Recent studies on bio-imaging applications of hydrogel, QDs and nanoparticles

Proper monitoring of cell-to-cell and cell-to-matrix interaction or cell behavior inside the animal body or cell morphology, immobilization, labeling, can be visualized through probes labeled hydrogels, quantum dots and nanoparticles as carrier. Recent days doctors face the problems regarding the end result of targeted delivery of the drug which is loaded in the carrier. Keeping in view of recent problems in medical science, this review article discusses different categories of probe labeled cell imaging gels, quantum dots and nanoparticles. The article gives handy information about the role of supramolecular hydrogels, and nanogels in observing activities in very small organisms. Discussion on different quantum dots also included in this article. Their light emitting property have been utilizing in deep tissue imaging. Cell imaging nanoparticles like Silicon NPs, lipid NPs, metal organic framework NPs and polymer-dots have been discussed extensively because of their application through Forster Resonance Energy Transfer to visualize certain protein. This discussion on cell imaging carriers with their applications in monitoring cell activity, detection of unknown biomolecules and enhancement of available fluorescent techniques will give the future course of research plan for researchers to unfold hidden truth of biological reactions and behavior of injected therapeutics inside the human body.
