Different nanocarriers being utilized for targeting TME to overcome multi-drug resistance: (a) Nanoparticles loaded with two different drugs for co-delivery at target site for synergistic therapeutic action. (b) Theranostic nanoparticles co-loaded with both therapeutic and diagnostic agents. (c) Stimuli responsive nanoparticles respond against different components of TME such as pH change, ions change, different oxygenation. (d) Multifunctional branched polymeric dendrimer-based nanocarrier loaded with drugs. (e) Nanoparticles loaded with both drugs and nucleic acids (siRNA, miRNA) for synergistic therapeutic action (f) Liposomes loaded drugs for targeted delivery. Reproduced from Ref.
