Abstract: The current research focuses on nano-material suspensions and flow characteristics in the context of their applications. The use of such materials in biomedical rheological models has garnered considerable attention. Having such practical and potential applications of nanofluids our goal is to analyse the radiative flow of Maxwell nanoliquid on a stretching cylinder by considering magnetic effect, Stefan blowing and bioconvection. By selecting appropriate similarity variables, the equations that reflect the stated flow are transformed to ordinary differential equations. A Runge-Kutta-Fehlberg fourth-fifth order method (RKF-45) along with shooting scheme is used to solve the reduced equations. Graphical representations are used to give a clear knowledge of the behavior of dimensionless parameters on dimensionless velocity, concentration, and thermal profiles, which are strategized and debated by using physical descriptions. The significant results claimed via reported model convinced a declining velocity change due to curvature constant. The upshot change in thermal and mass relaxation times parameters declines the thermal and concentration pattern, respectively. The peak fluctuation in Brownian factor advances the thermal profile but declines the concentration profile. The rise in values of microorganism difference parameter and Peclet number declines the concentration of microorganisms.
