Cytotoxicity of molecular
nanomachine treatment for J774A.1 macrophages. Percent cytotoxicity
of macrophage cells measured with an LDH assay at 0.5, 4, and 24 h
exposed to 100 μM MNM without or with light activation. Percent
cytotoxicity was calculated using a low control (natural cell death)
(0%) and a high control (Triton-x induced cell death) (100%) (a) without
MNM (1% DMSO) (p = 0.0282), (b) with 100 μM
of MNM 1 (fast motor) in 1% DMSO (p =
0.0428), (c) with 100 μM of MNM 2 (slow motor)
in 1% DMSO (p = 0.1971), (d) with 100 μM of
MNM 3 (fast motor with TPP, targeting mitochondria) in
1% DMSO (p = 0.8748). The DMSO concentration was
1% because 100 μM MNM was assayed. Results presented are mean
and standard error from four replicates; *p <
0.05.
