Special Issue in Micromachines: Nanomechanical Biosensors
Cancer is a leading cause of death globally. The World Health Organization (WHO) estimates that approximately nine million people die of cancer every year. The battle against cancer gathers today researchers across diverse fields in science. Nanoscience and nanotechnology advancements can offer innovative research avenues and new tools to deepen our understanding about cancer initiation and evolution of the disease. Additionally, nanomaterials have shown great promise for the development of better cancer treatment strategies and nanosensors have the potential to provide early detection of the disease.
In this Special Issue, research in nanoscience and nanotechnology focused to answer the challenges in cancer diagnosis and treatment will be gathered to provide a wide and deep understanding of the field today.
It is our pleasure to invite you to submit a manuscript for this Special Issue. Full papers, communications, and reviews are all welcome.

1. Title: Nanocomplexes of graphene oxide and platinum nanoparticles against colorectal cancer Colo205, HT-29, HTC-116, SW480, liver cancer HepG2, human breast cancer MCF-7 and adenocarcinoma LNCaP and human cervical Hela B cells line

Abstract: The formation of cancer cells is related to the genetic mutation, abnormalities at hormone and immune conditions, which have also an impact on the chemoresistance of cancer cells. The insufficient drug administration into cancer cells is related to cancer resistance caused by the genetic mutations including genes involved in the drug transport, metabolizing enzymes and/or DNA damage repairs.
The objective of the present study has been to evaluate properties of platinum (NP-Pt), graphene oxide (GO) and the nanocomplex of GO functionalized with platinum nanoparticles (GO-Pt) against several genetically, phenotypically and metabolically different cancer cells line: Colo205, HT-29, HTC-116, SW480, HepG2, MCF-7, LNCaP and Hela B. The anticancer effects toward cancer cell lines were evaluated by XTT and BrdU assays and measurements of cell apoptosis and morphology deformations. GO was effectively combined with NP-Pt by in situ ultrasonication, forming a nanocomplex of GO-Pt. NP-Pt and GO could be efficiently introduced to cancer cells, but more effective delivery was observed after GO-Pt treatment. The delivery of GO-Pt nanocomplex significantly decreased the viability of HepG2 and Colo 205 cells but did not increase the cytotoxicity of other investigated cancer cells. Nanocomplexes of GO-Pt increased the apoptosis of MCF-7 and HepG2 cancer cells, while the GO treatment did not affect the apoptosis.
The obtained results suggest that the nanocomplex of GO-Pt is a noteworthy nanostructure that can improve the delivery of Pt nanoparticles into cancer cells and has potential anticancer applications.
2. Title: The application to cancer immunotherapy with the recombinant bifidobacteria secreting TNF-α in mouse melanoma model

Abstract: Tumor necrosis factor alpha (TNF-α) is known to induce the apoptosis on various tumor cells. But cancer treatments by the systemic administration of TNF-α has been unsuccessful because of severe harmful side effects, such as hepatic dysfunction, and thus the application of TNF-α protein preparation to cancer therapy should be delivered exclusively to the tumor tissue. In this report, we will describe about recombinant Bifidobacteria as the drug delivery carrier for the tumor tissues. Bifidobacteria, widely known as one of “good bacteria”, are anaerobic gram-positive bacteria found in the normal bacterial flora. When they are administered directly into the blood stream, they can strictly enter into the hypoxygenic tumor tissues by their anaerobicity and enhanced permeability and retention (EPR) effect. According to these properties of Bifidobacteria, we have invented the clone of TNF-α-expressing recombinant Bifidobacteria, named M4, as the vehicle for TNF-α protein. M4 could secrete TNF-α protein which has an almost equal physiological activity to that of commercially available purified specimen. Intravenously administered M4 exhibited an anti-tumor activity against several mice or human tumor cell lines in vivo. In the M4 bacteria-administered syngenic tumor bearing mice models, the number of CD8-positive cells in their tumor tissues was significantly increased. This indicates that immune cells were gathered by TNF-α protein secreted by recombinant M4 bacteria in the tumor tissue. These results suggest that the Bifidobacterial clone M4 could exhibit anti-tumor activity by the chemoattraction of immune cells into the tumor cells as well as the apoptosis-inducing activity. Since no significant harmful effect was observed in M4 bacteria-administered mice, the recombinant Bifodobacteria will be a possible therapeutic option for delivering TNF-α protein to treat cancer.
3. Title: Silver, gold, and iron oxide nanoparticles alter miRNA expression but do not affect DNA methylation in HepG2 cells.

Abstract: The increasing use of nanoparticles (NPs) in various applications entails the need for reliable assessment of their potential toxicity for humans. Originally, studies concerning NPs toxicity focused on cytotoxic and genotoxic effects but more recently, attention has been paid on epigenetic changes induced by nanoparticles. In the present research, we analyse the DNA methylation status of genes related to inflammation and apoptosis as well as expression of miRNAs related to these processes in response to silver (AgNPs), gold (AuNPs), and superparamagnetic iron oxide nanoparticles (SPIONs) at low cytotoxic doses in HepG2 cells. There were no significant differences between treated and control cells in the DNA methylation status. We have identified nine miRNAs which expression was significantly altered by treatment with nanoparticles. The highest number of changes has been induced by AgNPs (6 miRNAs), followed by AuNPs (4 miRNAs) and SPIONs (2 miRNAs). Among others, AgNPs suppressed miR-34a expression that is of particular interest, since it may be responsible for the previously observed AgNPs-mediated HepG2 cells sensitisation to TNF. Most of the miRNAs affected by NPs treatment in the present study have been previously shown to inhibit cell proliferation and tumorigenesis. However, based on the observed changes in miRNA expression we cannot draw definite conclusions regarding pro- or antitumoral nature of NPs under study. Further research is needed to fully elucidate the relation between observed changes in miRNA expression and NPs effects observed on the cellular level. The results of the present study support the idea of including epigenetic testing during the toxicological assessment of the biological interaction of nanomaterials.
