Transition metal sulfides/transition metal phosphides (TMS/TMP) has shown great potential in cancer diagnosis and treatment due to its unique structural, optical, acoustic and magnetic properties. TMS/TMP can be formed from sulfur/phosphorus source and metal into binary compounds, or from the interaction of hydrogen sulfide (or hydrogen sulfuric acid) with metal oxides or hydroxides. It has a series of unique properties, such as high conductivity, metalloid properties, a variety of valence states and adjustable structure and so on. These advantages make it have great potential in biomedical applications, such as diagnostic imaging, disease therapy and drug/gene delivery. This review presents the latest research progress of TMS/TMP on tumor imaging, diagnosis and treatment. Here, we first illustrate the synthesis approaches and surface modification of TMS/TMP. Then, its emerging applications in tumor diagnosis and therapy are highlighted. Moreover, the challenges of TMS/TMP-mediated diagnosis/treat are provided and the prospective for this field are discussed.

“…Similarly, Miao et al synthesized Cd 3 P 2 QDs by the liquid phase method, which exhibited photoluminescent wavelengths spanning across the visible red light to the NIR spectral region. [10] The coating of PS and SiO 2 could enhance the optical and chemical stability of Cd 3 P 2 QDs, which is conducive to further biolabeling applications. In addition to ultrasmall InP and Cd 3 P 2 QDs, hydroxyapatite (Ca 10 (PO 4 ) 6 (OH) 2 ) doped with lanthanide ions, such as Eu 3+ , Tb 3+ , Gd 3+ , La 3+ , and Ce 3+ , have also been prepared for biolabeling.…”

“…[ 19 ] The excellent optical, magnetic, and catalytic properties make Metal‐P NMs can be used as multifunctional diagnostic (photoacoustic imaging (PAI), fluorescent imaging (FI), magnetic resonance imaging (MRI), and nuclear imaging) and therapeutic (photothermal therapy (PTT), chemodynamic therapy (CDT), photodynamic therapy (PDT), and immunotherapy) agents for tumor theranostics. [ 5–19 ] Moreover, Metal‐P NMs are also suitable to be nanocarriers for delivering drugs owing to their degradable properties. [ 12 ] As a good medicine carrier, Metal‐P NMs can be loaded on chemotherapy drugs, photosensitizers, sonosensitizers, Fenton agents, genes, proteins, and various imaging contrast agents to achieve the integration of multimodal imaging and therapies.…”

to their unique physical and chemical properties. [2] Therefore, to improve the efficacy of early diagnosis and cure rate, many types of inorganic nanomaterials have been prepared for tumor therapy, such as elemental substances (Au, Ag, Pt, etc.), [3a-c] chemical compounds (carbon-, silic-, nitrogen-, phosphorus-based nanomaterials, etc), [3d-f ] metal organic frameworks, and so on. [3g,h] Among above inorganic nanoterials, phosphorus-based nanomaterials have broad application prospects in the field of biomedicine because phosphorus is one of the crucial component elements in our body and it could maintain vital activities in different aspects: [4] 1) Phosphorus is one of the basic elements in protein and phospholipid and it is necessary to maintain the integrity of cell membranes and perform cell functions. 2) Phosphorus is also a necessary component of phosphate in body fluids and it could regulate the pH balance and energy metabolism. 3) Phosphorus is one of the basic elements of our bone for supporting our body. Among the phosphorus-based nanomaterials, metal phosphorus-based nanomaterials (Metal-P NMs) have been widely explored and studied in cancer diagnosis and therapy due to their unique merits, such as excellent optical absorption, inherent magnetic properties, and biodegradable properties.Metal-P NMs mainly include metal phosphide nanomaterials (e.g., ferrous phosphide (Fe 2 P), [5] iron phosphide (FeP), [6] cuprous phosphide (Cu 3 P), [7] trinickel monophosphide (Ni 3 P), [8] dicobalt phosphide (Co 2 P), [9a-c] cobalt phosphides (CoP), [9d,e] cadmium phosphide (Cd 3 P 2 ), [10] and indium phosphide (InP) [11] ), metal phosphate nanomaterials (e.g., calcium phosphate (CaP), [12] calcium bisphosphonate (CaBP), [13] manganese phosphate (MnP), [14,50] zirconium phosphate (ZrP), [15] magnesium phosphate (MgP), [16] gadolinium phosphate (GdPO 4 ), [17] and copper hydroxyphosphate (Cu 2 (OH)PO 4 ) [18] ), and metalblack phosphorus (Metal-BP) nanocomposite. [19] The excellent optical, magnetic, and catalytic properties make Metal-P NMs can be used as multifunctional diagnostic (photoacoustic imaging (PAI), fluorescent imaging (FI), magnetic resonance imaging (MRI), and nuclear imaging) and therapeutic (photothermal therapy (PTT), chemodynamic therapy (CDT), photodynamic therapy (PDT), and immunotherapy) agents for tumor theranostics. [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] Moreover, Metal-P NMs are also suitable to Metal phosphorus-based nanomaterials (Metal-P NMs) including metal phosphate nanomaterials, metal phosphide nanomaterials, and metal-black phosphorus (Metal-BP) nanocomposite are widely used in the field of biomedicine owing to their excellent physical and chemical properties, biocompatibility, and biodegradability. In recent years, metal phosphate nanomaterials and Metal-BP nanocomposite acted as medicine delivery system have made breakthroughs in tumor diagnosis including magnetic resonance imaging, fluorescence imaging, photoacoustic imaging, nuclear imaging, and therapies ...

Cd3P2/Zn3P2 Core-Shell Nanocrystals: Synthesis and Optical Properties

et al. 2022

View full text Add to dashboard Cite

II–V semiconductor nanocrystals such as Cd3P2 and Zn3P2 have enormous potential as materials in next-generation optoelectronic devices requiring active optical properties across the visible and infrared range. To date, this potential has been unfulfilled due to their inherent instability with respect to air and moisture. Core-shell system Cd3P2/Zn3P2 is synthesized and studied from structural (morphology, crystallinity, shell diameter), chemical (composition of core, shell, and ligand sphere), and optical perspectives (absorbance, emission-steady state and time resolved, quantum yield, and air stability). The improvements achieved by coating with Zn3P2 are likely due to its identical crystal structure to Cd3P2 (tetragonal), highlighting the key role crystallographic concerns play in creating cutting edge core-shell NCs.
