Fig. 3. (a) Transmission electron microscopy (TEM, scale bar = 200 nm, arrows indicate aggregated particles), dark-field microscopy (DFM, scale bar = 20 μm) and confocal laser scanning microscopy (CLSM, scale bar = 10 μm) of CD-AuNP (7 nM) and HXL2@CD-AuNP (0.56 μM/7 nM) without or with PNA (70 μM). (b) Dynamic light scattering of CD-AuNP (7 nM) and HXL2@CD-AuNP (0.56 μM/7 nM) without or with PNA (30 μM).
