“…PTT typically uses photothermal agents that have accumulated at disease areas as energy absorbers to produce local heat when exposed to NIR light, which causes aberrant cells to undergo apoptosis or necrosis [83]. PTT is a helpful modality for treating a variety of diseases because of its advantages of simple operation, little invasiveness, short therapy duration, quick recovery, minimized side effects, and low recurrence.…”

Biomaterials technology has advanced significantly in recent years and 2D nanostructures have played a key role in this advancement. A new ceramic 2D nanomaterial, MXene, made up of transition metal carbides, carbonitrides and nitrides with a planar layout that was produced by etching away “A” from a ceramic phase called “MAX”, has emerged to overcome the shortcomings of traditional biomaterials. MXene is used inadequately in biomedical applications due to its weak stability in physiological conditions, lack of prolonged and low biodegradability, and self‐controlled drug release. These drawbacks have given rise to the idea of using MXene/Polymer nano composites, due to their major properties like large surface area, metallic conductivity, biocompatibility, hydrophilicity, and size tunability. Polymer functionalization is possible by the surface‐available functional groups. This review has been done to focus on cutting‐edge examples such as polymer functionalized composites MXene for the developing field of biomedical applications. These applications consist of precise and prolonged antimicrobial activity, bio sensing, therapeutics, drug delivery, contrast‐enhanced diagnostic imaging, tissue engineering, flexible electronics, and bone regeneration.

“…10 The electrochemical sensor method can be a good alternative to overcome some of the disadvantages of these techniques (time-consuming, difficulty of operation, and high cost). In the design of electrochemical sensors, conductive polymers, metal nanoparticles, metal oxide nanoparticles, and carbon-based nanomaterials are used as sensing materials to enhance the sensitivity, stability, and reproducibility of the electrode, 11 one of which is transition metal molybdates.…”

Melatonin is an important hormone that is clinically significant due to its physiological role, making its detection in real samples crucial for monitoring body function. Compared to other traditional approaches, electrochemical sensors have advantages such as high sensitivity, point-of-care analysis, rapid response time, ease of use, and cost-effectiveness. Recently, natural polymer-based biocomposites such as chitosan, gum acacia, xanthan gum, and chitinhave been employed due to their low cost, biocompatibility, and high surface area for biosensing applications. We have investigated Tungsten oxide (WO3) nanospheres decorated with functionalized chitosan (FCH) for the detection of melatonin. The functionalization of chitosan introduced plentiful amine groups and inter-hydrogen bonding provided necessary stability for the formation of WO3/FCH biocomposite. Further, the electroanalysis confirmed the excellent electrocatalytic performance of the biocomposite towards melatonin in with a limit of detection of 4.9 nM. The proposed nanocomposite exhibited excellent selectivity, reproducibility, stability, and its practical reliability was evaluated real samples. Herein, functionalization of introduced large density of amine groups that offered efficient binding affinity with WO3.and improved the conductivity of the nanocomposite for a highly sensitive melatonin detection. The proposed modified electrode will be a suitable platform for futuristic clinical biosensing applications.
