Abstract
We are investigating an imaging agent for early detection of colorectal cancer. The agent, named the nanobeacon, is coumarin 6-encapsulated polystyrene nanospheres whose surfaces are covered with poly(N-vinylacetamide) and peanut agglutinin that reduces non-specific interactions with the normal mucosa and exhibits high affinity for terminal sugars of the Thomsen-Friedenreich antigen, which is expressed cancer-specifically on the mucosa, respectively. We expect that cancer can be diagnosed by detecting illumination of intracolonically administered nanobeacon on the mucosal surface. In the present study, biopsied human tissues were used to evaluate the potential use of the nanobeacon in the clinic. Prior to the clinical study, diagnostic capabilities of the nanobeacon for detection of colorectal cancer were validated using 20 production batches whose characteristics were fine-tuned chemically for the purpose. Ex vivo imaging studies on 66 normal and 69 cancer tissues removed from the colons of normal and orthotopic mouse models of human colorectal cancer, respectively, demonstrated that the nanobeacon detected colorectal cancer with excellent capabilities whose rates of true and false positives were 91% and 5%, respectively. In the clinical study, normal and tumor tissues on the large intestinal mucosa were biopsied endoscopically from 11 patients with colorectal tumors. Histological evaluation revealed that 9 patients suffered from cancer and the rest had adenoma. Mean fluorescence intensities of tumor tissues treated with the nanobeacon were significantly higher than those of the corresponding normal tissues. Correlation of magnitude relation of the intensity in individuals was observed in cancer patients with a high probability (89%); however, the probability reduced to 50% in adenoma patients. There was a reasonable likelihood for diagnosis of colorectal cancer by the nanobeacon applied to the mucosa of the large intestine.

Abstract
The Thomsen-Friedenreich (TF) antigen is a tumor-associated antigen consistently expressed on the apical surface of epithelial-based cancer cells, including pancreatic cancer. In this work, we report the development of multimodal imaging probe, the tripolymer fluorescent nanospheres, whose surface was fabricated with peanut agglutinin (PNA) moieties as TF molecular recognition molecules. Here, we demonstrate that the probe is able to detect TF antigen in human pancreatic cancer tissues and differentiate from normal tissue. What is most noteworthy regarding the probe is its ability to visualize tumor margins defined by epithelial TF antigen expression. Further, in vivo preclinical studies using an orthotopic mouse model of pancreatic cancer suggest the potential use of the nanospheres for laparoscopic imaging of pancreatic cancer tumor margins to enhance surgical resection and improve clinical outcomes.
