Cancer treatment has historically depended on conventional methods like chemotherapy, radiation, and surgery; however, these strategies frequently present considerable limitations, including toxicity, resistance, negative impacts healthy tissues. In addressing challenges, drug-free cancer therapies have developed as viable alternatives, utilizing advanced physical biological to specifically target tumor cells while reducing damage normal This review examines several strategies, such high-intensity focused energy beams, nanosecond pulsed electric fields, photothermal therapy well the use of inorganic nanoparticles promote selective apoptosis. We also investigate significance targeting microenvironment, precision medicine, immunotherapy in progression personalized therapies. Although approaches demonstrate significant promise, challenges scalability, safety, regulatory obstacles must be resolved for clinical application. paper presents an overview current research therapies, emphasizing recent advancements, underlying scientific principles, steps required implementation.

This study presents a targeted impedimetric immunosensor for the detection of procalcitonin (PCT), biomarker associated with SEPSIS. The was operated based on interaction between PCT antibody (anti‐PCT) and antigen, utilizing graphene quantum dot (GQD)‐modified carbon screen‐printed electrode (SPCE). Herein, GQDs, known their large surface area excellent electrical conductivity, served as matrix immobilizing anti‐PCT, thereby enhancing electrochemical signal. Following immobilization anti‐PCT onto GQD@SPCE, antigen monitored by using impedance spectroscopy. Experimental parameters were optimized, analytical characteristics extensively evaluated. developed demonstrated linear range 0.1–10 ng/mL PCT, limit 0.01 quantification 0.03 ng/mL. Finally, GQD‐based applied to low‐ high‐level original control serum samples selected kit very promising recovery values obtained.

Introduction Ginger, as a traditional Chinese medicine (TCM), can be used in clinical practice to treat various diseases. The product of ginger processed at high temperatures is called carbonized (CG), which has hemostatic effect that originally did not have. purpose this study investigate the CG and substances exert effects. Methods was prepared successfully obtained carbon dots (CG-CDs) from its aqueous solution. After fully characterizing structural information, evaluated using mouse tail bleeding liver injury models, clotting time capillary coagulation experiments. In addition, mechanism CG-CDs explored. Results average particle size observed 4.07 nm lattice spacing 0.216 nm. It mainly composed graphite structured carbon, with main constituent elements being C, N, O, containing functional groups such C=N, C=O, C-OH. FL spectrum showed maximum excitation wavelength 360 nm, emission 470 QY calculated 0.45%. shortened time, reduced volume, also for blood clotting. With increase CG-CDs, values FIB gradually increased, PT decreased. increased PLT count, activating factor TXB2, decreased 6-keto-PGF 1 α , PAI-1, t-PA. Conclusion activity, by exogenous co-coagulation pathways, increasing reducing t-PA, thereby affecting fibrinolytic system other pathways
