Nanogap-engineerable Raman-active nanodumbbells for single-molecule detection

Surface-enhanced Raman scattering has been widely used for chemical sensing, even though the large nonlinearity of the effect makes reproducible sensing difficult. A DNA-based assembly technique now offers a means of precise engineering of gap distances in nanoparticle dumbbells for a robust surface-enhanced Raman sensing of DNA and RNA molecules.

Highly uniform and reproducible surface-enhanced Raman scattering from DNA-tailorable nanoparticles with 1-nm interior gap

Nanoparticles with a gold core and a gold shell separated by a hollow and uniform one-nanometre gap and nanobridges generate a highly stable and reproducible SERS signal.

Atmospheric pressure mass spectrometric imaging of live hippocampal tissue slices with subcellular spatial resolution

Ambient mass spectrometry-based approaches have found application in biology and medicine. Here the authors report a mass spectrometric imaging method (ambient nanoPALDI) for live hippocampal tissues, based on gold nanorodassisted femtosecond laser desorption and subsequent non-thermal plasma induced ionization.

Radionuclide-embedded gold nanoparticles for enhanced dendritic cell-based cancer immunotherapy, sensitive and quantitative tracking of dendritic cells with PET and Cerenkov luminescence

Herein, we provide a simple and straightforward DNA-based radiolabeling chemistry and additional Au shell formation strategy to obtain radionuclide-embedded gold nanoparticles (RIe-AuNPs) with a high radiosensitivity and excellent in vivo stability. The migration of DCs labeled with RIe-AuNPs to draining lymph nodes was monitored very sensitively and for a long time. The biological function of DCs labeled with RIe-AuNP was not altered and it showed strong antitumor immunity. Because of densely conjugated radioisotopes in RIe-AuNPs, we could obtain strong Cerenkov optical signal comparable with that of positron emission tomography.
