An Overview on Quantum dot technology in Temperature sensor design
Abstract: Quantumdot (QD) thermometry harnesses the sizedependent electronic structure of semiconductor nanocrystals to translate minute temperature variations into robust optical signals. In this work we present a systematic design framework for QDbased temperature sensors that integrates (i) bandgap engineering through precise colloidal synthesis, (ii) surfacestate passivation to suppress nonradiative pathways, and (iii) a planar photonicreadout architecture compatible with lowcost, CMOSfriendly fabrication. By exploiting the linear redshift of the photoluminescence (PL) peak …

Growth of Cu2O on TCO by SILAR method acts as an alternative buffer electrode layer towards the development of organic solar cell
Abstract: In many types of optoelectronic devices, layer of PEDOT: PSS is sandwiched between the indium-tin oxide (ITO) electrode and the active layer. Buffer PEDOT: PSS provides a well- defined work function which is higher than that of ITO (4.2eV), it smooths the ITO surface and so avoids shorts, and it also protects the active layer from ingress of indium or oxygen, leading to longer device lifetimes. The role of PEDOT: …

Design and Evaluation of Thermo-Responsive Poly(N-isopropylacrylamide)-Based Polymeric Nanoparticles for Temperature-Triggered Intratumoral Release of Doxorubicin in Solid Tumors
Abstract: Thermo-responsive polymeric systems have emerged as promising platforms for targeted intratumoral drug delivery in cancer therapy. This study aimed to develop and evaluate poly(N-isopropylacrylamide) (PNIPAM)-based polymeric nanoparticles as intelligent carriers for temperature-responsive delivery of doxorubicin (DOX) to solid tumors. Nanoparticles were synthesized via free radical polymerization using N-isopropylacrylamide as a thermoresponsive monomer and N,N′-methylenebisacrylamide as a crosslinker, forming a stable network with a tunable lower critical solution temperature (LCST).The optimized …

Modern Biomaterials: Biologically Sensitive Hydrogel Materials
Abstract: Modern biomaterials and biological products are interacting at a more clearly defined interface. Hydrogels, a category of highly hydrated biomaterials, are significant. With interstitial voids that are up to 90% water by weight, hydrogels are made of elastic networks. They are created either physically or chemically by self-assembling building blocks that areeither created artificially or organically. Macromolecules in a range of structures, such as cross-linked polymers, entangled fibrillar networks, or …
