Abstract
The application of nanoparticles (NPs) offers new prospects for the early detection and effective therapy of colorectal cancer (CRC). Various NPs have been designed and explored as diagnostic and/or therapeutic drug delivery vehicles. To achieve selective treatment and to reduce toxicity, these nanoparticles are usually endowed with targeting abilities. Passive targeting is based on the extravasation and enhanced permeability and retention effect of tumors, while active targeting always involves binding to specific ligands that are recognizable by CRC tissues, such as vascular endothelial growth factor, folate, monoclonal antibodies (mAbs), aptamers, and membrane penetrating peptides. In addition, contrast agents, such as gadolinium complexes and iron oxide particles, can be introduced into the delivery system to enable MR imaging and lesion detection. Furthermore, smart carriers have been gradually applied to the delivery system. These carriers are designed to respond to certain changes in the bio-environment and release encapsulated contents on demand, thus achieving effective drug concentrations at tumor sites. This review focuses on recent advances of NP technology for the targeted diagnosis and treatment of CRC and aims to unveil the emerging possibilities of using nanocarriers to enhance therapeutic applications.

Advances in Cancer Biomarkers and Potential Drug Targets: From Diagnosis to Therapy
Cancer biomarkers play a crucial role in the diagnosis, prognosis, and treatment of cancer. They provide valuable information for cancer detection, risk assessment, treatment selection, and monitoring response to therapy. With advancements in molecular biology and high-throughput technologies, there has been an increasing interest in identifying and characterizing cancer biomarkers ...read more
Novel Therapeutic Approaches to Target Drug Resistant Tumors
With the development of disciplines such as chemical biology and molecular biology, the genes or proteins closely related to tumor occurrence and development have gradually become clear. Targeted therapies targeting these genes or proteins provide more effective methods for tumor treatment. Tumor targeted drugs generally only act on specific targets ...read more
ROLE OF IMMUNE AND GENOTOXIC RESPONSE BIOMARKERS IN TUMOR MICROENVIRONMENT IN CANCER DIAGNOSIS AND TREATMENT
Biological biomarkers have been used in medical research as an indicator of a normal or abnormal process inside the body, or of a disease. Nowadays, various researchers are in process to explore and investigate the biological markers for the early assessment of cancer. DNA Damage response (DDR) pathways and immune ...read more
Targeting the battlefield between host and tumor: basic research and clinical practice on reshaping tumor immune microenvironment
Immune system protects host against malignant tumors through effector cells and molecules. Cancer development and its response to therapy are regulated by inflammation, which either promotes or suppresses cancer progression. Chronic inflammation facilitates cancer progression and treatment resistance, whereas induction of acute inflammatory reactions often lead to anti-cancer immune responses. ...read more
