To address the issue of nonspecific biodistribution a chemotherapeutic drug, stable [2]pseudorotaxane complexes (PK@CAOPP and PR@CAOPP) are used to demonstrate proof concept. Cationic -PPh3 + moiety in CAOPP allows specific localization PK@CAOPP/ PR@CAOPP mitochondrial membrane (MM). Electrostatic interaction between cationic LysinePK or ArgininePR negatively charged phosphoesterCAOPP functionality favours strong adduct formation. The ALP-induced hydrolytic cleavage phosphoester cancer cells triggers dephosphorylation releases PK/ PR from PK@CAOPP/PR@CAOPP. PK PR, derived Phe-Phe dipeptide, formed fibril-like molecular aggregates MM induce dysfunction, depolarization, ROS generation apoptotic MCF7 cell death. Such phenomena were not observed ALP-negative HEK293 normal cells. These propositions confirmed through control studies using NBDK PE, other guest molecules. Smaller size inclusion short peptides (PK PR) within hydrophobic interior CAOPP, attributed their stability blood serum. Thus, we have demonstrated use supramolecular adducts as potential therapeutic option for treating without affecting healthy efficacy was also established with an in-vivo tumour xenograft model Balb/c nude mice.

Fabrication of stimuli-responsive superstructure capable delivering chemotherapeutics directly to the cancer cell by sparing healthy cells is crucial. Herein, we developed redox-responsive hollow spherical assemblies through self-assembly disulfide-linked cysteine-diphenylalanine (SN). These fluorescent spheres display intrinsic green fluorescence, are proteolytically stable and biocompatible, allow for real-time monitoring their intracellular entry. The disulfide bond facilitates selective degradation in presence high glutathione (GSH) concentrations, prevalent cells. We achieved efficient encapsulation (68.72%) anticancer drug doxorubicin (Dox) demonstrated GSH-dependent, release within cancerous SN-Dox exhibited a 20-fold lower effective concentration (2.5 μM) compromising breast viability compared non-malignant (50 μM). ability initiate DNA damage signaling trigger apoptosis was comparable that unencapsulated drug. Our findings highlight potential SN creating site-specific delivery vehicles sustained therapeutic release.

Soft robotics has been rapidly advancing, offering significant improvements over traditional rigid robotic systems through the use of compliant materials that enhance adaptability and interaction with environment. However, current approaches face critical challenges, including reliance on complex "top-down" fabrication techniques difficulty wireless powering control at microscale. Swarm introduces a paradigm shift, leveraging collective dynamics to achieve cooperative adaptable behaviors among multiple units. Inspired by nature, this "bottom-up" approach enables swarm robots execute task-specific reconfigurations, enhancing flexibility robustness. Field-driven active colloids emerge as promising platform for microrobotics, capable self-propulsion self-organization into dynamic patterns under external field excitation manipulation. These mimic biologically inspired behaviors, such flocking vortex formation, providing versatile foundation designing innovative microrobots. This review discusses principles electric magnetic field-driven self-organization, focusing particle dynamics, emergence patterns, illustrative examples functional It concludes future perspectives harnessing these adaptive, scalable, multifunctional microrobotic applications.
