Tattoo ink nanoparticles in skin tissue and fibroblasts
Beilstein J. Nanotechnol. 2015, 6, 1183–1191, doi:10.3762/bjnano.6.120
- is widely acknowledged that nanoparticles have higher levels of chemical activity than their larger particle equivalents. However, assessment of the toxicity of tattoo inks has been the subject of little research and ink manufacturers are not obliged to disclose the exact composition of their
- associated pigment particles can be found to leave the skin via its vasculature and enter the lymphatic system (nodes) [3]. Tattoo inks are commonly made up of a mixture of small organic pigments, water and isopropyl alcohol. Surprisingly, manufacturers of tattoo ink are not compelled to reveal the precise
- ingredients or chemical composition of their ink products despite their potential systemic absorption. Black inks are commonly made from soot (carbon black) particles. Tattoo inks can contain polycyclic aromatic hydrocarbons (PAHs) at a range of concentrations, which are reported to be carcinogenic, mutagenic
An insight into the mechanism of charge-transfer of hybrid polymer:ternary/quaternary chalcopyrite colloidal nanocrystals
Beilstein J. Nanotechnol. 2014, 5, 1235–1244, doi:10.3762/bjnano.5.137
- the above observations was provided by investigating the photoluminescence intensities of each of the prepared hybrid nanocomposites of CISe, CIGSe and CZTSe. Emission intensity studies for each of the nanocrystal inks: P3HT were investigated by photoluminescence spectroscopy to study trends of
- . A similar procedure was followed to prepare the CIGSe and CZTSe inks as well as their corresponding polymer nanocomposites with the polymer P3HT. The absorption spectra of the CISe, CIGSe and CZTSe samples were recorded by using a Shimadzu 3101 spectrometer. PL was measured by using a self-assembled
Optical and structural characterization of oleic acid-stabilized CdTe nanocrystals for solution thin film processing
Beilstein J. Nanotechnol. 2014, 5, 881–886, doi:10.3762/bjnano.5.100
- , 350 and 400 °C. On the other hand, oleic acid is a green organic ligand, which has been successfully used in preparing a great variety of colloidal materials [15][25][26], including CdTe quantum dots [27][28][29]. This work presents our early results on the elaboration of CdTe-based inks for potential
Template based precursor route for the synthesis of CuInSe2 nanorod arrays for potential solar cell applications
Beilstein J. Nanotechnol. 2013, 4, 868–874, doi:10.3762/bjnano.4.98
- type CuInSe2 in the current literature [15][16][17]. It has to be mentioned that the morphologies accessible by the liquid precursor route are not restricted to only Q1D nanostructures. Such stable ‘inks’ can also find application in printable photovoltaics or film deposition onto various standard
Direct-write polymer nanolithography in ultra-high vacuum
Beilstein J. Nanotechnol. 2012, 3, 52–56, doi:10.3762/bjnano.3.6
- or modify previously deposited films [5][6]. In the case of DPN, the AFM probe can be used to write a wide range of molecular inks with resolutions down to 15 nm [3][7][8]. However, in conventional DPN writing depends on the intrinsic fluidity of the ink molecules or on the creation of ink fluidity
- using solvents [9]. Unfortunately, inks and solvents that have sufficient intrinsic fluidity for DPN evaporate quickly in vacuum. This paper reports that thermal dip-pen nanolithography (tDPN) [10] can deposit polymer nanostructures from a heated AFM tip in a high vacuum environment (Figure 1b). In tDPN
- point inks such as polymers that also have low volatility and so may be deposited under a vacuum. Results and Discussion Our initial approach for depositing organic inks was to attempt DPN with octadecanethiol (ODT), a classic ink for DPN that reproducibly transfers to the substrate. However, it was
