“…The size of this exciton is similar to the size of QD ( Figure 5 ), leading to discreet atomic like energy levels and the spatial confinement of the exciton in three dimensions. The discreet atom like energy levels also result in longer lifetime of the excited states ( Mandal and Chakrabarti, 2017 ; Zaini et al, 2020 ).…”

Photodynamic therapy is a promising cancer treatment that induces apoptosis as a result of the interactions between light and a photosensitizing drug. Lately, the emergence of biocompatible nanoparticles has revolutionized the prospects of photodynamic therapy (PDT) in clinical trials. Consequently, a lot of research is now being focused on developing non-toxic, biocompatible nanoparticle-based photosensitizers for effective cancer treatments using PDT. In this regard, semiconducting quantum dots have shown encouraging results. Quantum dots are artificial semiconducting nanocrystals with distinct chemical and physical properties. Their optical properties can be fine-tuned by varying their size, which usually ranges from 1 to 10 nm. They present many advantages over conventional photosensitizers, mainly their emission properties can be manipulated within the near IR region as opposed to the visible region by the former. Consequently, low intensity light can be used to penetrate deeper tissues owing to low scattering in the near IR region. Recently, successful reports on imaging and PDT of cancer using carbon (carbon, graphene based) and metallic (Cd based) based quantum dots are promising. This review aims to summarize the development and the status quo of quantum dots for cancer treatment.

: Internet of Things (IoT) emerges as disruptive innovation and development in the fields of drug delivery and biomedical sciences using on-target active transportation, sensors, wearable devices, real-time diagnostics, etc. Semiconducting fluorescence emitting material, quantum dots on integration with IoT displayed interesting results in healthcare sector especially in hospitals and pathological laboratories. Presently, the integrated system is used to improve productivity without the interference of human and offer cost-effective system. This integrated system can be used for detection of various diseases like epilepsy, cancer, diabetes, etc. and various biomedical applications like energy storage, lights, sensor technology, light filters, etc. The integrated technology is implemented into the field of medicine for simplifying the approaches in therapeutics and diagnostic applications. The collected and analyzed data are further useful for healthcare professionals to find patient-centric solutions. Artificial Intelligence-aided IoT emerges as a novel technology for transmitting and securing the health data. Despite some of the limitations like e-waste and risk of hacking, IoT-based QD system will be considered as a modern healthcare provider with life-saving products for enriching medical quality and real-time accessibility.
