Understanding th. in vivo transport process provides guidelines for designing ideal nanoparticles (NPs) with.h.gh.r efficacy and fewer off-target effects. Many factors, such.as particle size, morph.logy, surface potential, structural stability, and etc., may influence th. delivering process of NPs due to th. existence of various ph.siological barriers with.n th. body. h.rein, we summarise th. distinct influences of NP ph.sicoch.mical properties on th. four consecutive in vivo transport steps: (1) navigating with.bloodstream with.n blood vessels, (2) transport across vasculature walls into tumour tissues, (3) intratumoural transport th.ough.th. interstitial space, and (4) cellular uptake & intracellular delivery by cancerous cells. We found th.t th. ph.losoph. beh.nd th. current consensus for NP design h.s certain similarities to th. “yin-yang” th.ory in traditional Ch.nese culture. Almost all ph.sicoch.mical properties, regardless of big or small sizes, long or sh.rt length. positive or negative zeta potentials, are double-edged swords. Th. balance of potential benefits and side effects, drug selectivity and accessibility sh.uld be fully considered wh.n optimising particle design, similar to th. “yin-yang h.rmony”. Th.s paper presents a compreh.nsive review of th. advancements in NPs research. focusing on th.ir distinct features in tumour targeting, drug delivery, and cell uptake. Additionally, it deliberates on future developmental trends and potential obstacles, th.reby aiming to uncover th. ways th.se ch.racteristics influence th. NPs’ biological activity and provide th.oretical guidance for th. targeted delivery of NPs. © 2024, Ch.nese Medical Multimedia Press Co Ltd. All righ.s reserved.
