Check if the same lab product or an alternative is used in the 5 most similar protocols
Human skin fibroblasts (commercial cell line GM5565; from ATCC/Coriell Institute, Camden, NJ, USA) were cultured in a medium consisting of Minimum Essential Medium Alpha (Gibco/Thermo Fisher Scientific) and supplemented with 10% (v/v) fetal bovine serum (FBS). Cells were maintained in T-50 flasks with 10 mL of media, grown at 37 °C and 5% CO2. The media contain less than 0.5 µM of indium ions, as characterized by inductively coupled plasma mass spectrometry. Two different media solutions were prepared: indium-free media, containing only the chemical components described above and media supplemented with 3.2 mM of indium (III) chloride (99.99%, Sigma-Aldrich, Oakville, ON, Canada). Prior to cell seeding, nanocomposite substrates were sterilized with 2 mL of 70% ethanol for 1 min and then air dried and rinsed with 2 mL of sterile phosphate-buffered saline (PBS) twice to eliminate any ethanol residue. Substrates were inoculated with media containing 2–9 × 104 cells/mL and incubated in 6-well tissue culture plates (VWR® Multiwell Cell Culture Plates, 10062-892) for 24–48 h at 37 °C and 5% CO2.

The ultraviolet and visible (UV-Vis) spectra of materials were obtained with a UV-Vis spectrometer (UV-2450 from Shimadzu). Photoluminescence spectra of NCs were acquired using a spectrophotometer (RF-5301PC from Shimadzu). Transmission electron microscope (TEM) images and Energy-dispersive X-ray (EDX) spectra were acquired using a JEOL analytical transmission electron microscope (model JEM 2100F operated with a 200 kV acceleration voltage) equipped with an Oxford Energy-Dispersive X-ray (EDX) spectrometer. Time-resolved photoluminescence lifetimes were measured by a Horiba Jobin Yvon Fluorolog-3 with a QY accessory and a time-correlated single-photon counting (TCSPC) spectrometer. The continuous excitation source was a 150 W ozone-free xenon arc-lamp. A pulsed xenon lamp or NanoLED (N-405L or N-300) was utilized as the excitation source for the photoluminescence decay measurement.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
