Different nanomaterials have been combined with imaging and sensing techniques and amplification methods to facilitate the less time-consuming and easy detection of SNPs in different diseases. This review aims to highlight some of the most recent findings on the aspects of nanotechnology-based SNP sensing methods used for the specific and ultrasensitive detection of low-concentration SNPs and rare mutations.In this study, we explore the role that isolation and loneliness play in the narratives of women diagnosed with perinatal depression. Isolation and loneliness are increasingly seen as risk factors for depression, including in the perinatal period, but little is known about whether, and in what ways, women themselves associate isolation or loneliness with perinatal distress. Based on the thematic analysis of semi-structured interviews with fourteen mothers in England, we found that women often connected feelings of depression during and after pregnancy to feeling dislocated from their previous identities and relationships. Women felt lost, confined to their homes, and often unsupported by their partners and families. However, fears of being judged to be inadequate mothers made it difficult for women to make authentic connections with others or to express negative feelings, increasing isolation and depression. We drew on the intersectionality theory to illustrate how the intersect between motherhood and other aspects of women's identities (being young, single, deprived and/or from an ethnic minority) could leave some women particularly isolated and marginalised. Our conclusions emphasise the need to challenge social constructions of the good/bad mother, ad
