Abstract (en)
Green nanotechnology enables the conversion of biological systems into
environmentally friendly methods for synthesizing nanomaterials. Green approaches
utilize biological sources as an alternative to the physicochemical creation of
nanoparticles, which involves the use of harmful chemicals and severe settings. By
combining the principles of green chemistry, green nanotechnology, and chemical
engineering may create metal nanoparticles that are both environmentally beneficial and
cost effective, without the need for harmful chemicals during their production.
Therefore, in this study, we used the extract of the traditional Serbian tea Bosiljak
(Ocimum basilicum L.) and Borovnica (Vaccinium myrtillus) extracts to create silver
nanoparticles (AgNPs) in a single step without the use of hazardous chemicals. This
eco-friendly, easy-to-use, and reasonably priced approach uses an aqueous plant extract
as a reducing and stabilizing agent for AgNPs. The NPs synthesized from Bosiljak and
Borovnica were termed as OBTe-AgNPs and VMTe-AgNPs, respectively. UV–Vis
spectroscopy, energy dispersive spectroscopy (EDS), transmission electron microscopy
(TEM), field emission scanning electron microscopy (FESEM), and dynamic light
spectroscopy (DLS) were all used to examine the AgNPs. UV–Vis spectroscopy
displayed surface plasmon resonance (SPR) at 344 nm and 305 nm, respectively for
OBTe-AgNPs and VMTe-AgNPs. The FESEM analysis of OBTe-AgNPs and VMTe-
AgNPs revealed that both processes oval shape with average size of 55 and 52 nm,
respectively. While and TEM analysis revealed that the average size of OBTe-AgNPs
and VMTe-AgNPs was 35 nm and 80 nm, respectively. The anti-cancer ability of
OBTe-AgNPs against human cervical immortalized (HeLa) cancer cells was tested.
While on the other hand, VMTe-AgNPs were used as double action tool as anti-cancer
and anti-atherosclerosis against breast adenocarcinoma epithelial cells (MDA-MB-231)
and human umbilical vein endothelial cells (HUVEC). The results showed that both
AgNPs possess cytotoxic effect in a dose dependent manner. OBTe-AgNPs showed
IC50 value of 21.78 ± 0.68 μg/ml against HeLa cells. While VMTe-AgNPs showed IC50
value of 29.69 ± 1.47 μg/ml and 17.72 ± 1.25 μg/ml against MDA-MB-231 and HUVEC
cells, respectively. Furthermore, the potential of OBTe-AgNPs were incorporated into
nanofibers (NFs) as anti-atherosclerosis agent as well as a new coating material for drug
coated balloons (DCBs). The Ag release study reveals that there is sustainable release
over time from various variations of OBTe-AgNPs-NF. Due to this we saw antiatherosclerosis
potential of these OBTe-AgNPs-NFs when exposed to HUVEC cells. In
conclusion, AgNPs and AgNPs-NF produced via green nanotechnology have the
potential to be used as anti-cancer and anti-atherosclerosis agents. Moreover, AgNPs-
NF acts as a newer coating material for DCBs to treat atherosclerosis and peripheral
artery disease.
Abstract (sr)
Zelena nanotehnologija omogućava pretvaranje bioloških sistema u
ekološki prihvatljive metode za sintezu nanomaterijala. Zeleni pristupi
koriste biološke izvore kao alternativu fizičko-hemijskom kreiranju
nanočestica, što uključuje upotrebu štetnih hemikalija i teške uslove.
Kombinovanjem principa zelene hemije, zelene nanotehnologije i hemijskog
inženjeringa mogu se stvoriti metalne nanočestice koje su i ekološki korisne
i isplative, bez potrebe za štetnim hemikalijama tokom njihove proizvodnje.
Zbog toga smo u ovoj studiji koristili ekstrakt tradicionalnog srpskog čaja
Bosiljak (Ocimum basilicum L.) i ekstrakte Borovnice (Vaccinium myrtillus) za
stvaranje nanočestica srebra (AgNPs) u jednom koraku bez upotrebe opasnih
hemikalija. Ovaj ekološki prihvatljiv pristup, jednostavan za upotrebu i
pristupačne cene, koristi vodeni biljni ekstrakt kao sredstvo za redukciju i
stabilizaciju nanočestica srebra. Nano čestice sintetisane iz Bosiljaka i
Borovnice nazvani su kao OBTe-AgNPs i VMTe-AgNPs, respektivno. UV-Vis
spektroskopija, spektroskopija disperzije energije (EDS), transmisiona
elektronska mikroskopija (TEM), emisiona skenirajuća elektronska
mikroskopija (FESEM) i dinamička svetlosna spektroskopija (DLS) su
korišćeni za ispitivanje AgNPs. UV-Vis spektroskopija je pokazala
površinsku plazmonsku rezonancu (SPR) na 344 nm i 305 nm, respektivno za
OBTe-AgNPs i VMTe-AgNPs. FESEM analiza OBTe-AgNPs i VMTe-AgNPs
otkrila je da oba procesa ovalnog oblika sa prosečnom veličinom od 55 i 52 nm.
Dok i TEM analiza je otkrila da je prosečna veličina OBTe-AgNPs i VMTe-
AgNPs bila 35 nm i 80 nm, respektivno. Testirana je efikasnost OBTe-AgNPs
u odnosu na ćelije kancera i ljudskih imortalizovanih ćelija kancera grlića
materice (HeLa). Dok su, s druge strane, VMTe-AgNPs korišćene kao sredstvo
dvostrukog dejstva kao anti-kancer i anti-ateroskleroza protiv epitelnih
ćelija adenokarcinoma dojke (MDA-MB-231) i endotelnih ćelija humane
pupčane vene (HUVEC). Rezultati su pokazali da obe AgNPs poseduju
citotoksični efekat u zavisnosti od doze. OBTe-AgNPs su pokazali IC50
vrednost od 21,78 ± 0,68 μg/ml prema HeLa ćelijama. Dok su VMTe-AgNPs
pokazali IC50 vrednost od 29,69 ± 1,47 μg/ml i 17,72 ± 1,25 μg/ml u odnosu na
MDA-MB-231 i HUVEC ćelije, respektivno. Štaviše, potencijal OBTe-AgNPs
je ugrađen u nanovlakna (NF) kao agens protiv ateroskleroze, kao i novi
materijal za oblaganje balona obloženih lekovima (DCB). Studija oslobađanja
Ag otkriva da postoji održivo oslobađanje tokom vremena iz različitih
varijacija OBTe-AgNPs-NFs. Zbog toga smo videli antiaterosklerozni
potencijal ovih OBTe-AgNPs-NF kada su bili izloženi HUVEC ćelijama. U
zaključku, AgNPs i AgNPs-NFs proizvedeni preko zelene nanotehnologije imaju
potencijal da se koriste kao agensi protiv raka i ateroskleroze. Štaviše,
AgNPs-NFs deluju kao noviji materijal za oblaganje za DCB za lečenje
ateroskleroze i bolesti perifernih arterija.
