Table 1 Selected characterization (TGA) and functionality quantification data

From: Impact of functional inorganic nanotubes f-INTs-WS2 on hemolysis, platelet function and coagulation

Material Kaiser test (mmol/g) Ellman’ s test (mmol/g) TGA—% weight loss (25–800 °C range) ζ potential value (mV)
INTs-WS2 ~ 3% − 25.0
INTs-WS2COOH 11% − 34.7
INTs-WS2NH2 0.77 19% − 18.9
INTs-WS2SH 0.8 14% − 28.4
INTs-WS2OH 12% − 27.2
INTs-WS2OH: specific characterizing IR data [2683–3190–3525 cm−1]: O–H stretchings set (OH organic species); 1620 and 1520 cm-1: C=O stretchings of carbonyl and amide species; 1520 cm−1: C–H stretchings (saturated aliphatic species)
  1. INTs, inorganic nanotubes; TGA, thermogravimetric analysis—starting INTs-WS2 nanotubes are negatively charged (− 25.0 mV) due to known OH-based defects arising from industrial nanofabrication step
