Polydopamine-Based Tumor-Targeted Multifunctional Reagents for Computer Tomography/Fluorescence Dual-Mode Bioimaging-Guided Photothermal Therapy

Cited 57|Views4

Abstract

Development of multifunctional diagnosis and treatment reagents is very meaningful in clinical application. Herein, we developed a polydopamine-based (PDA-based) tumor targeted multifunctional reagent by surface-initiated atom transfer radical polymerization (ATRP) strategy. First, the targeted PDA nanoparticles were prepared via combining with folic acid (FA) and dopamine. Then ATRP technology was used to graft the europium(III) complexes onto PDA surface (defined as FEDA). A series of detections revealed that the FEDA nanoparticles had been successfully prepared and exhibited a bright X-ray computer tomography (CT) and photoluminescence (PL) dual-mode imaging efficiency and an excellent photothermal therapy (PTT) effect in vivo/in vitro.

Pretraining has recently greatly promoted the development of natural language processing (NLP)
We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
