Immune escape mechanisms revealed by multifunctional nanoprobes targeting PD‐L1 in hepatic cancer progression

VIEW, EarlyView.
The ICGB@Apt nanoprobes are designed to specifically recognize immune checkpoint molecules such as PD‐L1, thereby enabling precise monitoring of the progression from liver cirrhosis to HC. By binding to PD‐L1 on tumor cells, ICGB@Apt visualizes immune escape events and tumor metastasis while simultaneously reflecting the dynamic interaction between ...

Direct observation of elemental segregation in InGaN nanowires by X‐ray nanoprobe

physica status solidi (RRL) – Rapid Research Letters, 2011
AbstractUsing synchrotron radiation nanoprobe, this work reports on the elemental distribution in single Inx Ga1–xN nanowires (NWs) grown by molecular beam epitaxy directly on Si(111) substrates. Single NWs dispersed on Al covered sapphire were characterized by nano‐X‐ray fluorescence, Raman scattering and photoluminescence spectroscopy. Both Ga and In
