Nanoteknologi telah merevolusi berbagai bidang, termasuk kedokteran, dengan memberikan peluang baru untuk penelitian dan aplikasi. Penelitian ini berfokus pada karakterisasi nanopartikel yang berasal dari ekstrak daun sirsak. Nanopartikel disintesis menggunakan polimer kitosan dan ekstrak daun sirsak, dan sifat-sifatnya dianalisis. Hasil penelitian menunjukkan rentang ukuran partikel yang luas, dengan ukuran rata-rata 210,9 nm dan modus 161,4 nm. Nanopartikel menunjukkan potensial zeta negatif sebesar -31,5 mV, yang menunjukkan stabilitasnya dalam larutan. Efisiensi penyerapan ditemukan sebesar 87,90%, dan kapasitas muatan obat mencapai 37,92%. Mikroskop elektron pemindaian mengonfirmasi morfologi nanopartikel yang berbentuk bulat. Temuan ini menyoroti potensi nanopartikel dari ekstrak daun sirsak untuk pengiriman obat dan menekankan pentingnya karakterisasi komprehensif untuk aplikasi di masa depan.

Carbon-based nanomaterials, such as carbon quantum dots (CQDs) and carbon 2D nanosheets (graphene, graphene oxide, and graphdiyne), have shown remarkable potential in various biological applications. CQDs offer tunable photoluminescence and excellent biocompatibility, making them suitable for bioimaging, drug delivery, biosensing, and photodynamic therapy. Additionally, CQDs’ unique properties enable bioimaging-guided therapy and targeted imaging of biomolecules. On the other hand, carbon 2D nanosheets exhibit exceptional physicochemical attributes, with graphene excelling in biosensing and bioimaging, also in drug delivery and antimicrobial applications, and graphdiyne in tissue engineering. Their properties, such as tunable porosity and high surface area, contribute to controlled drug release and enhanced tissue regeneration. However, challenges, including long-term biocompatibility and large-scale synthesis, necessitate further research. Potential future directions encompass theranostics, immunomodulation, neural interfaces, bioelectronic medicine, and expanding bioimaging capabilities. In summary, both CQDs and carbon 2D nanosheets hold promise to revolutionize biomedical sciences, offering innovative solutions and improved therapies in diverse biological contexts. Addressing current challenges will unlock their full potential and can shape the future of medicine and biotechnology.

“…It is revealed that the complex tumor biological environment, for example, abnormal vasculature and tumor heterogeneity, compromises PDT efficiency. 7,8 These unfavorable factors in tumors not only create barriers to the effective delivery of photosensitizer (PS) reagents but also cause the hypoxic environment in tumors. [9][10][11][12][13] In terms of tumor PDT, the effective tumor enrichment of PSs is the rst prerequisite, 14 because increasing tumor PS enrichment can reduce the toxic side effects on normal tissues by cutting down the amounts of PSs injected or the intake of normal tissues.…”
