Biosensors for cancer theranostics

Cancer is one of the most harmful and deadliest diseases nowadays owing to its high infectious and mortality rate around the world. The risk of cancer exposure increases day today as a result of unhealthy and lavished lifestyle habits, occupational exposures, alcohol intake, and smoking practices. A novel approach by rapid detection at the beginning stage screening is important in this era for public health, despite the fact that numerous technologies are revolutionized for the cancer diagnosis.Also at a smaller size, cancerous lesions detection is very much important because the current techniques fail in this regard. The biosensors in the market provide the necessary features for effective and rapid determination of cancer infections in the human body. The excellent results of a biosensor such as reliability, fast with accuracy, can be effectively customized for the diagnosis of cancer biomarkers in the human body. Here in this review, we focussed on understanding biosensors, current advancements including various materials, and advantages over the conventional techniques followed by future perspectives. Finally, we wrap upby some suggestions and improvizations that might help with the quick identification of cancer disorders in the future. © 2022 The Author(s)
