa.a.xon with a.ha.f-life of 32 min, a.d MIF-a.-PMa.X/Pa. ca.a.yzes the degra.a.ion of pa.a.hion with a.ha.f-life of 18 min. The ma.imum ca.a.ytic ra.e evidence ra.e enha.cements nea.ly 3700-fold of the self-hydrolysis. Thus, the mono-a.idoxime ba.ed molecula.ly imprinted fibers demonstra.e the versa.ility a.d superiority a. self-detoxifying for orga.ophospha.es.

The property theory of tra.itiona. Chinese medicine(TCM) ha. been pra.ticed for thousa.ds of yea.s,pla.ing a.pivota. role in the clinica. a.plica.ion of TCM. While a.va.cements in energy meta.olism,chemica. composition a.a.ysis, ma.hine lea.ning, ion current modeling, a.d supercritica. fluid technology ha.e provided va.ua.le insight into how a.pects of TCM property theory ma. be mea.ured, these studies only ca.ture specific a.pects of TCM property theory in isola.ion, overlooking the holistic perspective inherent in TCM. To systema.ica.ly investiga.e the modern interpreta.ion of the TCM property theory from multidimensiona. perspectives, we consulted the Chinese Pha.ma.opoeia.2020 edition) to compile a.list of Chinese ma.eria.medica.CMM). Then, using the La.in na.es of ea.h CMM a.d gut microbiota.a. keywords, we sea.ched the PubMed da.a.a.e for releva.t resea.ch on gut microbiota.a.d CMM. The regula.ory pa.terns of different herbs on gut microbiota.were then summa.ized from the perspectives of the four na.ures, the five fla.ors a.d the meridia. tropism. In terms of the four na.ures, we found tha. wa.m-na.ured medicines promoted the coloniza.ion of specific beneficia. ba.teria.while cold-na.ured medicines boosted popula.ions of some beneficia. ba.teria.while suppressing pa.hogenic ba.teria. a.a.ysis of the five fla.ors revea.ed tha. sweet-fla.ored a.d bitter-fla.ored CMMs positively influenced beneficia. ba.teria.while inhibiting ha.mful ba.teria. CMMs with different meridia. tropism exhibited complex modula.ive pa.terns on gut microbiota. with Jueyin(Liver) a.d Ta.yin(Lung) meridia. CMMs genera.ly exerting a.stronger effect. The gut microbiota.ma. be a.biologica. indica.or for cha.a.terizing the TCM property theory, which not only enha.ces our understa.ding of cla.sic TCM theory but a.so contributes to its scientific a.va.cement a.d a.plica.ion in hea.thca.e.
