“…However, substantial efforts are still necessary to provide touch sensations closer to the natural ones 13 . In particular, both the physical characteristics of the physiological tactile sensors and their firing properties have to be replicated 14,15 to create a more effective and natural connection with the peripheral nerves and therefore a more effective sensory restoration. This goal can be reached by exploiting the principle of "morphological computation" 16 for neuroprosthetic applications, i.e., the embodiment of aspects of neuronal information processing into the physical structure of the system.…”

Humans rely on their sense of touch to interact with the environment. Thus, restoring lost tactile sensory capabilities in amputees would advance their quality of life. In particular, texture discrimination is an important component for the interaction with the environment, but its restoration in amputees has been so far limited to simplified gratings. Here we show that naturalistic textures can be discriminated by trans-radial amputees using intraneural peripheral stimulation and tactile sensors located close to the outer layer of the artificial skin. These sensors exploit the morphological neural computation (MNC) approach, i.e., the embodiment of neural computational functions into the physical structure of the device, encoding normal and shear stress to guarantee a faithful neural temporal representation of stimulus spatial structure. Two trans-radial amputees successfully discriminated naturalistic textures via the MNC-based tactile feedback. The results also allowed to shed light on the relevance of spike temporal encoding in the mechanisms used to discriminate naturalistic textures. Our findings pave the way to the development of more natural bionic limbs.

“…Due to the high absorption coefficient and superior capabilities of energy-, hydrogen-and electron-transfer, porphyrins present diverse outstanding photophysical and photochemical properties. These intrinsic superior properties of porphyrin render their extravagant studies in solar cells, [10][11][12] catalysis, [13] imaging, [14] molecular electronics [15] and biomedicines [16]. Considering the several reviews, summarizing the synthesis, self-assembly, and applications of porphyrins in solar cells, catalysis, imaging and drug delivery, the aim of this review is to specifically focus the porphyrin-based materials for photodynamic therapy in the last five years.…”

“…Because of the amphiphilicity of porphyrin lipids, they could directly self-assemble into porphyrin liposomes in physiological condition with the porphyrin motifs at the walls. Such smart self-arrangement induced the fascinating merits of porphyrin-liposomes adducts including the remarkable bioimaging, [14] photodynamic [62] and photothermal effects [58]. To support this hypothesis, TPP was grafted onto the lipid at the junction point to obtain lipid-porphyrin conjugates which further encapsulated the DOX and cholesterol.…”

Porphyrin macromolecules play critical roles in many natural processes. Studies are going on to mimic their role in natural systems and use them in various applications in artificial systems. When a porphyrin moiety is conjugated with carbon nanoallotropes, viz., carbon nanomaterials, carbon nanotubes, carbon nanospheres, etc., the hybrid molecules show optimized properties compared to the pristine molecules. In this review, various mechanisms of conjugating carbon nanoallotropes/carbon nanomaterials and porphyrins through stable chemical bond formation are discussed. The non-covalent interactions which cause their aggregation without disrupting their electronic structures are also discussed. This review also gives vital information on the utilization of conjugated systems effectively for society oriented applications.________________________________________
