Figure 3

(a) Mini-microscope fabricated by reversing the lens of a webcam and its use to observe hepatic cancer spheroids. Adapted with permission from Ref. [30] and Ref. [31]. (b) Portable microscope using flipped cellphone lenses and a Fourier ptychographic algorithm to stitch images captured from a sample illuminated by different angles with an LED array and its use in observation of histopathological samples. Reproduced with permission from Ref. [32]. (c) Lens-free portable microscope to obtain holographic images and its use to image cells infected with malaria parasites Reproduced with permission from Ref. [39]. (d) Lens-free portable tomographic microscope and its use to observe an egg of parasitic worm. Reproduced with permission from Ref. [40]. (e) Portable microscope adapted to a smart phone, based on the reconstruction of diffraction patterns and its use to analyze cervical cancer. Reproduced with permission from Ref. [41].
