The rapid yet accurate diagnosis of cancer is a critical issue that poses a great challenge worldwide in the field of life science. However, current clinical biochemical techniques have flaws in terms of complicated conducting procedures, high technical requirement, long detection time and high cost. The development of simpler and more economic tools for the fast blood tests of cancer biomarkers has become a major focus of the academy. Molecular probes have merits in sensing applications owing to their conciseness in construction, fast response and low cost. Their conventional application areas involve environmental analysis and cellular/in vivo imaging. In recent years, the development of molecular probes suitable for probing cancer biomarkers has become a vividly new multidisciplinary research field. Here we summarize the construction strategies of these probes and highlight their diagnostic efficiency for cancer biomarkers. This article aims at spurring the diversification of simple and effective molecular probes for the detection cancer biomarkers, accelerating the progress of cancer blood tests by the combination of chemical techniques with medicinal science.
