This paper provides a synopsis of the advancements made in advancing a dendrimer-based nanomedicine towards human clinical trials by the Michigan Nanotechnology Institute for Medicine and Biological Sciences. A brief description of the synthesis and characterization of a targeted multifunctional therapeutic will demonstrate the simple yet delicate task of producing novel chemotherapeutic agents. The results obtained from in vitro and in vivo studies not only authenticate the potential of using nanoparticles to target therapeutics but also provide valuable insight towards the future directions of this technology. A fundamental, cross-disciplinary collaboration was necessary to achieve the synthesis and testing of this technology, and was the keystone to establishing this innovative invention. Throughout this paper, we will stress that the unique collaboration that facilitated the evolution of this technology is vital to the success of future developments in nanomedicine.

This study aims to synthesize a new localized drug delivery system of bioglass, polyvinyl alcohol (PVA), cellulose (CNC), and sodium alginate (SA) beads as a carrier for methotrexate (MTX) drugs for the treatment of osteosarcoma. Methotrexate /Bioglass-loaded Polyvinyl/Cellulose/Sodium alginate biocomposite beads were prepared via the dropwise method with different concentrations of (65%SiO-30%CaO- 5%PO) bioglass. Samples were named B0, S0, S1, S2, and S3, respectively.

This investigation aimed to enhance transdermal methotrexate delivery through human skin by employing Dr. Pen microneedles and poly(d,l-lactide--glycolide) acid microparticles formulated from eight polymer grades (Expansorb DLG 95-4A, DLG 75-5A, DLG 50-2A, DLG 50-5A, DLG 50-8A, DLG 50-6P, DLG 50-7P, and DLL 10-15A). A comprehensive characterization of the microparticles was performed, encompassing various parameters such as size, charge, morphology, microencapsulation efficiency, yield, release kinetics, and chemical composition.

Background: This study aimed to investigate the risk factors related to the failure of initial combined local methotrexate (MTX) treatment and minimally invasive surgery for late cesarean scar pregnancy (CSP).
Methods: This retrospective case-control study was conducted between January 2016 and December 2023, involving patients with late CSP (≥ 8 weeks) who received local MTX injection combined with either hysteroscopic or laparoscopic surgery. Cesarean scar pregnancy was classified as type I, II, or III based on the direction of growth of the gestational sac and the residual myometrial thickness as assessed by ultrasound.

The simultaneous administration of multiple drugs within identical nanocarriers to cancer cells or tissues can result in the effective action of drugs at reduced concentrations. In this investigation, PAMAM dendrimers (G4-PAMAM) were employed to link with methotrexate (MTX) using DCC/NHS chemistry and followed by the entrapment of curcumin (Cur) within it. The establishment of covalent bonds between MTX and the PAMAM dendrimer led to PAMAM-MTX interaction, verified and described through FT-IR.
