Iqiniso lonke nge-nanocosmetics

Ama-creams ama-magic nama-serum, anezinto ezikwazi ukungenelela ezingxenyeni ezijulile ze-epidermis futhi zisebenze ngaphakathi, zilwa ngokuqinile nezibonakaliso zokuguga, kanye nezimbangela zayo ... zithi, inganekwane? Nokho, ngenxa yentuthuko yanamuhla, futhi ikakhulukazi - i-nanotechnology, konke kwaba Ingabe usenakho ukungabaza? Ake ake sibone ukuthi yikuphi.
Ngokuvamile ngelebuli ukhilimu, ungafunda umbhalo othi "izingxenye zithinta kuphela izendlalelo ezingenasici zedermisi." Iqiniso liwukuthi ubukhulu bezinhlayiya eziningi zezinto ezifaka imikhiqizo yezimonyozi zikhulu uma kuqhathaniswa nama-micropores ezigcawini zesikhumba, ngakho-ke angeke zingene ngaphakathi kunezingqimba ezingaphezulu kwe-epidermis. Yingakho izingqondo ezingcono kakhulu zesintu ziye zachitha isikhathi esingaphezu konyaka ukuze zenze imikhiqizo yezimonyo ezingase zifinyelele kuzo.

Okokuqala, ososayensi baqamba ama-liposomes. Ekuqaleni, lezi zimbalwa ezincane, ezikwazi ukungena esikhaleni se-intercellular, zasetshenziselwa ukwelashwa, kodwa ekuqaleni kwawo-1980, izinkampani zezimonyo zamukela i-baton. Ubuchwepheshe obusha bube yimpumelelo emkhakheni wokunakekelwa ukuguga, ngoba amabhola e-liposome agcwele izingxenye eziwusizo awela umzila we-epidermal futhi afinyelela izingqimba ezijulile zesikhumba lapho izibilini zabo ziqedwa khona futhi izinto ezisebenzayo zigijimela emasethini. Ngenxa yama-liposomes, kungenzeka ukuthi kuqinisekiswe ukulondolozwa kangcono kwezithako ezingaqiniseki (isibonelo, ngokushesha ezixutshwe ngamavithamini emoyeni), kodwa ama-liposomes ngokwawo ayengaqiniseki kakhulu: ama-agent ayenayo impilo yeshefu engapheli izinyanga ezingu-12-14. Ngaphezu kwalokho, ngokuvamile imvoluphu yama-liposomes yaqedwa ngaphambi kokuba ifinyelele esidlangalaleni. Kube sekulandelwa uchungechunge lwemizamo yokuthuthukisa ubuchwepheshe, isibonelo, kubonakala, isibonelo, ama-spherulites - ama-multi-layer spheres aqinile, kancane kancane akhipha izithako ezisebenzayo njengoba zifaka isikhumba. Kodwa-ke, inkathi entsha ngempela yafika kuphela ekuthuthukisweni kwe-nanotechnology.

Izindaba zesibukhulu
Uma kuqhathaniswa nama-nanoparticles ("nanos" ekuhunyushweni okuvela kulesiGreki-isisindo), ama-liposomes abonakala njengama-giants amancane: ubukhulu bama-nanosomes asetshenziselwa izimonyo ngokuvamile ngu-10-20 nm, kanti ama-liposomes angama-200-600 nm. Futhi njengoba kuboniswa yizifundo zabososayensi base-Israel, abaqale ukuqala ukuthuthukiswa kwe-nanocosmetics, usayizi obuncane kangaka ubavumela ukuba bafinyelele ekuhlosweni - i-dermis - ngaphandle kokuphazamiseka futhi ngaphandle kokulahlekelwa. Kukhona ama-nanosomes bese uqala umsebenzi wabo: basusa ubuthi, bavuselele ukuvuselelwa kweseli, babuyisele, balwe nezinqubo zokuguga.

Ama-nanosomes alandelwa yi-nanocomplexes - ukugqoka okukhethwa ngokucophelela okukhethwayo, okwakunoma iyiphi ingxenye yayo eyayihlelwa phansi.

Nanopanacea noma nano-usongo?
Ngokucwaninga yiYunivesithi yaseLancaster e-UK, eminyakeni yamuva, amalungelo amalungelo obunikazi ahlobene nama-nanoparticles aphethwe nje kuphela ngemikhiqizo yokunakekela isikhumba nezinwele. Ngokuvamile, abakhiqizi bezimonyozi basebenzisa izinto zabo zemikhiqizo ama-molecule awakwazi ukungena ngaphakathi esikhumbeni. Kodwa-ke, zikhona ezinye - izinhlayiya ezincane kunazo zonke ezingakwazi ukungena emaceleni bese zingena egazini. Yilabo abangaba ososayensi. Ama-nanoparticles ngokuvamile asolisa kakhulu-ngisho noma anezinto ezihlukahlukene zamakhemikhali nezomzimba kunama-molecule of size evamile.

Namuhla akekho ongasho ngokungaqondile ukuthi i-nanocosmetics ayinabungozi ngokuphelele noma, ngokuphambene, iyingozi: ukuphendula le mibuzo, ngaphezu konyaka owodwa wokucwaninga kuyadingeka. Ochwepheshe bayazi ukuthi uma usebenzisa izinto zokwenza izinto, kukhona ingozi yokucabanga. Kodwa abaningi babo abakwazi ukunikeza impendulo engavamile embuzweni wokuthi ngabe kukhona ingozi yangempela. Nakuba kukhona ososayensi abaningi abanengqondo abaqhathanisa nanotechnology nezilo zaseFrankenstein: izingqondo ezinhle kakhulu zesintu azikazi ukuthi zenzani, ngoba isenzo salezi zinhlayiya emzimbeni womuntu sisadingeka sifundwe. Ngakho-ke, izifundo eziningi zibonise ukuthi ama-nanoparticles akwazi ukugqugquzela ukwakheka kwama-radicals mahhala abhubhisa noma aguqule i-DNA yamaseli.

Eminyakeni embalwa edlule, kwakukhona idatha ukuthi, ngokwesibonelo, i-nanoparticles yesiliva (i-antiseptic eyaziwayo kanye nesakhi esithandwayo semikhiqizo eminingi yezithokozi kanye namalungiselelo okusebenza kwangaphandle), uma ingenwe, ingabangela izinqubo eziningana ezimbi, kuhlanganise nokuhlukumeza ezingeni le-DNA. Ngaphezu kuka-nanocosmetics, ososayensi bakhathazekile ngokuphepha kwe-nutraceuticals nama-nanoparticles. Futhi inhlangano ethi "eluhlaza" ngokubanzi ivikela ukuvinjelwa okwesikhashana ekudayiseni kwe-nanocosmetics neminye imikhiqizo - uma nje ukuphepha kokusetshenziswa kwabo kungaboniswa ngokucacile.

Ukuze ugweme isimo sengqondo sokubandlulula, iziqhwa eziningi zezimonyo ezingenayo i-patent eyodwa yama-nanoponponents zigwema ukusetshenziswa kwesiqalo se "nano", besebenzisa ukuphenduka okunjengokuthi "ubuchwepheshe be-microencapsulation", "microparticles" noma "microliposomes".

Ungakwazi, kodwa ngokucophelela?
Namuhla, cishe okweshumi kokutshalwa kwezimali ezilinganisweni zezigidi zamaRandi ezivela embonini ye-nanotechnology kusetshenziselwa ukucwaninga ngokuphepha kwabo kwempilo yabantu kanye nemvelo. Kodwa, ngokwesayensi abaningi, lezi zimali azikwanele.

Enye inkinga ukuthi imiphumela yocwaningo ayidlangalaziwa kakhulu.

I-Nakomponenty namhlanje ingatholakala ekubunjweni kwama-cocktails amaningi we-mesotherapy. Izindlela ezintsha zakamuva ku-nanocosmetology yi-teknoloji ye-Airgent, esekelwe engxenyeni engaphansi kwe-hyaluronic acid, eyakhiwe nge-nanoparticles yezingxenye zokudla okunomsoco. Emva kwenkambiso, ithoni yesikhumba ikhuphuka, imibimbi iyancipha, ukukhiqizwa kwe-collagen kanye ne-elastin kwanda, futhi okubaluleke kakhulu, isikhumba siyaba buhlungu futhi sikhuphuke, futhi ukucwiliswa kwesikhumba okwenzeka ngobudala kungenye yezinkinga ezinkulu okunzima ukulwa nazo ngisho nokuphumelela okuphambili kakhulu kwe-cosmetology yanamuhla .

Enye inqubo ethandwayo i-laser nanoporphyring, lapho i-laser eyenza izinqwaba ezincane esikhumbeni (ngokuqondile, izinhlanzi) zenza izinkinga zesikhumba ngemibimbi, izintambo, izikebhe ezigqamile, ama-pores awandisiwe.

Lokhu kuvuselela okuqondisayo kuvuselela ukuvuselelwa kwamangqamuzana, ukukhiqizwa kwe-collagen ne-elastin, ukukhululeka kwesikhumba kukhishwa, futhi ngokwayo kuyaqina ngokwengeziwe.

I-Creams nezinye imikhiqizo yezitho zomzimba, lapho ama-nanoponponents engaboniswa khona ngesisodwa noma izithako ezimbili, kodwa ayingxenye enkulu yefomula, enhle kakhulu, kepha umphumela wama-aging anti-aging nama-nanocomplexes ufaniswa nomphumela wokuhlinzwa kwepulasitiki: imibimbi yobudala iyanyamalala, i-oval face igxuma. Kodwa-ke, kufanele zikhethwe ngu-dermatocosmetologist ochwepheshe: ngezenzo ezizimele, kunamathuba aphakeme kakhulu ukuthi uzoqala ukudubula kusuka kumathoni onogada ondlunkulu.

Futhi ezivela ezingxenyeni ezingezochwepheshe (eRussia, izimonyo ezinjalo zihlonishwa kakhulu ngokuthi lifinyelela esimisweni sokukhangisa kwenethiwekhi) kunomonakalo omkhulu kunokuhle.

Ngakolunye uhlangothi lwemali - eminyakeni yamuva, isiqalo "nano" sesivele sinemfashini.

Futhi uma ilebula ithi "nanocream" noma "nanoshampun", ngokuvamile kuvame ukuba khona kwayo kwesinye isici se-nanosize, futhi ngezinye izikhathi leli gama liyiqhinga lokukhangisa. Ngakho-ke, uma i-nanocosmetics idonsela ukunakwa kwakho, kungcono ukhethe okuncamekayo kumikhiqizo nedumela. Futhi qiniseka ukulalela ama-dermatocosmetologists, ukukhumbuza ukuthi inomshini osebenzayo nakakhulu kunemikhiqizo yezitho zomzimba, ngakho-ke ayikho indlela ongayenza ngaphandle kwendlela eyodwa kanye nokubonisana kochwepheshe abanekhono!
