Summary
Researchers developed a simple method to create smart nanoscale metal-organic framework (NMOF) nanoplatforms for precise, imaging-guided chemotherapy. This versatile strategy enhances biocompatibility, enables active tumor targeting, and controls drug release for improved cancer treatment.
Area of Science:
- Materials Science
- Nanotechnology
- Biomedical Engineering
Background:
- Precise imaging-guided tumor treatment requires theranostic platforms with good biocompatibility, active targeting, and stimulus-responsive release.
- Current fabrication methods for smart theranostic platforms are often complex and time-consuming.
Purpose of the Study:
- To develop a universal and facile strategy for fabricating smart nanoscale metal-organic framework (NMOF)-based nanoplatforms for imaging-guided precise chemotherapy.
- To demonstrate the potential of these nanoplatforms for active tumor targeting, improved biocompatibility, and controlled drug release.
Main Methods:
- Utilized 5-boronobenzene-1,3-dicarboxylic acid (BBDC) as a ligand and Gd3+ as metal nodes to create NMOFs.
- Employed reversible diol-borate condensation for glucose coating on NMOFs to enhance biocompatibility and enable tumor targeting via glucose transporter interaction.
- Investigated the pH-responsive nature of the glucose layer as a gatekeeper to prevent premature drug leakage.
Main Results:
- Successfully fabricated a smart magnetic resonance (MR) imaging-guided drug-delivery system using the proposed strategy.
- Demonstrated active tumor targeting and controlled drug release, leading to effective MR imaging-guided tumor-targeted precise chemotherapy.
- Extended the strategy to create other MOF-glucose composites for diverse applications, including Yb-MOFs-Glu for X-ray computed tomography imaging.
Conclusions:
- The facile and universal strategy using BBDC offers a simple method to fabricate multifunctional NMOF theranostic platforms.
- This approach provides a new pathway for developing advanced nanoagents for precision medicine, combining imaging and therapy.
- The developed nanoplatforms show significant promise for improving cancer treatment through enhanced targeting and controlled drug delivery.

Group 1 elements are soft and shiny metallic solids. They are malleable, ductile, and good conductors of heat and electricity. The melting points of the alkali metals are unusually low for metals and decrease going down the group, while the density increases going down the group with the exception of potassium (Table 1).

Metallic bonds are formed between two metal atoms. A simplified model to describe metallic bonding has been developed by Paul Drüde called the “Electron Sea Model”.

Metallic solids such as crystals of copper, aluminum, and iron are formed by metal atoms. The structure of metallic crystals is often described as a uniform distribution of atomic nuclei within a “sea” of delocalized electrons. The atoms within such a metallic solid are held together by a unique force known as metallic bonding that gives rise to many useful and varied bulk properties.

The hemoglobin in the blood, the chlorophyll in green plants, vitamin B-12, and the catalyst used in the manufacture of polyethylene all contain coordination compounds. Ions of the metals, especially the transition metals, are likely to form complexes.
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...

03:37Uncertainty in Measurement: Accuracy and Precision
101.1K
Scientists typically make repeated measurements of a quantity to ensure the quality of their findings and to evaluate both the precision and the accuracy of their results. Measurements are said to be precise if they yield very similar results when repeated in the same manner. A measurement is considered accurate if it yields a result that is very close to the true or the accepted value. Precise values agree with each other; accurate values agree with a true value.

02:58Properties of Transition Metals
29.8K
Transition metals are defined as those elements that have partially filled d orbitals. As shown in Figure 1, the d-block elements in groups 3–12 are transition elements. The f-block elements, also called inner transition metals (the lanthanides and actinides), also meet this criterion because the d orbital is partially occupied before the f orbitals.
