Abstract:
Cancer is a deadly disease that has become a major global concern. Early detection of cancer biomarkers is crucial to significantly reduce the impact and enable the prompt diagnosis and effective treatment of cancer. The integration of carbon dots (CDs) with metal-organic frameworks (MOFs) has emerged as a promising approach for developing highly selective and sensitive sensors for cancer biomarker detection. CD@MOF composites exhibit remarkable properties due to the synergy between the exceptional optical characteristics of CDs and the unique surface features of MOFs. With the improved properties, such as high surface area, tunable porosity, excellent photoluminescence, and biocompatibility, that these composites possess, they serve as ideal candidates for cancer biomarker sensing. This review dissects the chemistry of CDs and MOFs, and explores recent advancements in CD@MOF-based strategies in the detection of several cancer biomarkers, highlighting their potential as ultrasensitive probes for clinical applications. It also delineates the challenges in the development and future directions in the application of CD@MOF composites as sensors for cancer biomarkers.

Classifying Matter by Composition
According to its composition, the matter can be classified into two broad categories — pure substances and mixtures.
A pure substance is a form of matter that has a constant composition throughout with uniform properties. For example, any sample of sucrose has the same composition and same physical properties, such as melting point, color, and sweetness, regardless of the source from which it is isolated.
A mixture is composed of two or...

Dot Product
In engineering, the dot product of any two vectors is the product of the magnitudes of the vectors and the cosine of the angle between them. It is denoted by a dot symbol between the two vectors.
Consider a vehicle pulling an object along the ground using a rope. If the rope makes an angle with the horizontal axis, the work done can be calculated using the dot product of the force applied and the object's displacement.
The dot...
