Breast-conserving surgery (BCS) is the predominant treatment approach for initial breast cancer. However, due to a lack of effective methods evaluating BCS margins, local recurrence caused by positive margins remains an issue. Accordingly, radiation therapy (RT) is a common modality in patients with advanced breast cancer.

Correction for 'Zn2SnO4:Cr,Eu ultra-small nanoparticles as new near infrared-emitting persistent luminescent nanoprobes for cellular and deep tissue imaging at 800 nm' by Hongwu Zhang et al., Nanoscale, 2017, 9, 8631-8638.

In vivo luminescent imaging in the second biological window (1000-1400 nm, NIR-II) has attracted increasing attention since it can provide high sensitivity to deep tissue in vivo imaging. Herein, we synthesized approximately 10-15 nm-sized NIR-II luminescent nanoparticles (CaF:Nd NPs). Furthermore, co-doped Y was utilized to enhance the NIR-II luminescence of the CaF:Nd NPs via breaking the aggregation of Nd.

Until now, the afterglow emissions of most developed near infrared (NIR)-emitting persistent luminescent nanoparticles (NPLNPs) were located at approximately 700 nm, at the edge of the first tissue transparency window (from 650 to 900 nm), which resulted in relatively low tissue penetration and signal-to-noise ratio (SNR) for in vivo imaging. Herein, 5 nm ZnSnO:Cr,Eu (ZSO) NPLNPs with NIR afterglow emission at 800 nm are synthesized via a direct aqueous-phase synthesis method. The longer NIR afterglow emission of ZSO NPLNPs can easily penetrate approximately 3 cm of pork tissue.

Article Synopsis
  • High-quality near-infrared (NIR) persistent luminescence nanospheres (PLNPs) were created using a straightforward mesoporous template method, resulting in uniform spherical shapes and adjustable sizes.
  • The synthesized nanoparticles feature a composition of SiO(2)/CaMgSi(2)O(6):Eu(2+), Pr(3+), Mn(2+) and can emit NIR light at 660 nm for over an hour.
  • In vivo studies show that the nanoparticles can be tracked in real-time within a mouse's abdomen, demonstrating their potential as effective nanoprobes for imaging as they get metabolized and move from the lymph system to the bladder.

More and more silver nanoparticles (AgNPs) have been released into the aquatic environment due to their widespread use, which may result in harmful effects on aquatic organisms. Environmental risk assessments of AgNPs on aquatic organisms in the natural environment (including light, sound, etc.) are indispensable.
