Noble metal nanomaterials for the diagnosis and treatment of hematological malignancies.

BACKGROUND

Recently, the incidence of hematological malignancy, such as various leukemias, multiple myeloma and lymphoma, has revealed an increasing tendency, exhibiting a major impact on human health. Most of the available anti-cancer drugs, however, possess high non-targeted accumulation, dosage-associated toxicity, fast elimination, and lack specificity towards tumors, which restrict their utilization in clinical therapy. This extends also to cancer diagnosis where there is a lack of predictive biomarkers.

OBJECT

Noble metal nanomaterials (NM NMs) have the potential to overcome these shortcomings due to several characteristics including ease of synthesis, ultra-small size, easy surface modification and specific physicochemical properties. At present, gold-, silver- and platinum-based nanomaterials have been employed in the tracing and treatment of hematopoietic tumors through direct individual endocytosis or in innovative drug delivery systems (DDS) by conjugation with other targeting biomolecules.

PURPOSE

In this mini review, we focus on the use of localized surface plasmon resonance (LSPR)-/surface-enhanced Raman scattering (SERS)- and fluorescence-based diagnosis of NM NMs in the hematological malignancies. Furthermore, the treatment of hematological malignancies utilized the NM NMs or NM NMs-based therapy technology in the chemotherapy, targeted therapy, and photothermal therapy are depicted in depth. The construction of effective and promising NM NMs or NM NMs- dependent theranostic methodology has the potential to provide interdisciplinary knowledge in the development of clinical tracing, diagnosis and treatment of refractory hematological diseases.
