Role of nanotechnology in theranostics and personalized medicines

Various researches have been conducted for the improvement of diagnostics and therapeutic systems of health care. Novel and advanced technologies focus more on diagnosing and identifying diseases and then providing an effective therapy conjugated with the diagnostic agents itself. Theranostics based on nanotherpay with personalized medicines do have better prognosis and prevent turning up of curable disease into fatal one due to late diagnosis, especially for the common poor from the third world nations. In the treatment of cancers, various biofluids and tumors are isolated and then analyzed for various biomarkers such as soluble markers, immune histocomplexes, proteins as products from mutated genes, altered proteins, antigens, or differently expressed proteins. Providing treatment on right time depends very much on right-time diagnosis with high specificity and accuracy. Improved diagnosis helps in prescreening the profile of target molecules to develop biomarkers based on disease-specific therapy. With making it the less expensive, with less off-target toxicity and high efficacy and specificity, with real-time analysis for thorough observation and guidance and studying effects and side effects to develop further therapeutic options. This review focuses more on personalized medicines with theranostic approach.
