1. Introduction
The incidence of malignant cancers continues to rise each year and thus, the development of new treatment methods is still much needed to combat this disease. Besides the
application of surgery, chemotherapy, and radiation, cancer cell death can also be induced
by immunotherapy, which is a relatively newer and promising concept to combat cancer.
The body’s natural immune responses are often suppressed in the tumor microenvironment. Immunotherapy can be applied to activate or enhance the host immune system
response to attack and destroy tumor cells [1]. Although it offers an emerging and novel
way to treat cancer, the efficiency of immunotherapy alone is underwhelming with little
to no response rates in many cases [2,3]. As such, strategies to enhance or supplement
immunotherapy are much needed. Chemotherapy, which is often the frontline treatment
method for different cancers, is usually associated with having immunosuppressive
effects, therefore, it was originally not considered as a combination therapy with cancer
immunotherapy [4]. However, in recent years, chemotherapy and immunotherapy combinations have shown promising results and offer a promising avenue to increase response
rates and possible outcomes in synergized anticancer effect [1]. The synergistic or combined effects of these agents may allow for the decreased dosage of each agent and thus,
minimizing their unwanted side effects.
Biotechnology approaches, including nanoscale biomaterials and microrobots/
nanorobots (MNRs), have special characteristics that are useful to increase the efficacy
and reduce the nontarget side effects of traditional treatment methods. In this chapter,
nanoscale biomaterial-based strategies that have been utilized to deliver both an immunotherapy and a chemotherapy agent via biomaterials (i.e., dual delivery of both agents with
the same biomaterial or separate biomaterials, for example, using two different liposomes)
or only the immunotherapy agent with biomaterials (i.e., the chemotherapy agent is delivered systemically or locally, without a biomaterial) are discussed, as summarized in Fig. 1.
Fig. 1 Summary of the immunotherapy and chemotherapy combination that have been investigated
using different nanoscale biomaterial-based strategies.

Nanosized biomaterials have turned out to be very effective as drug carriers since they can
provide a better-controlled delivery, thus reduce toxicity, and improve efficacy by several
ways, such as by increasing drug uptake. Due to their ultrasmall size, NPs can pass across
tissue barriers and reach tumor cells, being up-taken by tumor cell through the enhanced
permeability and retention (EPR) effect. In contrast to macro-scaled biomaterials [5],
which can result in local delivery at the implanted site, nanosized objects even if delivered
locally, can easily escape to other tissues, posing the need for a targeted delivery using different strategies, usually based on chemical recognition, such as cell type affinity via specific
ligand overexpression.
Table 1 shows the specific chemotherapy and immunotherapy agents that have been
investigated and delivered using nanoscale biomaterial-based strategies to increase their
efficacy and the major outcomes from the combination therapies. Moreover, by using
chemically or physically active biomaterials, for example, biomaterial-based microobjects/nanoobjects, provided with actuation systems, which can be driven from the
outside, even more targeted delivery can be obtained. MNRs usually need multibiomaterials and a more complex architecture than NPs, thus are considered as small
devices, and are becoming very attractive in cancerous pathology and other diseases.
To this purpose, we bring attention to the MNRs as the next step of biomaterial-based
devices that have the potential of delivering combined immune-chemo therapy.

2. Immunotherapy and chemotherapy combinations
In the following sections, the mechanisms of action of the immunotherapy and
chemotherapy agents that have been used as a combination, availing themselves of nanoscale biomaterial-based strategies to increase their efficacy are discussed.
2.1 PD-1 and PD-L1 inhibition
Programmed cell death protein 1 (PD-1) plays a vital role in the inhibition of both the
adaptive and innate immune responses by modulating the activity of T-cells, activating
apoptosis of antigen-specific T cells, and inhibiting apoptosis of regulatory T cells [16].
PD-1 is expressed on activated T, natural killer (NK) and B lymphocytes, macrophages,
dendritic cells (DCs), and monocytes and is highly expressed on tumor-specific T cells
[17]. The two known ligands of the PD-1 receptor are PD-L1 and PD-L2, which are
regulated by cytokines such as interferon (IFN) and tumor necrosis factor alpha
(TNF-α) expressed in T, B, endothelial, and epithelial cells [18]. The PD-1/PD-L1 pathway plays particular important roles in suppressing antitumor immunity by inhibiting the
activation of T-cell, lysing of tumor cell or the induction of tumor-specific T cell apoptosis [18]. The tumor microenvironment has been found to upregulate levels of PD-L1
and studies have shown that anti-PD-1 or anti-PD-L1 can restore T-cell activity and
improve immune response and thus, are great target for cancer immunotherapy [19].

PD-1and PD-L1inhibitionworks by blockingthe bindingof PD-1 to PD-L1, whichresults
in “unmaskingtumor cells,” thus allowing the activation of T cells that are able to ultimately
get rid of the tumor cells [4,6].
2.1.1 PD-L1 inhibitor and doxorubicin
Liu et al. investigated the combined delivery of the immunotherapy agent, PD-L1 inhibitor, and the chemotherapy drug, doxorubicin (Dox) with liposomes [4]. The PD-L1
inhibitor can disrupt the interaction of PD-1 and PD-L1, and thus, resulting in T-cell
activation. As a chemotherapy drug, Dox functions by intercalating within DNA,
resulting in the prevention of topoisomerases II ability of DNA repair [20]. A low dose
of Dox can also help to enhance immunotherapy. It sensitizes tumor cells to cytotoxic
T lymphocytes (CTLs) through the process of upregulation and presentation of
mannose-6-phosphate (M6P) receptors on the tumor cells. This results in increased
tumor cell apoptosis since the permeability of granzyme B (GranB or Grzb2), a critical
mediator of apoptosis, is increased as depicted in Fig. 2.

2.1.2 Anti-PD-1 and cisplatin
Anti-PD-1 is known as an immune checkpoint inhibitor and is a type of immunotherapy that
is widely investigated as it has been revealed to be effective in a range of cancers. However, it is
associated with low response rates and the development of resistance to this inhibitor [6].To
overcome this, Lan et al. studied the combination of the immunotherapy agent, anti-PD-1,
and another chemotherapy agent, cisplatin (CDDP) using lipid NPs [6].Platinum-based
drugs such as CDDP can result in resistance due to diminish nuclear accumulation of the drug
in cancer cells by fibroblasts [21]. CDDP chemoresistance can be abolished with CD8 +
Tcells[21]; moreover, it has been shown that clonal expansion of T-cells can result in
enhanced responsiveness to chemotherapy [22]. Thus, combining CDDP with immunotherapy can make it more effective. Lan et al. demonstrated that the anti-PD-1 + CDDP group
exhibited a greater effect in an in vivo tumor model than the anti-PD-1 or CDDP groups
alone. They concluded that CDDP could inhibit cell proliferation, and anti-PD-1 could
enhance T-cell infiltration. The enhanced T-cell activity exerted by anti-PD-1 resulted in
tumor cell apoptosis, leading to synergistic anticancer effects with CDDP.
2.2 Selenium
Selenium has been shown to sensitize cancer cells to NK cells due to oxidative stress [7].
The natural killer group 2A (NKG2A) is an inhibitory checkpoint receptor present on
cancer cells that protects them from being targeted by NK cells. NKG2A binds to human
leukocyte antigen-E (HLA-E), thus it decreases the expression of HLA-E, rendering cancer cells susceptible to NK cells. Selenium blocks HLA-E expression in cancer cells at the
posttranscriptional level through increased intracellular oxidative stress [23].
103Biomaterials and devices for immunotherapy
2.2.1 Selenium and doxorubicin
Gao et al. tested the possible synergistic effects of the immunotherapy agent, selenium,
and the chemotherapy drug, Dox [7]. The selenium (Se)- containing NPs was the delivery vehicle for Dox and also served as the immunotherapy. Gamma-radiation can cleave
the diselenide bonds in the NPs, leading to seleninic acid which has the same anticancer
effect as selenide, therefore, can also induce a decrease in HLA-E expression and an
increase in NK cell-related tumor death. In addition to its chemotherapeutic and immunologic effects detailed in previous combination therapies, Dox has also been shown to be
able to enhance NK cell-mediated antitumor effects (i.e., NK mediated killing) through
the TRAIL pathway [24]. This is done through the activation of caspase 8 by its cleavage
which signals the apoptotic pathway of TRAIL.
2.3 Heme oxygenase 1 (HO-1) inhibitors
Heme oxygenase 1 (HO-1) is an antioxidative and cytoprotective enzyme, which protects against inflammatory processes found in certain chemoresistant cancers and is also

known as an immune checkpoint molecule [8]. Thus, HO-1 inhibitors can induce an
antitumor immune response.
2.3.1 Tin mesoporphyrin (a HO-1 inhibitor) and daunorubicin
Yong et al. investigated the delivery of an HO-1 inhibitor, tin mesoporphyrin (SnMP)
with lipid polymer nanoparticles and in combination with systemic daunorubicin
(DNR), a chemotherapy drug. They found that HO-1 inhibition was able to promote
the immune response by reprogramming bone marrow myeloid cells. Furthermore,
HO-1 inhibition was able to enhance the chemotherapeutic effect of DNR, which confirms the synergistic effect of using a chemotherapy and immunotherapy agent in combating cancer (Fig. 3).
2.4 Interleukin-2
Interleukin-2 (IL-2) mediates its antitumor effect through the generation of lymphokineactivated killer (LAK) cells [25]. LAK cells are capable of lysing NK cell-resistant tumor
cell targets. Studies to define the in vivo role of IL-2 have documented that the lymphokine can promote the expansion of transferred LAK cells [26], as well as immune T-cells
[27,28]. The administration of IL-2 alone also stimulates the proliferation of endogenous
lymphoid cells, which, when recovered from tissues, have lytic activity for fresh tumors
in in vitro assays [29].
2.4.1 Interleukin-2 and doxorubicin
High and frequent doses of IL-2 are needed to achieve a significant response due to the
rapid clearance of this cytokine which can lead to serious side effects due to its association
with vascular leakage syndrome [29–32]. This can result in capillary leakage, cardiac
