“…The cytotoxicity of purified pyomelanin was determined both by the MTT (3‐[4,5‐dimethylthiazol‐2‐yl]‐2,5‐diphenyltetrazolium bromide) assay and orange‐ethidium bromide staining (AO/EtBr). Mouse fibroblast NIH3T3 and human keratinocytes HaCaT were grown in 96 well plates as stated in Section Cells, media, chemicals and culture conditions .…”

In this study, we report on the ability of the yeast Yarrowia lipolytica W29 to produce an extracellular melanin‐like brown pigment at high yield (0.5 mg/ml) in culture medium supplemented with L‐tyrosine. This pigment has been characterized as pyomelanin and its synthesis was found to occur by the so‐called HGA‐melanin pathway. The purified pyomelanin was found embedded with antioxidant properties as it exhibited a radical scavenging activity toward 1,1‐diphenyl‐2‐picrylhydrazyl (DPPH) with IC50 of 230 μg/ml. It was also characterized as noncytotoxic toward two mammalian cell lines, namely the mouse fibroblast NIH3T3 and human keratinocytes HaCaT. When blended with different commercial sunscreens, the purified pyomelanin increased significantly the sun protection factor (SPF) value, highlighting its potential utilization as UV‐filter in cosmetic preparations.

“…The release profile of the sponge-like and finger-like side of the membranes was analysed by detecting the water-soluble components of TTO (terpinen-4-ol, α-terpineol, and 1,8-cineole) 62 released in a water bath UV-visible spectroscopy ( Figure S1). 58,63 The sponge-like side exhibited a faster release (72 and 81% after 1 and 2 hours, respectively) than the finger-like side (54 and 70% after 1 and 2 hours, respectively). For antibacterial tests, all membranes were loaded with the essential oil from the side with open porosity (sponge-like morphology), as schematised in Fig.…”

“…In another study, porous films of PVDF and calcium phosphate containing eucalyptus and tea tree essential oils have been studied as delivery devices. 58 They showed antibacterial activity against E. coli and Staphylococcus aureus and cytocompatibility for mouse mesenchymal cells (C3HIOT1) and mouse myoblasts (C2C12). Composite membranes of poly[(vinylidene fluoride)-co-trifluoroethylene] (P(VDF-TrFE) and NaY zeolite have been prepared by solvent casting for the controlled release of Ibuprofen (IBU).…”

“…They were proposed for nerve tissue regeneration, because of their ability to promote attachment and proliferation of PC12 cells (a rat neuronal cell line). In another study, porous films of PVDF and calcium phosphate (CaP) containing eucalyptus and tea tree essential oils have been studied as delivery devices 58. They showed antibacterial activity against E. coli and S. aureus and cytocompatibility for mouse mesenchymal cells (C3HIOT1) and mouse myoblasts (C2C12).…”

Bioinspired Poly(vinylidene fluoride) Membranes with Directional Release of Therapeutic Essential Oils

et al. 2018

Here, the morphology of polypore fungi has inspired the fabrication of poly(vinylidene fluoride) (PVDF) membranes with dual porosity by nonsolvent-induced phase separation (NIPS). The fruiting body of such microorganisms is constituted of two distinct regions, finger- and sponge-like structures, which have been successfully mimicked by controlling the coagulation bath temperature during the NIPS process. The use of water at 10 °C as coagulant resulted in membranes with the highest finger-like/sponge-like ratio (53% of the total membrane thickness), while water at 90 °C allowed the formation of macrovoid-free membranes. The microchannels and the asymmetric porosity were used to enhance the oil sorption capacity of the PVDF membranes and to achieve directional release of therapeutic essential oils. These PVDF membranes with easily tuned asymmetric channel-like porosity and controlled pore size are ideal candidates for drug delivery applications.

IR spectroscopic and photoluminescence studies of plasma polymerized organic thin films based on tea tree oil

et al. 2020

Plasma-assisted synthesis of transparent, environment friendly, lightweight, flexible and stable organic thin films from naturally occurring precursors were emerging as potential candidates for organic semiconductor industry. In the present study, tea tree (Malaleuca alternifolia) oil based polymer thin films were deposited on glass and silicon substrate by using radio frequency plasma polymerization technique. The polymer thin films were characterized with atomic force microscopy (AFM) and Fourier transform infrared (FTIR) spectroscopy techniques. AFM images indicate the formation of homogenous film on the substrate surface. FTIR spectra gives bands related to methyl and methylene groups which confirms the formation of chain branching in the polymer films. Relatively intense infrared (IR) bands obtained from films deposited on glass substrate reveals that glass substrate is more favourable for the growth of polymers than silicon substrate. Optical band gap of the polymerized thin film on glass substrate was estimated using Tauc plot which gives a value of 3.19 eV, indicating the semiconducting nature of the material. Photoluminescence (PL) emission in the yellow region were observed from both the samples and its CIE colour coordinates also matches with yellow emission. Broad visible emission observed in the wavelength range 465-695 nm indicates the presence of multichromophores in the polymer film. Samples also gives IR emission in the wavelength range of 850-1090 nm, upon excitation with a wavelength of 785 nm contributed to polaronic transitions.
