We developed a high-resolution photoacoustic microscopy (PAM) system with a near-infrared (NIR) laser to noninvasively monitor the distribution of gold nanostar (GNS) in blood vessels, liver and spleen in mice. Photoacoustic images of organs at deep depths were continuously acquired in vivo every 30 minutes after a single dose of GNS by tail vein injection.(More)
Conventional evaluation methods of chemotherapeutic efficacy such as tissue biopsy and anatomical measurement are either invasive with potential complications or dilatory to capture the rapid pathological changes. Here, a sensitive and resolution-scalable photoacoustic microscopy (PAM) with theranostic nanoformulation was developed to noninvasively monitor(More)
In this paper, we propose a fine tuneable capacity and invisibility novel blind watermarking method for 3D models with arbitrary topology in spatial domain. Our atermarking approach is based on a novel four-points sets construction and selection scheme to embed watermark in the vertices of the 3D models. Experimental results show that the capacity and(More)
Leucine-rich repeat receptor-like kinases (LRR-RLKs) represent a large class of proteins in regulating plant development and immunity. The LRR-RLK XA21 confers resistance to the bacterial disease caused by the pathogen of Xanthomonas oryzae pv. oryzae (Xoo). Several XA21 binding proteins have been characterized, however the early events governing XA21(More)
