In vivo near infrared fluorescence imaging and dynamic quantification of pancreatic metastatic tumors using folic acid conjugated biodegradable mesoporous silica nanoparticles

We have developed a novel biodegradable fluorescent imaging probe (bMSN@Cy7.5-FA), which exceptional tumor targeting ability and negligible toxicity, which makes it a highly promising multifunctional nanoplatform for the early diagnosis of cancer.95
