Abstract It observers that an object is submerged in a liquid, more pressure applied to its bottom surface than top surface, as result rises within depth of fluids. A buoyancy force generated due the difference. In current investigation, mathematical formulation bio-convective stagnation point flow radiative Maxwell fluid with multiple slip effect on exponentially porous stretching analyzed thoroughly. The assisting and opposing conditions magnetic field are discussed investigation. Moreover, energy concertation equations formulated by utilization Cattaneo–Christov theory non-uniform heat source/sink. model developed form partial derivatives, then use similarity variables convert physical system into nonlinear ordinary derivative. tackled numerically help Bvp4c approach MATLAB. graphical upshots for various emerging parameter observed two aspects: $$\left( {\lambda &gt; 0} \right)$$ <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:mfenced> <mml:mrow> <mml:mi>λ</mml:mi> <mml:mo>&gt;</mml:mo> <mml:mn>0</mml:mn> </mml:mrow> </mml:mfenced> </mml:math> &lt; <mml:mo>&lt;</mml:mo> . observation shows greater values mixed convection improves velocity , while declining trend noticing situation Further, it worth stronger inputs thermal concentration relaxation yield lesser diffusivity, which reduces temperature nanoparticles concentration.
