Eco-friendly synthesis of carbon nanotubes and their cancer theranostic applications

Abstract

Carbon nanotubes (CNTs) with attractive physicochemical characteristics such as high surface area, mechanical strength, functionality, and electrical/thermal conductivity have been widely studied in different fields of science. However, the preparation...

Aggregation-Induced Emission (AIE), Life and Health

“…Despite significant breakthroughs in cancer therapy over the past few decades, effective diagnosis and subsequent therapeutic interventions remain challenging. − Compared with traditional treatment methods, phototheranostics, emerging as a promising pattern of cancer therapy, integrates photoinduced diagnostic imaging and concurrent in situ therapy into a single formulation with the merits of high spatiotemporal precision and noninvasiveness. − The working mechanism behind phototheranostics is that a fluorophore transfers the absorbed photon energy into different forms of energy for disease diagnosis and therapy . On the one hand, when the absorbed photon energy of molecules relaxes through a radiative pathway, the generated fluorescence signal could be used for diagnostic fluorescence imaging with the merits of high sensitivity, real-time tracking ability, high spatiotemporal resolution, and noninvasiveness .…”

MXene-Carbon Nanotube Composites: Properties and Applications

“…On the other hand, CNTs with suitable interfacial area, multifunctionality, and needle-like shapes have been fabricated using carbon arc discharge, spray pyrolysis, chemical vapor deposition, flame synthesis, laser-ablation, etc. [ 19 , 20 ]. The unique properties of CNTs such as good heat conduction, tensile strength, flexibility, hollow monolithic structures, suitable penetrability, and optico-electrical features make them promising candidates in environmental sciences and bio- and nanomedicine domains [ 21 , 22 ].…”

Self-assembled aggregates based on cationic amphiphilic peptides: structural insight

“…An example is the integrin peptide, RGD, which has been derivatized at the N-terminus with a fluorenyl (Fmoc-) group 29,30 or with alkyl chains (C14, C16, C18) [31][32][33] to promote its aggregation into selfsupporting hydrogels. Analogously, some targeting peptides like CCK8, 34 [7][8][9][10][11][12][13][14] bombesin 35 and octreotide 36 have been decorated with two alkyl chains with eighteen carbon atoms to generate micelles. In this context, some of us recently reported the synthesis of a small library of cationic peptides, 37 which selfassemble into promising hydrogels for tissue engineering applications.…”

“…Supramolecular architectures like micelles, 1–3 liposomes, 4–7 nanotubes, 8,9 fibers 10,11 and hydrogels 12–16 have been proposed for many biomedical applications including delivery of genetic materials, therapeutic and/or diagnostic agents, and as platforms for tissue engineering and regeneration. These structures are generally based on noncovalent bonds (including hydrogen bonding, metal coordination, hydrophobic, van der Waals, and electrostatic and π–π interactions) within and between molecules.…”
