Gelatin crosslinking with silicate nanoparticles. (a) Image indicates the injectability and stability of gelatin at 37 °C in presence of NP while gelatin alone liquefies. (b) Image indicates representative bulk gels formed with DTT crosslinked PEG-MAL with incorporated gelatin-silicate NPs. (c) Confocal images of cellular uptake of silicate NP. (d) Cell metabolic activity at increasing dose of silicate NPs.
